   • LANs and WANs
     • A LAN (local area network) is a network of computers within the same building, such as a school, home or business. A LAN is not necessarily connected to the internet.
     • A WAN (wide area network) is created when LANs are connected. This requires media such as broadband cables, and can connect up organisations based in different geographical places. The internet is a WAN.

2. Data packets

   • The main purpose of networking is to share data between computers. A file has to be broken up into small chunks of data known as data packets in order to be transmitted over a network. The data is then re-built once it reaches the destination computer. Networking hardware is required to connect computers and manage how data packets are communicated. Protocols are used to control how data is transmitted across networks.

3. Advantages

   • Upload files, share and connect with others online, communication, roaming profile

4. Dis-advantages

   • Reliance on network resources, expensive risk of viruses and hacking, specialist staff required
