| A | B |
|---|
| Application Software | type of software that includes programs that help people do certain tasks |
| Binary Code | language a computer can understand. Binary code is made up of a series of ones and zeros. |
| Byte | a single character of data. A Gig, or gigabyte (GB) equals 1,000,000,000 bytes of data. |
| Central Processing Unit | a silicon chip that processes data and carries out instructions given to the computer. The central processing unit is also known as the microprocessor. |
| Compact Disc | is an optical storage device that uses laser technology to store information. It is read by a CD-ROM drive in a computer and can hold the equivalent of 500 floppy disks. |
| Computer | a device that can store, retrieve, manipulate and process data to produce an outcome. |
| Floppy Disk | A floppy disk is a magnetic, non-rigid storage device that can be used to store data and transport it to another computer. It is encased in a plastic sleeve to protect its data. |
| Hard Drive | storage device that reads and writes data to and from a round, rigid disks in the computer. |
| Hardware | the physical equipment of a computer. Hardware includes input devices, the central processing unit, output devices, and memory. The main parts are the central processing unit (CPU), the monitor, the keyboard, and the mouse. |
| Input Device | a device through which a computer takes in information. Input devices include keyboards, mouse devices, and scanners. |
| Keyboard | input device that is used to type text and commands into a computer. |
| Monitor | output device that displays text, objects, graphics, photographs, video, and animation on a screen. |
| Mouse | A mouse is a hand-held input device that controls the cursor |
| Network | two or more computers linked together to share files, software, and resources, such as printers. |
| Operating System | the most important type of system software that manages how a computer's hardware and the central processing unit communicate, manages files, and runs application software. |
| Output Device | a device through which a computer sends out information. Output devices include monitors, printers, and speakers and headphones. |
| Peripherals | Additional components besides the main parts of the computer such as printers and scanners. |
| Printer | output device that transfers information to a hard copy, such as paper or a transparency |
| Random Access Memory | Random access memory, or RAM, is a number of silicon chips inside a computer that hold information that is being used by the central processing unit as long as the computer is turned on. Also known as short-term memory, it forgets everything it knows when the computer is turned off. |
| Read Only Memory | Read only memory, or ROM, is the small bit of memory that stays in the computer when it is turned off. It is ROM that lets the computer “boot up” or get started. ROM holds the instructions that tell the computer how to begin to load its operating system. |
| Program | application or software. can be done by a computer. |
| Processing | basic computer function that refers to when a computer uses information. |
| Scanner | input device that is used to change images into information that a computer can read. |
| Software | a set of instructions that makes computer hardware work. Software is also known as programs or applications. |
| Storage | basic computer function that refers to when information is saved in a computer.. |
