Converts general purpose electric current from the mains to direct current for the other components of the computer.
A fast storage area that is directly accessible by the CPU, and is used to store the currently executing program and immediately needed data.
Stores programs and data even when the power is off, but requires power to perform read and write functions during usage.
Data storage device using rapidly rotating discs coated with reflective material and read using a laser diode.
hard disk drive
Data storage device used for storing and retrieving digital information using rapidly rotating platters coated with magnetic material.
solid state drive
Data storage device using integrated circuit assemblies as memory to store data persistently.
Processes graphics output from the motherboard and transmits it to the display.
Internal computer expansion card that facilitates economical input and output of sound signals to and from a computer.
A computer hardware component that connects a computer to a computer network.

The basic unit of information in computing and digital communications which can have only one of two values, most commonly represented as either a 0 or 1.
A unit of digital information in computing and telecommunications that consists of eight bits, permitting the values 0 through 255 and used to encode a single character of text.
A device inside or attached to a computer case used for active cooling.
A computer bus that transfers data on both the rising and falling edges of the clock signal.
A class of memory integrated circuits used in computers that makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals.

A unit of frequency defined as 10^6 (1 million) cycles per second.
A term that refers either to a company that makes a part or subsystem used in another company's end product or collectively to all of the various manufacturers involved in the final assembly of an end product.
A personal computer running Microsoft Windows, used in contrast with Mac.
A local computer bus for attaching hardware devices in a computer, which replaced the original ISA and VESA bus configuration.
A high-speed serial computer expansion bus standard designed to replace the older PCI, PCI-X, and AGP bus standards.
A computer bus and expansion card standard that enhances the 32-bit PCI Local Bus for higher bandwidth.
