Computer cables form the connections between computer systems and their
peripheral devices. They are physical implementations of interface
standards for transmitting data between computers and peripherals such
as keyboards, display devices, mass storage units, and printers.
These standards, developed over the years by various commercial firms
and standards organizations, specify the usage and signal characteristics
of each wire in the cable. They also specify data transfer rates,
connector specifications, and maximum cable lengths.
Looking at a typical personal computer, one sees a jumble of cables.
For instance, short IDE cables, serial ATA cables, or SCSI cables attach
computer motherboards to their disk drives. Analog cables are used
to connect computer audio devices to speakers, microphones, and external
audio systems. 15-pin VGA cables or DVI cables connect computers
with their display monitors, while Centronics parallel cables are often
used to connect computers with printers. However, more compact USB
cables and USB interfaces are now standard features on many printers,
scanners, and digital cameras.
Early personal computers used a 5-pin DIN keyboard cable connector; IBM
PS/2 keyboards used a 6-pin mini-DIN connector, and many modern keyboards
interface via a USB cable. Early PCs used a 9-pin serial mouse
cable connector; PS/2 models used a 6-pin mini-DIN connector, and today
a computer mouse often interfaces using a USB cable. Because of the
many cable and switching techniques that are used to connect keyboards,
video monitors, and pointing devices, the computer cable industry has
coined the acronyms KVM cables and KVM switches. These
terms refer to products that interface keyboard, video, and mouse devices
in various ways.

In a broader sense, computer cables include Cat5, Cat5e, or Cat6 network
cables with RJ-45 connectors, which link computers together via Ethernet
hubs and repeaters. For large network installations, professionally
installed premises wiring, consisting of copper cables or fiber optic
cables, is run through walls and between floors of commercial buildings.
