Hard Drive
A data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic material.
RAM
Random-Access Memory stores the code and data that are being actively accessed by the CPU
ROM
Read-Only Memory stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or "booting" or "booting up".
CMOS
This battery is the same as a watch battery or a battery for a remote to a car's central locking system. Most batteries are CR2032, which powers the memory for date and time in the BIOS chip.
Buses
A communication system that transfers data between components inside a computer, or between computers.
Power Supply
Converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer. Also capable of running from a built-in battery.
CPU
Performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer.
Chipset
Mediates communication between the CPU and the other components of the system, including main memory.
Motherboard
The main component of the computer. Rectangular board with integrated circuitry that connects the other parts of the computer.
Expansion Card
Printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus.
Mouse
Input devices allow the user to enter information into the system, or control its operation.
Monitor
Output devices display information in a human readable form.
USB
Universal Serial Bus is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.
Optical Drive
A disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs.
Cooled Heat Sink
A passive heat exchanger that cools a device by dissipating heat into the surrounding medium.
Fan
Inside, or attached to, a computer case used for active cooling.
Video Card
An expansion card which generates a feed of output images to a display.
Sound Card
An internal computer expansion card that facilitates economical input and output of audio signals to and from a computer under control of computer programs.
Ethernet
Computer networking technologies for local area networks (LANs) and wide area networks (WANs).
Keyboard
An input device which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches.
