CompTIA A+ (220-1001) 3.1 Cables

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

Category 5 wire, a TIA/EIA standard for UTP wiring that can operate at up to 100 Mbps.

Cat 5e

Category 5e wire; TIA/EIA standard for UTP wiring that can operate at up

to 1 Gbps.

Cat 6

Category 6 wire; TIA/EIA standard for UTP wiring that can operate at up to

10 Gbps.

Plenum Cable

Fire resistant and non-toxic; it must be used when wiring above ceiling tiles. PVC cable cannot be used to wire above ceilings because it is toxic when burned.

Shielded twisted pair

cable consists of twisted wire pairs that are not only individually insulated, but also surrounded by a shielding made of a metallic substance such as foil.

Unshielded twisted pair

Most home networks use UTP cable, which is most susceptible to interference.

568A/B

?

Fiber Optics

Bundles of long strands of pure glass that efficiently transmit light pulses over long distances. Interception without detection is difficult.

Coaxial

Single copper wire cable surrounded by plastic used in wired networks

VGA

The VGA translates binary-coded information (0s and 1s) into the color combinations required to make up an image on your computer screen.

HDMI

The most popular digital graphics transfer

protocol. Used to plug into newer monitors,

TVs, and projectors.

Mini-HDMI

used to transfer high quality video/audio from smaller devices to larger screens

DisplayPort

a port that transmits digital video and audio (not analog transmissions) and is slowly replacing VGa and DVI ports on personal computers.

DVI ( DVI-D/DVI-I)

Port that enables digital signals to transmit directly to the LCD monitor

Lightning

Apple Standard 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

A type of connection used to attach devices such as flash drives, scanners, cameras, and printers to a computer.

USB-C

The newest, and most versatile, type of USB connector.

USB 2.0

480 megabits per second, 5 meters

USB 3.0

SuperSpeed: 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.

SATA

Interface for connecting storage devices like hard disks.

IDE Cable

connects drives to motherboard; old, bulky, and slow (think, IDE is so old, soon it's going to DIE)

SCSI

Set of standards used to connect peripherals to computers. Commonly used for SCSI hard disks and/ or tape drives.

DVI to HDMI

DVI and HDMI are electrically compatible

No signal conversion required

No loss of video quality

USB to Ethernet

Used to connect an RJ45 connector to a USB port

DVI to VGA

DVI-A includes analog signals

Backwards compatible with VGA

-Only 640 x 480 resolution supported

-May only need an adapter

VGA to DVI Digital will need a converter
