  1. The main types of computer network:
  2. O personal area network (Pan)
  3. O Local area network (LAN)
  4. O Wide area network (WAN)
  5. Personal area network (PAN)
  6. A pan is a very small network that usually consist of personal devicezs that interconnect including:
  7. Computers, tablets, phones, Bluetooth headsets, printers.
  8.  
  9. Bluetooth PAN
  10. A Bluetooth pan is where Bluetooth enabled devices would connect together to form network. An example of this would be a phone and a hands-free headset connecting together in which voice is transferred between the two devices.
  11.  
  12. Local area network (LAN)
  13. A local area network (LAN) is a group of compuiters and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment. Computers and other mobile devices use a lan connection to share resources such as a printer or network storage.
  14. Advantages
  15. -Speed – One of the major advantages with LANs are the speeds they can reach. A LAN can operate up to 30x faster than a WAN
  16. Cost
  17.  
  18. Another advantage to aving a LAN connection is the cost. It is relatively cheap to have as it tends to require less hassle to set up and less advanced infrastructure to keep it running.
  19. Ease of setup
  20. A LAN connection tends to require some relatively simple things to set it up. All you need is some Ethernet cable or a WI-FI signal. Simply put, you cannot buy an Ethernet cable that will reach throughout an entire building, and a wi-fi connection rapidly deteriorates as you get further than a few dozen meters away.
  21.  
  22. Wise area network (WAN)
  23. A wide area network is a computer network that extends over a large geographical distance. A wAN connects different smaller networks, including local area networks (LAN). This ensure that computers and users in the location can communicate with computers and users in other locations. The internet Is a big example of WAN.
  24. Advantages:
  25. Allowing for much larger and more intricate network – Can cover near infinite geographical distance
  26. Sharing of data
  27. Disadvantages:
  28. Speed is slower compared to lan due to size – the further the distance the slower the network.
  29. Harder to set up High cost – Technology required for wan is expensive.
