  Types of network
  
  Geographical area:
  PANs (Personal Area Networks) typically
  include a laptop, a mobile phone and a
  PDA;
  LANs (Local Area Networks) cover a building;
  MANs (Metropolitan Area Networks) cover a campus or a city;
  WANs (Wide Area Networks) cover a country or a continent.

  Topology:
  In a bus network, all the computers are connected to a main cable, or bus.
  In a star network, all data flows through a central
  hub, a common connection point for the devices
  in the network.
  In a ring network, all devices are
  connected to one another in a continuous loop, or
  ring.

  What is wireless networking?
  
  Wired networks are linked by Ethernet cables, phone lines and high-speed fibre optic cables. Wireless networks, however, use electromagnetic waves, such as
  radio waves, to transmit data. These are the main types of wireless networks:
  Satellites – for long distances
  WiMAX – for connecting Wi-Fi hotspots
  Wi-Fi – for medium-range distances
  Bluetooth – for short distances
  GSM – for mobile phones
  
  What do I need to set up a home wireless LAN?
  
  You’ll need computers equipped with a wireless adapter or wireless card, a wireless access point (a wireless router) and a broadband internet connection.
  
  Which is better, a wired or wireless LAN?
  
  Wired LANs are more difficult to install, but they are cheaper, faster and more reliable. Wireless networks let you move, or roam, from one access point to another, but they are less secure and subject to interference.

  In a basic network, two computers are connected by cable to allow file sharing.
  WANs cover a large geographic area, like a country or even multiple countries. They are built by large telecommunication companies. The largest WAN in existence is the Internet.
  In many homes, Ethernet cables are used to connect
  computers. Phone or cable TV lines then connect the
  home LAN to the ISP. Much of the Internet uses high-speed fibre optic cable to send data over long distances.
  Wi-Fi is the standard technology for building wireless LANS and public hotspots. Bluetooth networks allow handhelds, mobile phones and other devices to communicate over short distances. Cellular networks are used in mobile phone communications.
