Computer Networking & Repair Terms & Definitions

Processor

This is the hardware within a computer that executes programs.

Microprocessor

A microprocessor is a central processing unit, or CPU, contained on a single integrated circuit.

Storage System

A storage system consists of computer components used to retain digital data.

Power Supply

The power supply converts main AC current to low-voltage regulated DC current used to power an electronic device.

Expansion Card

An expansion card is a circuit board that can be added to the motherboard to give extra memory for processing data.

RAMl

Random Access Memory, or RAM, is the term given to computer data storage used to store frequently accessed data to increase the speed of the system.

Firmware

Firmware is permanent software programmed into a read-only memory that controls, monitors, and manipulates the data stored in an electronic device.

Peripherals

Peripherals are devices used to input or output data to and from the user and an electronic device. The most widely used peripheral devices include mice, keyboards, monitors, and printers. I/O Operation Terms & Definitions I/O stands for input/output. This term refers to the communication between an electronic device and a person, the internet, or another information processing system.

VGA

Video Graphics Array, or VGA, is the connector typically used to plug a peripheral, most likely a monitor, to an electronic device.

S-Video

A standard definition video connection, or S-Video, separates black-and-white and color signals from the computer to a monitor.

DVI

Digital Visual Interface, or DVI, is used to transmit digital signals from peripherals to a computer.

HDMI

High-Definition Multimedia Interface, or HDMI, is used to transmit data between components, typically an electronic device and monitor or television.

Motherboard

A motherboard is a printed circuit board containing the components of an electronic device.

Logic Counters

Logic counters are a number of latches with two stable states that are connected in sequence or in a series. Hardware Component Terms & Definitions Hardware components are the physical parts of a computer. Hardware is directed by the software to execute commands.

Memory

Memory is a temporary storage area that holds data and instructions for an electronic device to function.

Shift Registers

Shift registers are used for the storage or transfer of data using the binary number system.

Logic Gatesl

Most logic gates have two inputs and one output. Every terminal is in one of the two binary conditions, 0 or 1.

Binary Number Systems

This is a base 2 numerical system which uses two different symbols to represent number values. The two different symbols are 0 and 1.

Hard Soldering

Hard soldering is the connection of two pieces of metal at a high temperature. Digital and Binary Electronics Terms & Definitions Digital and binary electronics are digital electronics that handle digital signals with discrete bands of analog levels.

Soft Soldering

Soft soldering is the joining of small intricate parts that have low melting points.

TCP/IP

Transmission Control Protocol/Internet Protocol, or TCP/IP, is a set of networking protocols allowing multiple computers to communicate.

SOHOl

Small office/home office, or SOHO, is sometimes called a virtual office. The term SOHO describes the network of a small office or home office.

Wi-Fi

Wireless fidelity, or Wi-Fi, is wireless local area networking for computers or devices that connect to the internet via a wireless access point (WLAN).

WANS

Wide area networks, or WANs, are computers that are too far apart for a local area network and are therefore connected by telephone or radio waves.

LANs

Local area networks, or LANs, are computers that are close enough to connect usually in the same building.o
