The most common twisted pair cabling.
T568A and T568B Termination
Pin assignments from EIA/TIA-568-B standard.
Eight conductor 100-ohm balanced.
Twisted-pair cabling.
T568A and T568B are different pin assignments for 8P8C connectors.
Assigns the T568A pin-out to horizontal cabling.
Many organizations traditionally use 568B.
You can’t terminate one side of the cable with 568A and the other with 568B.

Dual link; 7.4 Gbps (HDTV at 85 fps).
Three types:
DVI-A, DVI-D, DVI-I.
Lightning
Apple proprietary.
8-pin digital signals - iPhone, iPad, iPod devices.
Some advantages over Micro-USB.
Higher power output for phones and tablets.
Can be inserted either way.
Simpler design, more durable.
Thunderbolt

20 Gbit/s total throughput.
Mini DisplayPort connector.
Thunderbolt v2:
20 Gbit/s aggregated channels.
Mini DisplayPort connector.
Thunderbolt v3:
40 Gbit/s aggregated throughput.
USB-C connector.
Maximum 3 meters (copper).
USB
Universal Serial Bus.
Simplify connections.
Printers, storage devices, keyboard, mouse.

Full speed: 12 megabits per second, 5 meters.
USB 2.0
480 megabits per second, 5 meters.
USB 3.0 - SuperSpeed
5 gigabits per second, ~3 meters.
Standard does not specify a cable length.
USB 3.1
Universal Serial Bus.
USB 3.1
Released July 2013.
SuperSpeed+.
10 Gbit/sec.
USB 3.2
Universal Serial Bus.
Released September 2017
SuperSpeed+ over a USB-C connector
10 Gbit/sec and 20 Gbit/sec
USB-C
Universal Serial Bus - C.
USB has a lot of different connectors.
USB-C replaces all of these.
USB-C isn’t necessarily USB 3.1
The cable must support the function.
USB 3.1 speeds.
Power delivery (> 7.5 watts).
Alternate mode (additional data wires).
DB-9 serial cable connector
Different sizes, A through E.
Commonly used for RS-232.
Serial communications standard.
Built for modem communication.
Used for modems, printers, mice, networking.
Commonly used as a configuration port.
Serial console interface.
SATA
Serial AT Attachment.

PATA
Parallel AT Attachment.
Originally called Integrated Drive Electronics (IDE).
A Western Digital invention.
2nd generation called EIDE (Enhanced IDE).
The evolution.
Promised faster speeds.
From 16 MB/s through 133 MB/s.
Additional devices.

Fast SCSI, Ultra SCSI, Ultra Wide SCSI, Ultra2 SCSI,
Ultra3 SCSI, Ultra-320 SCSI, Ultra-640 SCSI,
iSCSI (SCSI over IP)
Parallel and serial options.
Adapters - DVI to HDMI
DVI-D and HDMI are electrically compatible
HDMI is backward-compatible with DVI-D
No signal conversion required
No loss of video quality
Adapters - USB to Ethernet
Some laptops don’t have an Ethernet connection
Convert USB to Ethernet
Adapters - DVI to VGA
DVI-A includes analog signals
Backward compatible with VGA
Only 640 x 480 is officially supported
May only need an adapter
Analog to analog
VGA to DVI digital will need a converter
Check your interface specifications
