Unit 1: Hardware and Software
1. Application software – computer software created to allow the user to perform specific a job or task. Examples: Word processing, Spreadsheets, Database, and Graphics software.
2. Central Processing Unit (CPU) – executes commands from a computer's hardware and software; the principal computer chip that contains several
processing components, which determines the computer's operating speed; the "brain" of a computer.
3. File management – A program on a computer that allows the user to create, edit, view, print, rename, copy, or delete files, folders, or an entire file
system.
4. File type – an extension at the end of a file name, indicating which application was used to create a document; i.e., Word files end in .doc and Excel files end in .xls.
5. Input device – data entered into the computer through a variety of devices such as a keyboard, microphone, scanner, flash drive, or mouse.
6. Logon – the action of gaining access to a computer or a network by entering a username and password; also called Login/Sign In.
7. Memory - computer chips that store data and programs while the computer is working; often called RAM or Random Access Memory.
8. Operating system - system software that acts as a "go-between", allowing computer hardware and other software to communicate with each other.
9. Output device – allows the user to view or listen to the data a computer processes such as a monitor, printer, headphones, or speakers.
10. Peripheral – additional hardware that isn't necessary for a computer to function, but does enhance how the computer can be used; Examples: Scanner, Webcam, Computer joystick.
11. Save – storing data for later use
12. Save As – a feature that allows the user to change the attributes of a file (such as location, file name, or file type) before saving it
13. Storage device – external hardware used to store and retrieve data, such as a disk drive, CD/DVD drive, flash drive, or tape drive
14. System unit – a computer case that contains the CPU, power supply, memory, and storage; Examples: BIOS, Microsoft Windows, Mac OS X, Linux, or utility software
15. System software – software responsible for the general operation of a computer system, including the operation of hardware, running application software, and file management
