  1. 2. Dynamically addresses devices allocated by these servers and can change regularly.
  2. 7. Wide Area Network, Computers generally linked over a wide area, Business will not own the medium used to connect the machines e.g. telephone system , Files are not very secure
  3. 9. A set of rules that govern the transmission of data
  4. 10. Any type of local area network (LAN) in which the nodes (computers or computing devices, often portable devices) are not connected by wires but use radio waves to transmit data between them.
  5. 13. For a transmission medium, the range of signal frequencies it may transmit. (Hz)
  6. 14. 32 bits, written as dotted decimal addresses.E.g. 192.168.27.234
  7. 15. Trademarked IEEE 802.11 technologies that support wireless networking of home and business networks.
  8. 18. A system in which some computers (the clients), request services provided by other computers, the servers.
  9. 20. A device that receives packets or from one host (computer) or router and uses the destination IP address that they contain to pass them correctly formatted, to another host (computer) or router.
  10. 21. contains a database of IP addresses and domain name mappings.
  11. 22. The full address used to find files on the Internet.
  12. 23. Local Area Network, Computers generally linked over a small area, Business will have control over the medium used to connect the machines , LAN's are secure ,LAN's can share hardware as well as software & data

  1. 1. the complete domain name for a computer on the internet.
  2. 3. IP range that has to be regetered with Internet Registries.
  3. 4. e.g. 10.0.0.0 – 10.255.255.255 or 172.16.0.0 – 172.31.255.255 or 192.168.0.0 – 192.168.255.255
  4. 5. a global interconnection of computers and networks.
  5. 6. introduced to split large networks into smaller networks.
  6. 8. a service provided on the Internet.
  7. 9. A network that has no dedicated servers. All computers are of equal status and can both share resources themselves and use resources from other computers, ie they are peers.
  8. 11. (Internet Corporation for Assigned Names and Numbers) oversees the allocation of domain names and addresses.
  9. 12. A computer that provides shared resources to network users.
  10. 14. 128 bit address introduced to solve the problem of diminishing address space.
  11. 16. The number of bits transmitted per second (bps)
  12. 17. The rate at which signals on a wire may change.
  13. 19. IP range that cannot be found on the internet
