Chapters

00:00 - 01:30: Introduction and Housekeeping The chapter 'Introduction and Housekeeping' introduces the session by welcoming the participants to the third meeting. It aims to make the participants aware of historical and contemporary issues related to the topic of discussion.
01:30 - 03:30: Group Dynamics and Course Expectations This chapter covers housekeeping details regarding course participation and group dynamics. It emphasizes the importance of communication if joining the course late, to avoid issues like being left out of group activities. The instructor highlights the need to inform them to prevent any misunderstandings and unnecessary drama related to group formations and participation.
03:30 - 07:00: Key Concepts in ICT The chapter emphasizes the importance of communication in academic settings, particularly in group assignments. It stresses that students must notify their instructors upon being admitted to a course to be properly assigned to a group. It notes that students will not know which group they are a part of or who their group members are until they make their initial post in the course forum. This highlights the procedural aspects of course management and student responsibilities in ICT contexts.
07:00 - 13:30: Evolution of Computers and Internet The chapter titled 'Evolution of Computers and Internet' seems to contain a transcript which speaks about the logistical design of posting interactions, possibly in an online or educational setting. It implies that the ability to post or not post can affect the outcomes or marks others receive, indicating a collective or shared assessment model. This suggests a focus on how technological interactions have evolved in terms of learning and community engagement. However, the transcript provided is not very clear or detailed about the broader themes or specific historical points of the chapter.
13:30 - 25:00: Current Trends in Technology Most participants have completed the initial sections (one, two, and three) and are working on the main part of the assessment, which involves research and evaluation. The conversation will center around 'I one' and other issues can be discussed later individually.
25:00 - 37:00: Ethics and Societal Impact The chapter titled 'Ethics and Societal Impact' discusses the broader perspective on key concepts related to ethics and societal influences. It emphasizes understanding the basic connections between various topics and how they align with current group projects. The chapter aims to broaden perspectives by examining important concepts such as infrastructure and the underlying drivers within the context of ethics and societal impact.
37:00 - 45:00: Contemporary Issues and Conclusion In this concluding chapter, the focus shifts to contemporary issues in the realm of healthy, green, or cloud computing. An interesting discussion emerges around 'Green Computing', a concept not widely heard by the audience. A captivating tale is shared about two individuals who embraced this idea, worked on its application and made recommendations, culminating in a well-deserved promotion for their innovative contributions.

00:00 - 00:30 okay so good night everyone Welcome to our third um session and tonight we want to just cover or make you aware of some of the historical as well as contemporary issues as it relates to I see
00:30 - 01:00 teas but before we get there let me just one two housekeeping issues if you join the course late not your fault you had overr Etc you ready should let me know that you'll been in you don't just hang there and War two cases people going complaining I didn't put them in a group and all kind of say it's not my fault it's not your fault creating creating unnecessary drama so
01:00 - 01:30 you really at a matter of courtesy should let me know if you were ready on override and you finally got admitted to the course then I will be able to put you in a group but all persons to the best of my knowledge would have been placed in a group um so and let me remind you unless you make the initial post you will not know which group you're in neither will you know who's your group members or team members until you met that post and
01:30 - 02:00 wait at least 30 minutes it's deliberately designed that way for you to do your interactions the single post or individual post will get you your mark so that would affect others so if if a person doesn't post it w affect the other people who post for the single components right so let me a little concern
02:00 - 02:30 so I from observation most people have already completed sections one two and three and well on the way for the meat of the assessment which is the actual um research and evaluation any other issues all you talk to me after all right so we're going to focus on I one
02:30 - 03:00 two slides is just a repeat of what we said before but basic to show connection to how the topics are laid out and then one or two it may give you ideas for the current group project again broadening your your perspective so we're going to look at some of the key Concepts that you require to know like like C infrastructure and what are drivers and
03:00 - 03:30 then we're going to look at the actual um contemporary issues in terms of um healthy or green or cloud computing interestingly enough for green comp Computing youall heard about Green Computing no all right want two persons captur this concept and went to work and applied it or made recommendations and got promotion and
03:30 - 04:00 heading a particular department or section just from being exposed to it so who knows there are lots of success stories from these computer courses and as I said before you know some people say they don't like it and but if you take it to heart you may find that it may provide opportunities for you this one the one that some people may do next micro Computer Applications and those who move on to Mis those three
04:00 - 04:30 those three courses tend to offer lots of opportunities that you probably didn't see at first so we want to explore how the icts have been used in Broad areas from a technical perspective and now how it's been incorporated into the behavioral um Sciences so before ICT was basically related to like computer
04:30 - 05:00 Saints and people who doing research or management Saints as the case may be no we have brought in that to include the behavioral and so some of you are doing psychology economics sociology Etc and you're going to find that ICT ICT sorry they're now playing a significant part in driving the operations and Def findings in these areas so as we prog you're going to find
05:00 - 05:30 that it might be difficult to identify any aspect of our existence that is not touched in some way by information communication Technologies so let's begin here you need to know the difference between data and information um usually people refer to the two terms as the meaning the same but in it they're not all right so data is what we will call the buil is used as building block for information data by
05:30 - 06:00 itself is raw it may not carry any meaning especially to persons who are not familiar with the construct but if you take the data and you process it then it leads to what is called information so information is the processed data that you use so when you apply to UI you had
06:00 - 06:30 bits of data on your applications form now ask you for your name you ask you for your address your qualifications etc etc now over a period of time along with your grades from this course or that course assessments Etc bits of data will be combined process and you may get what we call a transcript um information may be processed and sent to the Ministry of Education or whereever
06:30 - 07:00 indicating that the the registration levels have dropped or increased so that taking what is there the data and processing it to give you information so information reveals meaning all right data is vague but information gives information or meaning to all who will interact with that information and please note that information is required for good decision making so all of you
07:00 - 07:30 whenever wherever you need information to make a decision and therefore the information must be accurate relevant and timely so you don't want to go into the bank for example and ask for the balance on your account and they told you tell you to come back in two or three weeks but then a lot would have happened or you don't want to to make medical decisions on some on data that
07:30 - 08:00 wasn't updated for the past five or 10 years so once your data SL information is accurate relevant and timely it means more likely that your decision making is going to be at is Optimum the other thing you need to know is that computers are powerful and they scare you for life how they scare you these are the
08:00 - 08:30 areas of application so the speed is important trillions of instructions per second and the time it takes you to Blink A system can perform trillions of instructions maybe more with the development that we've had in recent times computers are powerful or offer advantages in terms of the ability to communicate communication aspect so each person in a workplace don't have their
08:30 - 09:00 own printer for example but they will have a shared printer across the network so IP stands for the input processing output and storage operations that are more or less integrated and made easier for communication purposes computers are known for accuracy all right there's a level of consistency now that wasn't there before so they had lots of mistakes Etc but the accuracy has
09:00 - 09:30 basically improved to the point that almost everything that we do relies on computers so here here will gigle g go garbage in garbage out any person ever slap a computer for giving you the wrong output or smash the device this but it really is not the device fault whatever you put in and if you put in garbage you can rest assure that you're going to get garbage coming to you you can only
09:30 - 10:00 process what is entered um and based on the rules that are applied in terms of reliability systems today have low failure rate right there was a time when the computers have crash often most of you probably would know that because you are more or less spoiled now with systems that are relatively um stable so low failure rate has dropped significantly and now we have a high level of reliability to the
10:00 - 10:30 point that we basically rely on these computers to drive our existence and the last one would be storage the ability to store huge volumes of data all right slash information so we will be scared quote unquote for Life by the effects of computers
10:30 - 11:00 all right so on the right you have some images any of those look familiar now people I I tend to do this not that I old right but it's just to show you where we are so you all remember that had these things what we call the beads used to come on hello right so we don't use those anymore um the
11:00 - 11:30 abocas we and mathematicians um you all only know about L sorry calculators now you ever heard about a log book anybody doing anything in science any science students in here okay so if any gas station wants and ask $50 in gas and give a $100 person pull a calculator we becomes so Reliant now on
11:30 - 12:00 calculators to do every bit of processing for us before there were no calculators they had to use logs you have to use those kind of devices and the last pick shows where we've where we've come now where no matter where you are in the world is almost like a global um village or neighborhood you get instantaneous access now most of you won't know this but a computer was the name of a job that you apply to do so you used to
12:00 - 12:30 apply to be the computer at a business and what was the purpose of that job is basically to do mundane or repetitive task over a period of time so every week your job as the computer was to go in and basically perform repetitive calculations Etc now we have evolved to the point where the computer is no longer a job but it is a device that is used to basically do the same thing all right
12:30 - 13:00 soov the ladies the the astronauts what's the name hidden figures that's the one with the lady had to do all the Computing yeah that's what you used Supply to be so technically she was the computer
13:00 - 13:30 how many of you could have done that in real time calculate navigation and orbit and in real writing writing wrting writing impossible so that's where we are now as opposed to what it was before so poor workers work pretty hard and know you're reaping the benefit of that um sacrifice previously so you need to understand and please
13:30 - 14:00 make a note maybe this was from last lecture the definition of a to some extent what is information communication Technologies you need to know and basically um if you remember from last lecture how you use your digital Technologies the tools how you communicate how you net workor to access to store to transmit and process information
14:00 - 14:30 that in a nut shs what is ICT and this has Encompass a range of Technologies over a period of time so I will just quickly show you couple of the areas that you may note and maybe one or two of you may incorporate as part of your current group assessment so we've had impa education you have e-learning we have digital libraries you have Smart
14:30 - 15:00 classrooms um Mo mock MC person never heard about that um this is where they have some universities have what we call Mass open open online courses that they offer free freely to the public so you don't necessarily have to pay I guess it's to help a community service you can access several universities and do their courses is free but obviously if you
15:00 - 15:30 want the actual certificate or whatever you may have to do a little registration to access that so we have education you have health health touch electronic Health registration health records data analytics Etc um the last project the government was I don't know was the status of it at this point they were trying to do basically a digital digitalization of the health system
15:30 - 16:00 within Barbados so that it doesn't matter where you go which um facility whether private or public everything is centralized and digitized for easy access for reporting Etc so one of the big areas now is Health informatic or data analytics from a health perspective that is one of the major areas for work is very it's very productive so some of you may end up in that
16:00 - 16:30 area and be able to transfer some of the skills that you would acquire in your social science degree so it is important because it helps to predict um what might be your outbreak where it might be where it might occur Trends patterns Etc so that uh mitigating um factors can be considered Banking and
16:30 - 17:00 finance oh that is headaches for some people how many of you prefer the face t- face transactions to going to the bank we have all other issues the security concerns but most banks now are working shorter hours they're forcing you to use the online services and or smart ATMs that they have available to you most of you have devices with smart wallets Etc
17:00 - 17:30 so the ICT has taken over in online banking and mobile payments to some extent anybody here into blockchain and crypto if you have time we'll get you come and do a little presentation honestly there's one area that I just can't wrap my head around but I was hoping to get someone to come and explain it to you but this is where we're heading towards what we call a
17:30 - 18:00 cashless Society um do you imagine yourself without cash at any point you just tap your finger or clap your hands or whatever and it's paid for it I think they were piloting scenario here with RFID you're going to meet that term and you do your asynchronous where you walk in but you say online where you walk in you pack your car and just walk out as you walk in the RF id will scan and then
18:00 - 18:30 send the the toal to your phone or whatever and the payment is made and that's it no Cashers no sales attendance nothing of the sort it's just walk in and walk out and if you saw during Co in I think Dubai you have this drivethru where you drive in and you pick along different floors or levels without any interactive with any person so that is where we at
18:30 - 19:00 as far as the banking and finan is concerned you have business and commerce e-commerce digital marketing um well there no try to get rid of work from home again forcing most people to return to the office it's neither here or there we may end up doing that again so you have interviews for a job banking appointment you don't have to physically go you can
19:00 - 19:30 use tools like zoom and teams to do the collaboration governments Public Services we now have e governance we have the digital ID which which was a big issue couple two or three years ago how many of you have the new ID people kicking a fuss but I can take your phone and find more information about you that be a bit more critical
19:30 - 20:00 than the actual ID that you have such is life and then we have um transportation and Logistics we have driverless Vehicles now that's one of my next time travel I want to get one of those getting one of those just driver on before the driver y saw them Clips would you do it why not
20:00 - 20:30 got be adventurous online ticket ticketing system how use Wiz you know know Wiz or our local GPS as opposed to Google I don't like I don't know how people use Google who is put in middle of the road until you reach your destination w w a z just you must have
20:30 - 21:00 data but WS is very accurate it always place you right at the the door or the step of wh you're going but that's just my opinion sobody saying something so yeah you have automated Traffic Systems the traffic lights Etc being controlled by icts um there was a time you come to a traffic light and you can actually wait five minutes for the sequence to to
21:00 - 21:30 be completed that don't really happen now that has improved a lot significantly as soon as you get there based on the traffic flow you either get go ahead or or you have to wait few seconds before you move agriculture we're looking now there are places that use Junes Etc to manage the agriculture um irrigation and pest controls Etc so don't matter where you think of no
21:30 - 22:00 matter what you think of icts will be in effect so your assignment May touch on one of these areas here as Ai and information may affect the outcome make a note look for look regulations
22:00 - 22:30 and policy ICT because of the enormous uh reach of ACS it is necessary to have regulations and policies in place so government must play a role as well as International bodies in regulating the use of these um tools to avoid misuse Etc you must have laws we have rules we have laws here we have um laws governing
22:30 - 23:00 the the online abuse cyber bullying those kind of things which are necessary people have this perception that once is on the net or you can go online and do as they please it doesn't work so not anymore so you must have in place policies and rules there in educ for example there's a rule or law or
23:00 - 23:30 policy that schools must use ICT or have ICT as part of their curriculum so all of you came through our educational system and at some point you would have had to done done you would have done a course with some kind of technology in it correct hello you can't go through UV now because you have to do discour as part of your program so
23:30 - 24:00 where the ICT start the Genesis basically the internet and the worldwide web uh there was something called arpanet so make a note of that term ARA net so some of you might need to do additional research on that down the road um so this was where about four five scientists got together together and develop a system that they can
24:00 - 24:30 communicate with each other in case there was a natural disaster or war and we have evolved from that from way back in 69 to where we at now in terms of hold the internet is actually used for uh communication Etc so the art pro project was a a simplistic um Network few computers that would allow
24:30 - 25:00 communication across several States this was in the US and in case it was a as it said a natural disaster or war and it has evolved the concept has evolved to where it's at right now in terms of computing so the revolution basically started there where these scientists were quote unquote Forward Thinking and now we have a whole set of whole set of actual services that
25:00 - 25:30 would have developed for from the internet from that concept so the World Way web as you know it is one of the services from the quote unquote internet the internet is like the network www worldwide web would be considered as one of the services offered by the internet or you more call it a web which is basically a collection of pages that you access through your browser from time to
25:30 - 26:00 time in terms of architecture architecture speaks to principles or guidelines or rules that are used by organizations or Enterprises to basically manage how they process and interact their resources so they were
26:00 - 26:30 five main architectures and era or what we call Generations so we started with the old ones somewhere from the 1950s so you would have heard about the um inia where and you stand to see if you watch black and white um movies the very old ones you will see a computer that probably stretch from here to IT
26:30 - 27:00 services huge um systems that were used to do the Computing in that time frame now you ever heard the term debugging any person here the it outside of discourse so you ever heard the term debug so debugging debugging means to get rid of Errors right the term came from the fact that those old systems every time you wanted to do a process or
27:00 - 27:30 job you had to do a series of wires wiring so one day a actual bug was caught in the wire and they couldn't get the job done so they had to take down all of the wires to get the bug out hence the term debugging and you're going to find out a lot of the terminologies that we use in a CT are basically um simple things that would have happened in in in in for from the experiences so we had the general
27:30 - 28:00 purpose here and then you went to personal computers from the 1980s or so then it started to present opportunities to individuals to have their own quote unquote computer now how many of you have a PC at home still one person two so for some people this is your computer
28:00 - 28:30 right smart device my first my first computer was something called a 286 and guess how much memory I had two two megabytes of memory and if you were Rich you were considered rich if you had a 486 so I had a 28 a 38 and the 486 which was about six or so megabytes you know now we into
28:30 - 29:00 gigabytes and yes you felt good having your own computer where you can do um some task on your own but in that 80s that personal computer era um era that is where we started to see a lot of software development at so um not word there was something called Word Perfect Lotus one to3 so so you had a proliferation of personal software that
29:00 - 29:30 people can actually use at a personal level for their purposes then we moved to client server people started to develop where instead of having the individual devices you can Network them or have a collaboration so we have this um thing called C so each system on the network would have been considered as a claim how many people watch football illegally when they say illegally you
29:30 - 30:00 don't pay established Services you you look for links online peer-to-peer Network so some are watching the football game from someone's computer but they're all linked up and what we call a pair to pair and again you're going to deal with these configurations when you go to your um asynchronous module so that era just after the personal computers the client server technology concept started to te root
30:00 - 30:30 and then we mve into the Enterprise Computing era where businesses started to realize the the the significant benefit of computerization within their organization how to use technology as a resource or strategy and so they started to integrate different aspects of the business using the internet and various applications available and now we are at
30:30 - 31:00 more or less what is called the cloud computing which most of you are familiar with you use the cloud to access Services Etc and I'm going to deal with that shortly as a separate slide so those were principally the quote unquote the distinct stages of architecture as far as and then in between there you have some what we call the iot think I told
31:00 - 31:30 you to remember research that iot internet of things where Bally almost every device that we have well ples Etc they are now designed to be part of this quote unquote internet um networking concept so what are the emerging trains in in ICT let's look quickly at cloud
31:30 - 32:00 computing and you will note cloud computing is simply the delivery of Computing Services right in the internet so the internet is seen as quote unquote the cloud and when we talk about cloud computing then we're talking about the delivery of Computing Services over the Internet so that is done the acquire several
32:00 - 32:30 benefits so these services are normally offered as a service so you have the s s which most of us use or consume so those are things like see email and customer resource management and collaborative effort and enterprise resource planning Erp so most of you use email you don't have your own email but you use the
32:30 - 33:00 email and you store your data in the cloud so to speak as a service all right so it may come well in this case we student you it is C on courot free but nothing is free really you have to pay for it at some point some people may have their own private um storage cloud storage uh where you pay a monthly fee or whatever the case because you may need that additional space to store your work we can also have Cloud Computing
33:00 - 33:30 Services as a platform so there are people or companies who specialize in app development or Provide support as far as decision making is concerned do streaming online Etc web development so the p is used to build on right so companies depending on the size May Outsource to these individuals because of the expertise that they offer
33:30 - 34:00 and then you have the infrastructure as a service a AAS which allows you to migrate so when companies want to um expand or move to a better platform sorry better service Etc then they will use the A and all these are offered at very prices depending on location to companies so I ideally these are the benefits of cloud
34:00 - 34:30 computing I think we asked this last week with out internet what happens with cloud computing you run yourself in serious problem so there are lots of risk associated with cloud computing you can be H you can have unauthorized access um if the vendor go Rogue or whatever the case may be you may have legal issues developing and if there is no more internet what happens you can't
34:30 - 35:00 access we've had instances in recent times where for whatever reason um people's private details and are public pictures Etc so these are all risks that are associated with cloud computing artificial intelligence well that is currently your topic and is currently being used now what we call machine
35:00 - 35:30 learning um where you train Based on data to develop algorithms so that is how based on your search profile or your browsing history or pattern you're able to see certain things appearing in quote unquote your your feet so yes artificial intelligence is my thing is I well it seems to me that artificial intelligence is trying to to establish your as the intelligent
35:30 - 36:00 the aexs and we as human beings we are being pushed back to what we call the Stone Age so you don't have any intelligence you have to come to me and that's basically what is happening and we are actually given into it because we know rely exclusively on technology and devices to do everything for us am I right or wrong
36:00 - 36:30 so in essence we become quote unquote lazy because it can be done easier for us by some device or program artificial intelligence is taken over and eventually there's going to be you all remember um SM somebody I Robot you remember I Robot that's going to
36:30 - 37:00 happen internet of things don't say that this confusing it is because of the proliferation of um physical devices that are now to um be attached or connected to the internet or other communication networks so last I told you that you can actually start cooking washing Etc from your car you can monitor your security systems
37:00 - 37:30 from wherever that's basically what the Internet of Things is all about any device anybody anywhere anytime anyhow instantaneous access is basically what is driving that vir
37:30 - 38:00 Aug reality versus um you have to read books on history you're actually there are several schools and University that are piloting this pilot piloting dat a level of Engagement interacting with the system for example the body or a car whatever using
38:00 - 38:30 3D anybody ever had a know was a view Master those a view Master you know you go and pay what's the price for um Olympus so watch [Music] 3D $24 22 so that has something called a view Master we were ahead of our time so you put this circular film with slots and you
38:30 - 39:00 put that's what we used to call that was r3d how many people know what I'm talking about let just see yeah so this now virtual VR AR has been Incorporated in all significant aspects of our um social interaction I again with engaging
39:00 - 39:30 results and then the blockchain um yeah so you have you're trading in it engage trains in infrastructure you need to know some of these technology is supposed to be fast smaller I know we can debate if it is
39:30 - 40:00 cheaper is technology to to you cheaper now than before I know television sell pretty fast um ubitus access meaning anywhere anytime anyhow how many of you ever had any of these flash Joys are here and you look familiar who had the one here trust me some of these look very strange to me
40:00 - 40:30 too and then down here any of these mobile devices what about here you know what are these those are what we used to call floppy disc used to store buy those if you have a a program to install by about 15 or 25 and you put them in one after
40:30 - 41:00 the next so most systems they don't have air drives or D for that matter now I think most of you probably be familiar with this one down here the trainer half floppy small one correct you know so Min miniaturization not everything supposed to be going small and then we had this big debate recently we the point where we were our smallest
41:00 - 41:30 and now we're going back up the the the the ladder where people prefer big phones right that is debate recently um so you find out people now have a larger phone and they prefer to walk with it in their hand before you will get a phone you want it small to put in your pocket or something but people now walk with their phones in their hands um it's a social thing and
41:30 - 42:00 it creates it helps to add to the notion that you have a connection with your phone I want to say you're in love with it because then there might be some people like that but you have this connection that you actually so Min so everything is being made on a small baller or minist skill and that is now is the trend basically in almost any
42:00 - 42:30 aspect of um our social interaction especially in manufacturing almost every um device has gotten smaller and smaller you ever bought a pack of chips or a bag of chips and then it feels like you have lot you opening only two chips in there full of air we going to come to a concept
42:30 - 43:00 shortly called nanotechnology and these are topics that I'm just giving you that you need to just read upon you know I have to know everything so this is what we call drivers so there's something called Mo's law which speaks to the processing power so
43:00 - 43:30 it is clear that the more transistors you have or ever saw inside of a a computer the the motherboard the more the denser is in terms of transistors or what we call the integrated circuit the more powerful it is and the law law is that it doubles every two years um that has changed in recent times because how many people people Chang phones now every six
43:30 - 44:00 months now for example if you have how many people have a s s23 s24 s22 I ain't going to Apple what's the latest Apple are are you 16 Pro 16 Pro how many people have the 16 Pro don't be as shamed so was the other one above that so if I have a s23 why would I want to
44:00 - 44:30 upgrade to s25 in a year when the when the differences is very minimal some people do it to keep up or exhibit a particular style but before the computing power was alleged to have doubl every two years that has dropped significantly and I sure is more less than than um two years now we also I think I have it here I have this
44:30 - 45:00 video online nanot technology so I don't think you're it was supposed to play here but you're not going to say but what is nanot technology it it speaks to dimensions of what we call tolerance so the best way that I can explain is get to technical how many people ever fright egg well assuming you know the frag egg do you put salt on egg how do you
45:00 - 45:30 put it on you take salt you sprinkle it right and then when you're eating it you realize that one piece taste it got in the whole bottle of salt and then other is none so how do we deal with that to make it a little even the distribution of the salt even what do we use now use your hand still shaker Etc you know to spread so
45:30 - 46:00 nanot technology deals with tolerance so that instead of lumping in one area you have a a greater spread of the technology so nanot technology is being used in production Etc to enable you to get the best quality for example cameras on the production lines Etc so if there's a uh if you're off in the quality buyer whatever it is picked up by the sensors Etc so make a note watch
46:00 - 46:30 the video on nanot technology can I have it up that you can access but it deals with dimensions and tolerance all right so it's supposed to minimize that and it minimizing the tolerance so to speak to quote unquote noise or intrusions you get basically a better experience so all of the devices with the various features that you have like camera Etc will be the result of
46:30 - 47:00 the application of nano technology and then you also need to take note of the law of mass digital storage which says again storage capacity would double almost um yearly or every two years so now you before you can go and buy a flash drive 2 gabes it was a minimum size now they have about 16 you have to pay maybe $30 $25 depending
47:00 - 47:30 on where you go so what are you going to put on that flash drive you may you want to submit an assignment and you have to buy a 8 gig or 16 gig flashight just to a Word document and you still have lots of space available so might as well utilize it in other forms store your music um videos Etc then the other one that you need to be aware of and know I said be aware of
47:30 - 48:00 so it would be good not to delve in but you just want to understand what is in this case Metal's law what is Metal's law referring to um Network economics or effects so he discovered that there's a value in network the more people you have on a network the more beneficial it becomes
48:00 - 48:30 so how many people here on network sorry on Facebook for example and you can go on the things like Instagram the social media platforms Etc the more you have the quote unquote quality is supposed to be better or the the benefits of that is supposed to be better so I think they use the formula and all right you can't move from here n n
48:30 - 49:00 brackets n minus one brackets two so if you have two telephones for example that will make one connection if you have five you end up with 10 and 12 will give you 66 if you use that formula you don't have to concern yourself with that so the best way to explain Metal's law is using something like eBay what do you find on eBay
49:00 - 49:30 you knowable eBay right so you have buyers and you have what sellers so what will happen if you have more buyers for example more buyers means what anybody doing economics 101 if you have more bares what it
49:30 - 50:00 happen it suggests that there's a demand right if you got a high demand then you might let you see what coming on stream people selling if more people are selling what to happen if you have one seller on campus what it
50:00 - 50:30 happen price might be high right if you have multiple sellers on campus what to happen the price might fall what El will happen that might be beneficial assuming that they're not all in the C together the quality is supposed to improve because you want sales so what you're like to do you're like you to ensure that the quality of what you're selling
50:30 - 51:00 is good right so metav is saying that you get the same side effect more buyers make a platform better attract more people and more sellers will so that in essence demonstrates to some extent what M's law was basic saying so the more you have the more likely you're going to see Improvement and quality from the perspective in which you're operating opting um the only down for that is if
51:00 - 51:30 everybody decide to to to the sellers for example get together and say you know what maybe all do a minimum or whatever the case may be but usually that won't happen in more situations all right so what are the Contemporary issues take note we don't not going through all these in detail the digital device we spoke about that early on which is the equity of access to
51:30 - 52:00 technology dep on where you are we spoke about privacy data protection last class uh cyber security we spoke about misinformation disinformation and ethical issues I saw an interesting click just before it came to class involving AI if I find I'm going to post it for you to to consider all person will have access to
52:00 - 52:30 it so it shouldn't be advantage to one group ordinary but a is very serious I mean really really serious and some of you be I don't know if you realize there's a difference in terms of how your laptop or computer is functioning recently all right we leave it at that interesting development how many of you have variable
52:30 - 53:00 technology apparently now there is a piece of device for every part of your body what we call variable technology all right so you can you will zoom on the slides but variable technology is basically the or the analysis and application of the various devices so some people may have a series
53:00 - 53:30 of tattoos it may look to you like tattoos but actually they might be uh digitized in that they're able to do some form of communication depending on the purpose of the tattoo so you may see something here that looks like a tattoo but it might be actually for a person having TR problems and their ability connect it to um an insertion that allows them to speak or communicate via um a particular device um I try her not to your contact
53:30 - 54:00 lenses any person here with air glasses so what the benefits of varable technology is that depending on the situation of the individual it may be communicating information so for example uh from a medical perspective
54:00 - 54:30 you might be feeding real time data to your your doctor or whoever for feedback analysis monitoring so to speak some people use it for good intent others use it for bad intentions all right you don't know um the AI glasses there are some U pens for example with camera in it people have cameras built into their buttons or
54:30 - 55:00 what they wear for various reasons all right so this is what we mean by varable technology so um you don't have to go to be measured in terms of you know what size you may want to wear for dress or pants or whatever you may have a device that when you walk in if it is the the actual environment can actually pick up these measurements and suggest to what
55:00 - 55:30 will fit you now we saw these things before in cartoons they're actually happening um the headpiece the augmented virtual reality Etc I refuse to touch on implants but we all have different types for different reasons um shoes there are some of us that may have a difference balance problem you can
55:30 - 56:00 actually get shoes that do automatic adjustments the devices built into the shoes that allow you to get the adjustments to ensure that you avoid any damage or injuries to yourself um as I said before there are some tattoos that act as built in mics or microphones for people to do communication and for voice commands all right so let's get to some
56:00 - 56:30 of the interesting Concepts ethics and Computing this is number one I think I have a PDF on each of these and one or two videos as well so basically what are the assets involved in Computing computer ethics do you fall into the category of um abusing your computer computer abuse so bullying do
56:30 - 57:00 you use it for Crime you have a ha system any person ever access somebody device before Authority on authorized access when they were sleeping you you you went you took the phone and took their finger and tried to do a biometric none of you start of you look
57:00 - 57:30 guilty um intellectual property so toor number's work you should credit credit is youm policy that you were supposed to read will also guide you so the question is asked these things do you you have a heightened sense of um ethical
57:30 - 58:00 concerns would you cheat now would you WR to Pirate let me go and purchase a copy do you have that mindset uh there was a time where you can go by go down to and buy um three CDs for $10 the music on it favorite music um know that still happens but can you get your friend to give you a plasure with some of the latest hits Etc without actually paying for those things now we tend to get away with a lot of
58:00 - 58:30 those in the Caribbean typically but in this in other of the developed countries it is not something that people play with all right so how would you feel if people take your work whether is um art clothing whatever and use it and profit before you actually benefiting from your work so take note and do a little reading on the essay and Computing aspect we can't
58:30 - 59:00 speak about the societal Empire of it um how harmful has it been to us as individuals as the society with the Advent of the social networks so most of these you touched on in last lecture and some of the ter that should be a hint to
59:00 - 59:30 you so as students for example you have the advantage of the impa by using now e-learning before there was
59:30 - 60:00 everything in the book resources now everything is presented to you presented to you on a platter and you allegedly you should get more productivity in the workplace decision making easier it is also faster of Labor or use less paper is being used you tend to
60:00 - 60:30 our emment it becomes a bit more difficult to do these things because the thing called employee surveillance so where you were do they have cameras on you and do you feel comfortable working with cameras on you so some people say as an invasion of privacy the employer might take think otherwise that it is a way to safeguard and to Ure that people do what they're
60:30 - 61:00 supposed to do especially in situations where death is possible the downside of that is that I don't know if you want to if you agree or not the societal impact has made most of us robotic in nature we act more like robots now um there's no the social skills basically has disappeared or D up so we can't interact with each other we have
61:00 - 61:30 been so um influenced by the technology that we are more or less roboted in our attitudes we spoke ear about the PC is the PC dying or is it dead or will it ever go away what do you think
61:30 - 62:00 more comment it may eventually may be another 50 years or so but there are lots of businesses and organizations um individuals who still rely on PCs for most of their Computing
62:00 - 62:30 um processes so all of our Labs currently have PCS do you envision the lab before PCS anytime soon some of us have replaced as I before of the more powerful smart devices that we have now so what used to occur on a PC you can actually do now mobile anywhere anytime you don't have to be fixed in one location healthy
62:30 - 63:00 Computing you need to Noble ergonomics I know half of us if all of us would have been don't practice this some extent um you're at home how do you how do you use your laptop you're your bed S Bar on your belly whatever the case may be you practice ergonomics so we were supposed to be when you're in
63:00 - 63:30 the labs Jo these tutorials monitoring how people use system if they're practicing ergonomics so you sit um posture Etc we're going to have a serious problem in a not too distant future and maybe that may be another opening for a particular type of job that can deal with individuals who don't practice ergonomics and there's one called the CR net you know it's CR
63:30 - 64:00 net CR net so 90% of people walk around and they in their phone so after while they develop a curve here caror any person to caror to get straighten out
64:00 - 64:30 Green Computing is the manner in which we build use and dispose of computers based on environmental concerns this is the formal definition of ring Computing so you have green use Green Design Green Disposal Green Mar manufacturing there's something called Green banking there's green manufacturing and the list goes on I
64:30 - 65:00 even think there's green education so in green banking they don't I don't know they still say statements and things V mail yeah so green bank is supposed to eliminate all of that you get a digital statement most people have already eliminated so Greening speaks to the Technologies and Manufacturing who you
65:00 - 65:30 use in this sport so you don't really dump in gullies anymore or put them in the outside for the garbage TR to pick up Etc um if you have a printer you don't dispose of it you just get buy a new cartridge or whatever the case may be and install if you have a old system that you don't want to use rather than dispose of it you refurbish it to some extent by wiping it off your personal data and you give it to someone else who can use for um limited
65:30 - 66:00 processing um Powers so the Green Computing encompasses social environment and the economic aspect and ultimately it's supposed to be able to um have a sustainable environment which is um to everyone's benefit so if you don't dispose properly
66:00 - 66:30 properly you're going to carnish the environment and you also run the risk of increasing the economic cost because there might be out breaks or the the the magnitude of Labor required to clean it up might be significant so the that's basically what Green Computing is referring to so as I said before one two persons took this concept and went back to work and got rather creative and
66:30 - 67:00 Innovative and now there are supervisor or heading in that section and I would have saved the company that the organization that they are quite a bit in terms of the policies that they've implemented it may seem a bit difficult at first but once you adhere to it then you get the best of results and the last thing I want you to take from this lecture all persons in this course must know at least one or
67:00 - 67:30 two technologies for people with disabilities or special needs and therefore I will tell you you have assisted technology I would expect coming out of your um your group project if possible um this aspect all person in this course must know at least one or two technologies for people with dis abilities or special needs so how it can offer them
67:30 - 68:00 Independence how it can improve their quality of life how it helps them to participate or be active now I'm sure some of you may not know it but there one to persons who may be your group and you will not know because of the technology they're able to act and collaborate with you um quote unquote
68:00 - 68:30 so that brings me to the end of the session um pause recording here
