Computer hardware includes all of the computer components that are physical, touchable pieces of equipment.
The combination of input devices, central processing unit, memory, output devices, and storage devices.
Computer programs created to accomplish specific tasks or perform specific functions.
A set of computer instructions, written in a special computer language, that tells a computer how to accomplish a given task.
A small square of highly refined silicon on which miniaturized electronic circuits have been embedded.
ROM (read-only memory)
A chip created to hold a stored program such as the BIOS (Basic Input/Output System) that provides instructions to the computer as to how to start itself up.
The process of powering on a computer during which it reads the instructions stored in ROM to tell it how to start itself up.
operating system (OS)
A program that tells the computer how to function and how to manage its own operation.
The component of an operating system that establishes the methods of interaction (via menus, text, and/or graphics) between the user and the machine.
An operating system from Microsoft used by certain types of personal computers that tells the computer how to work.
GUI (graphical user interface)
The method of interaction in which the user enters commands or makes selections by using a device such as a mouse or trackball to point to and click on icons displayed by the monitor.
A set of instructions that tell a computer how to complete a unique task such as word processing, database management, or drawing.

CD-ROM (compact disc - read-only memory)
An optical media that stores digital data via tiny holes burned into the disc surface with a laser.
CD-RW (compact disc - rewritable)
A type of compact disc that allows the user to record many times and to change the data stored on the CD.
CD-R (compact disc - recordable)
A type of compact disc on which the user can record (write) data, but once recorded, the data cannot be changed.
DVD-ROM (digital versatile discs)
A laser disc that is similar to a CD-ROM but is designed to hold significantly more information than a CD.

local area networks (LANs)
Small networks that connect computers in local areas, such as a classroom or school.
wide area networks (WANs)
Networks that connect computers across a wide area, such as all of the schools in a district or all of the districts in a state.
Data that are broken into small units and sent through a network one unit at a time.
The carrying capacity of electronic transmission media for sending and receiving information, which translates to the speed at which the network can transmit data.
A combination of software and hardware that provides various levels of security measures designed to keep unauthorized users and computer hackers out of networks and to keep data private and safe.
