Across
- 2. unit circuitry that fetches instructions from the list; decodes and executes instructions and places in the ALU
- 6. system collection of devices attached to the basic computer computer
- 8. part of the computer that stores information for immediate processing (code for computer programs, data for the programs, etc); measured in bytes
- 9. data that is entered, scanned, or otherwise sent from the user to the computer
- 11. device provides the computer with data on which it can act (keyboard, mouse, scanner, sensors that monitor information)
- 13. logic unit (ALU) digital circuit that temporarily holds in-process data and manages all arithmetic operations like addition and subtraction; logic tasks; video gaming
- 15. point of interface between the motherboard and external devices
- 16. called a system board, connects all the hardware in the computer; electric connections for all data transfer
- 18. processing unit (CPU) device that fetches the coded instructions, decodes them, and executes (runs) them; also known as a microprocessor or chip
- 19. device devices that are not critical to the computer operation
Down
- 1. speed measurement of CPU speed (gigahertz)
- 3. data provided to the user
- 4. location where data is kept by the computer so it can be viewed, played, or otherwise used (memory, hard disk, flash drives, ext. storage)
- 5. sink device with multiple metal fins that is designed to draw heat away from the CPU
- 7. access memory (RAM) memory that can be changed, holds the instructions the processor can immediately use; volatile
- 10. transforming of input data and acting on that data
- 12. serial bus (USB) industry standard for communication between devices and the computer
- 14. physical components of the computer (input device, memroy, processor, output device)
- 17. only memory (ROM) memory that cannot be changed; contains the information a computer will always need to operate (holds all the information, even when the computer is turned off)
