35
_ allows you to connect video sources to your display carries audio as well
DisplayPort
36
_ is a specification defined by the Video Electronics Standards Association (VESA) -Means its not proprietary, manufacturers don’t have to pay a licensing fee to put a display port on their device Packetized data transmission Compatible with DVI and HDMI
DisplayPort
37
_ is a digital video audio interface | replaces analog standards

Thunderbolt
39
USB
Universal Serial Bus
40
USB _ was introduced in 1996 as version 1.0 At that time there were two variations - Slow speed that operated at 1.5 Mbps over a distance of 3 meters - Full speed that operated at 12 Mbps over a distance of 5 meters Physical connectors - Had type A that connected to computer - Had type B that connected to device
1.0
41
``` USB _ was released in 2000 Introduced modifications to USB package Speed was increased to 480 Mbps over 5 meters Connectors • Type-A • Mini A • Micro A • Type-B • Mini B • Micro B ```
2.0
42
``` USB _ was released in 2008 Operated at SuperSpeed with operated at 5 Gbps over 3 meters Implemented full duplex communication Connectors • Type-A • Type-B • Micro B Superspeed ```
3.0
43
``` USB _ has a 24 pin USB connector USB 3.1 • SuperSpeed transfer mode (5 Gbps) • SuperSpeed+ transfer mode USB 3.2 • Two new SuperSpeed+ transfer modes • 10 and 20 Gbps throughput ```
C
44
``` _ cables are transfer data between devices using Serial communication protocol -That transmits data one bit at a time Primarily used -For lower bandwidth devices over long distances Communication standards -Varying transmission standards ```
Peripheral
45
An example of serial communication is _ serial communication
RS-232
46
_ Serial communication is communication between Data Terminal Equipment (such as a computer terminal) and Data Circuit-Terminating Equipment (a device such as a modem)
RS-232
47
_ standard defines Signal characteristics from electrical standpoint like the timing and meaning of the signals Physical characteristics like the pin out configuration of the cables
RS-232
48

eSATA
55
SCSI
Small Computer System Interface
56
_ is Implemented as a parallel interface It meant it can have multiple devices supported per cable -8 total in the original release, increased to 16 in later revisions ``` Internal cables -50, 68, and 80 pins External cables -50 and 68 pins -Shielded/unshielded ```
