Fiber Cable - ✔✔a glass tube and allows photons of light to be shot through cable.
The fastest form of wired cabling
coaxial cable - ✔✔insulated copper wire; used to carry high-speed data traffic and
television signals
VGA (Video Graphics Array) - ✔✔Standard for the video graphics adapter that was
built into IBM's PS/2 computer. It supports 16 colors in a 640 × 480 pixel video display.
HDMI (High-Definition Multimedia Interface) - ✔✔transfers uncompressed digital
data. Typically, it is used for
connecting high definition video and audio devices.
Mini HDMI - ✔✔The HDMI Type C interface with the same 19 pins as the standard
Type A interface. This compact HDMI interface allows smaller devices to output HDMI
quality audio and video.
DisplayPort - ✔✔a port that transmits digital video and audio (not analog
transmissions) and is slowly replacing VGa and DVI ports on personal computers.
DVI (Digital Visual Interface) - ✔✔Special video connector designed for digitalto-
,digital connections; most commonly seen on PC video cards and LCD monitors.
Some versions also support analog signals with a special adapter.
DVI-D - ✔✔A DVI (Digital Visual Interface) video port that works only with digital
monitors.
DVI-I - ✔✔A DVI (Digital Visual Interface) video port that supports both analog and
digital monitors.
Ethernet - ✔✔a system for connecting a number of computer systems to form a local
area network, with protocols to control the passing of information and to avoid
simultaneous transmission by two or more systems.
CAT-5 Cable - ✔✔UTP capable of 100 Mbps. Four twisted wire pairs (eight wires). My
be used for 10BaseT,10BaseT4, 10BaseT2, 100BaseTX and 1000BaseT Ethernet.
Cat 5e (Enhanced Category 5) - ✔✔A higher-grade version of Cat 5 wiring that
contains high-quality copper, offers a high twist ratio, and uses advanced methods for
reducing cross talk. Enhanced Cat 5 can support a signaling rate of up to 350 MHz, more
than triple the capability of regular Cat 5.
Cat 6 cable - ✔✔A UTP cable type that provides more than 1 Gb/s of throughput.
plenum cable - ✔✔Cabling approved for plenum areas because it has a special fire-
resistant outer sheath that will not burn as quickly as PVC. (14)
Shielded Twisted Pair (STP) - ✔✔A twisted pair cable that has an aluminum shield
inside the plastic jacket that surrounds the pairs of wires.
, Unshielded Twisted Pair (UTP) - ✔✔Networking cable that has four twisted pairs of
copper wire and a flexible outer coating.
568A/B - ✔✔network cable wire standards found in straight through and crossover
cables.
USB 2.0 - ✔✔runs at 480 Mb/s with aa max cable length of 5 meters.
USB-C - ✔✔newer, reversible connector and port that supports charging, data
transfer, and video all in one cable
Thunderbolt - ✔✔a port that transmits both video and data on the same port and
cable. The port is shaped the same as the DisplayPort and is compatible with DisplayPort
devices.
USB 3.0 - ✔✔5 gigabits per second, 3 meters
Serial Cable - ✔✔A type of cable with many different styles of connectors used to
connect a router to an external CSU/DSU on a leased-line installation.
Serial Advanced Technology Attachment (SATA) - ✔✔type of cable inside the
computer connecting the mother board and
internal storage devices, such as the hard drive, CD- or DVD-ROM
