Across
- 1. stores information for the computer to process & instructions for the computer to complete certain tasks
- 2. describes the constant flow of electricity to maintain stored values
- 4. represents a connection to another page & is usually displayed on a Web page as underlined, colored text.
- 7. collections of wires that carry information in the form of electrical signals
- 8. a collection of software that spans the internet and enables the interlinking of documents & resources
- 9. a vast, international network of computers; crosses geographic borders and links computers
- 10. stores data as electrical charges in a series of memory "cells" made up of non-volatile electronic circuitry
- 14. carries out programmatic steps to process data, located on the motherboard
- 15. document that stores information (a song, an image)
- 16. uses intuitive, visual elements to simplify the process of viewing files & executing programs
- 17. metal platter that stores bits as magnetized and nonmagnetized spots, rotates under a sensor, and can retain data without power.
- 18. the programs that execute on the computer, carrying out tasks like word processing & accessing the Web
Down
- 1. a circuit board inside computers that stores electrical components and helps them communicate
- 3. allows the computer to receive data & instructions from an external source, such as a keypad.
- 5. a collection of programs that stores how the CPU, memory, and I/O devices work together to execute programs (largest & most integral systems software on a computer)
- 6. the physical components of a computer (you can "kick it")
- 11. utilizes high-speed circuitry to provide high-speed access to data
- 12. collection of 8 bits, capable of representing 256 different values
- 13. communicates with the CPU using lower-speed circuitry
- 14. device that receives, stores, & processes information
