  3. 6. / all the physical parts of the computer system
  4. 10. / a main computer that provides a storage area for data files on a network
  5. 14. / an electronic device used to convert signals from analogue into digital ones.
  6. 15. / a low-cost centrally- managed basic computer with a keyboard and display, but no disk drives or expansion sots
  7. 16. / ability to transfer data on both directions simultaneously
  8. 17. / a hardware device, often equipped with a keyboard and screen, through which data can be entered or displayed
  9. 19. / the part of a network communications process that ensures the message is transmitted in a language that the receiving computer can interpret
  10. 21. / an electronic device that isolates a network system from high voltage and allows it to use the mains electricity cables for connecting computers together and transferring data
  11. 22. / a type of signal that has only two levels- on and off
  12. 23. / programs and applications
  13. 24. / a main data communication s cable connecting LANs together
  14. 25. / a network computer that does some of the processing
  15. 27. / stop-start transmission, data is sent one byte at a time
  16. 35. / a data bit that marks the end of a data block in a network transmission
  17. 36. / the computer that uses the services
  18. 37. / an electronic device for connecting different types of networks together
Down
  1. 1. / the only part of a network communications process that a user sees etc.
  2. 2. / the most common way of connecting computers in LAN
  3. 4. / the part of a network communications process that opens communications and has the job of keeping the straight the communications among all nodes on the network. It sets boundaries for the beginning and end of the message and establishes the way data is sent.
  4. 7. / a network that covers a small area e.g. an office or a building
  5. 8. / a common type of network cable that uses two wires twisted together to reduce interference from external signals
  6. 9. / the part of a network communications process that
  7. 11. / the interconnection of computers using signals carried through the air instead of through the connecting cables
  8. 12. / calculated value that is stored with data to detect any errors that may occur when data is copied or transmitted
  9. 13. / an electronic device for connecting different types of networks together and determining the best path for the signals
  10. 18. / transmission where data is sent in blocks
  11. 20. / an electronic device for dividing a LAN into separate parts or connecting similar networks together
  12. 26. / a network computer that doesn’t have a processor, all the processing must be done by the server computer
  13. 28. / a type of Network where the main server provides the services and client computers are attached
  14. 29. / the part of a network communications process that forms the data into packets and selects a route for the message
  15. 30. / the part of a network communications process that protects the data being sent. It subdivides the message into segments and creates the checksum.
  16. 31. / a type of signal that can take any value from minimum to maximum
  17. 32. / a start or stop bit pattern that marks the beginning or end of a transmitted data block
  18. 33. / a data bit that marks the beginning of a data block in a network transmission
  19. 34. / an electronic device at the center of a star network topology, amplifies the signals
