Modern computers are electronic and digital. The actual machinery -- wires, transistors, and circuits -- is called hardware; the instructions and data are called software

Computer Connector

A computer connector is any connector used within computers or to connect computers to networks, printers or other devices. Generally, these connectors have specific names that provide more precise identification, and use of those names is encouraged. Some common computer connectors are D-subminiature, edgecard, Centronics, USB, FireWire, BNC, RJ-11, and various pin and socket designs on 0.100 inch and 2 mm pitches. Most computer connectors are electrical or optical.

Computer Cables

Flat Cables:Flat cables are typically used in computers for internal connections to peripherals. They are also referred to as ribbon cables.

Serial Cables: Serial cables and cable assemblies are used for the serial transmission of data. They support communication protocols such as RS232, RS422, and RS485.

Power Cables: Power cables are solid or stranded conductors surrounded by insulation, shielding, and a protective jacket. These cables are designed for high voltages (>600 V).

Coaxial Cables and Triaxial Cables: Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield. Triaxial cables are specialized coaxial cables.

Network Cables: Network cables and cable assemblies are collections of wires or banded into a single unit with or without connectors.

Ethernet Cables: Ethernet cables and cable assemblies are designed to support Ethernet, a standard protocol for the connection of computers in a local area network (LAN).

Fiber Optic Cable: Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members. Fiber optic cables are used to transmit "light" data

Video Cables: Video cables and cable assemblies are used for the transmission of video signals including monochrome, composite and component color video signals.

Multiconductor Cables: Multiconductor cables contain two or more conductors, each of which consists of a single wire or combination of wires. Cable shielding is placed around an insulated conductor or group of conductors to prevent electrostatic or electromagnetic interference between the enclosed wires and external fields.

Cable Assemblies: Cable assemblies are collections of wires or cables banded into a single unit with connectors on at least one end

SCSI Cables: SCSI cables are used for high-speed bus connections between small computers and intelligent peripherals such as hard disks, printers, and optical disks.
