Across
  1. 1. takes data received from the user and creates a response, or output, for the user.
  2. 4. high-performance computer that provides centralized storage, processing, and overall management of large amounts of data
  3. 5. device that uses software to convert an image to text that can be used by the computer.
  4. 6. part of the computer that stores information for immediate processing
  5. 9. name of the device; also called the volume name.
  6. 12. combination of circuitry and software that holds instructions for initializing hardware.
  7. 13. (SSD) storage device that operates similarly to RAM, but they have and integrated circuit to store data as involatile memory rather than volatile memory.
  8. 14. sealed unit that contains a stack of individual disks, or platters, which are magnetic media that rotate at a very high speed; also called a hard drive.
  9. 16. pen-like device that functions as a writing utensil but uses digital signals to draw instead of graphite or ink.
  10. 18. location where data is kept by the computer so it can be viewed, played, or otherwise used
  11. 20. speed rating of a CPU
  12. 21. special type of computer that stores data and responds when requested by other computers on a network
  13. 23. data provided to the user.
  14. 24. data that is entered, scanned, or otherwise sent from the user to the computer system
  15. 25. device that senses applied pressure and sends signals to the CPU
  16. 28. random-access memory; memory that can be changed
  17. 31. converts sound into data that can be used by the computer
  18. 32. circuitry that fetches each instruction from the list directed by the program being run.
  19. 36. device with one or more buttons that can be moved on a flat surface to control the cursor.
  20. 39. processing device designed to meet the needs of an individual user, whether in the home, a business, or a school.
  21. 41. input device that allows the user to control the movement of the cursor, or pointer, on the screen.
  22. 42. device with multiple metal fins that is designed to draw heat away from a CPU.
  23. 43. optical-character recognition; type of software that can be used with image scanners to digitize text so the computer understands it as text characters.
  24. 45. method of storing data on remote servers through an Internet connection.
  25. 48. read-only memory; memory that cannot be changed
  26. 49. digital device that uses electronics to create electrical signals to represent data.
  27. 50. entire collection of a basic computer and the attached devices
  28. 51. converts data into sound
Down
  1. 2. (CPU) device that fetches coded instructions, decodes them, and then executes (runs) them.
  2. 3. made of iron oxide-coated disks that can be selectively magnetized to store on-off signals (1s and 0s).
  3. 7. attached devices that are not critical to computer operation; also called a peripheral.
  4. 8. physical components of the computer
  5. 10. (OS) software that manages all the hardware devices, as well as locating and providing instructions to the CPU
  6. 11. (ALU) digital circuit that temporarily hold in-process data and manages all arithmetic operations such as addition and subtraction.
