Across
  1. 6. The amount of data that can be sent and received successfully in a given time
  2. 7. None of the data is lost, it is encoded differently
  3. 9. Store the mathematics to draw coloured shapes
  4. 10. a data container that saves the data values during Java program execution.
  5. 11. Medium storage capacity with very quick access to data
  6. 14. Wired connection have a higher bandwidth than wireless connections
  7. 16. stores text, such as "Hello". String values are surrounded by double quotes
  8. 18. Some of the data is lost and can’t be recovered.
  9. 19. The delay from transmitting data to receiving it.
  10. 20. A block of memory for storing data which is likely used again
  11. 23. Random access memory
  12. 24. stores integers (whole numbers), without decimals, such as 123 or -123
  13. 26. read-only memory
  14. 28. Too many users or devices on the same network can cause the network to slow down if there is insufficient bandwidth for data
  15. 31. Used to maintain the computer system
  16. 32. Pictures constructed from coloured squares called pixels.
  17. 36. are ignored by java (will not be executed)
  18. 37. Text Based
  19. 38. A general term covering all computer programs. Most software falls into broad categories such as application, system, and utility software
  20. 39. Low capacity storage with slow access to data
  21. 40. Computers designed for a specific task, ex, heart monitors
Down
  1. 1. All physical parts of a computer system and its related devices, both internal or external. Ex: motherboard, hard drives, RAM, monitors, keyboards,etc
  2. 2. A server controls accessed security to one shared file store.
  3. 3. Piece of application software
  4. 4. Provides a platform on which users can run programs
  5. 5. Is needed when there is not enough physical RAM to store the open programs
  6. 8. Responds to questions in a spoken language
  7. 12. stores single characters, such as 'a' or 'B'. Char values are surrounded by single quotes
  8. 13. Stored in 24 bit colour depth (2^24 = over 16 million colours)
  9. 15. Windows Icon, menus, pointers (WIMP)
  10. 17. Is needed because ROM is read only and RAM is volatile.
  11. 21. Less reliable connections increase the number of errors that occur when data is transferred
  12. 22. Reducing the number of bits in a file
  13. 25. The component of the computer that holds data and programs that are currently in use.
  14. 27. Additional data stored with the image to define width, height, colour depth and colour palette
  15. 29. stores floating-point numbers, with decimals, such as 19.99 or -19.99
  16. 30. The concerns are those where the manufacturing and use of computers has had a negative impact on the environment
  17. 33. A computer on a network, and is equal to all others
  18. 34. High storage capacity with quick access to data
  19. 35. stores values with two states: true or false
