• 00:30 - 01:00 Bluetooth and hot spots you will also learn about mobile device accessories such as touch pins headsets speakers docking stations port replicators and track pads or drawing pads all right so let's go ahead and talk about some wired communication types and the first one we're going to talk about is the universal serial bus also known as USB so the USB this is a plug and play interface that allows a computer to communicate with the peripheral and other devices USB is the overwhelming
• 01:00 - 01:30 leader in popularity and versatility USB ports can be used for input devices such as keyboards mice and scanners storage devices such as flash drives Optical drives and external hard drives output devices such as printers and multi-function devices and even displays and adapters for both wired and wireless networks are available and a single USB port which is also known as a Root Hub this can connect to multiple devices when a USB hub is connected to the port
• 01:30 - 02:00 and a few various USB connections that you need to be concerned with are as follows the first one is the USBC this is a 24-pin USB connector system with a rotationally symmetric connector so USBC cables and interconnect hosts and devices and they have replaced various other electrical cables and connectors including the USB a the usbb and the 3.5 millimeter audio jack next we have the
• 02:00 - 02:30 micro USB which was superseded by the USBC and this is a very small USB port found on many non-apple cell phones tablets and other portable devices and the micro USB this is considerably smaller than the USB a and the usbb and also the micro USB it is also half the thickness of the mini USB speaking of many USBS which was also superseded by the USBC this is a small USB socket that
• 02:30 - 03:00 can be found on digital cameras external hard drives USB hubs and other equipment the mini USB is much smaller than the USB a and the usbb but it is twice as thick as the micro USB next we have the lightning connector for the Apple iOS system so lightning this is a proprietary computer bus and power connector created and designed by Apple it was introduced in 2012 to replace its predecessor which was the 30 pin dock connector and the lightning connector is
• 03:00 - 03:30 used to connect Apple mobile devices like I iPhones and iPads to host computers external monitors cameras USB battery chargers and other peripherals using eight pins instead of 30 the lightning is much smaller than its predecessor which was integrated with devices like the iPhone 4 and the iPad 2. the male lightning connector is symmetrical so it can be inserted into a female lightning port in either orientation and the male plug is indented on each side to match up with
• 03:30 - 04:00 the corresponding points inside the female port to retain the connection next we have serial interfaces so in years past a device connected to a computer via signal cable plugged into a Serial Port serial means that data bits flow in a line one after the other over the cable serial connections were designed for the relatively low speed of telephone modem communication but were also used for other devices such as keyboards mice and other peripheral
• 04:00 - 04:30 devices serial ports and cables were usually compare to parallel ports and cables or multiple bits flow at once and USB cables have replaced serial cables but it is possible to use a USB to serial adapter to connect to an older machine if necessary next let's talk about some wireless communication types and the first one we're going to talk about is near field communication or NFC so near field communication this is a set of communication protocols for communication between two electronic
