A nonvolatile, electronic space on a magnetic or optical disc that the computer can use to store instructions and data for use at a later time.
A processing cycle that includes the steps of taking data in, processing them, storing them as necessary, and outputting the finished information to the user.
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.
Specialized programs that manage, improve, or oversee computer operations.
integrated software package
A collection of the main features of popular applications integrated into a single comprehensive application.
A computer peripheral that the user can use to enter data into a computer.
The pieces of hardware that move information (data that have been processed or accessed) out of the computer.
Data that are still in an electronic form within the computer.
The printed version of material generated by a computer.
The clarity and crispness of the image on the monitor screen or printer output.
The smallest unit of information in an image.
LCD (liquid crystal display)
A display screen made of two sheets of a flexible polarizing material with a layer of liquid crystal solution between the two.
dpi (dots per inch)
A measure of resolution in printers and some other output devices.
CPU (central processing unit)
The "brain" of a computer, incorporated into a single microprocessor chip.
RAM (random-access memory)
The chips that make up a computer's temporary memory area.
hard disk (drive)
A disk or platter(s) on which data, operating systems, applications programs, and most personal files are stored.
Approximately one billion bytes of data or characters of data.
Eight bits (on-off pulses) of data, roughly equal to one alphabetic (A) or numeric (1) character of information.
To create a duplicate copy on another storage medium for use in case the original copy is lost.
A nonvolatile, portable magnetic storage device.
USB flash (jump) drives
Using 1.1 or 2.0 interface, they use flash memory (no moving parts) to store data. Faster, smaller, and hold more data than floppy drives.
A collection of related data, usually a product of a single task that is saved on a storage device.
A digital organizer that is created by the user to hold related files on a disk; may also be known as a directory in non-Windows operating systems.
A program written specifically to disrupt computers and/or destroy data. They can copy themselves and infect computers.
Programs that detect and disable or destroy computer viruses.
Multiple types of media that are combined into an integrated whole that presents instructional content.
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.
A collection of computers and peripherals that are connected together so that they can communicate information and share resources.
An intelligent terminal or personal computer that is connected to a computer network.
A piece of equipment that offers a series of centralized connections to enable multiple computers to connect to a network.
Any workstation or peripheral that is connected to a network.
A powerful computer that provides services and enables sharing resources for computers on a network, such as email, program sharing, data storage and access, and printer sharing.
A network in which information is transmitted wirelessly via infrared, radio wave, or microwave technology rather than through wires that are directly connected to computers.
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.
Purchased rights to use a single copy of a software application for multiple computers/users as defined by the license.
