Networking

1. Local area network (LAN)

   • A LAN is a network that connects computers in a limited area such as school work or your own home.
   • There are two types of LAN:
     • Peer to peer network - This is where two or more computers are directly connected, allowing data and applications to be shared
     • Client/Server- This is where all computers in a network are connected to a main server
       • Advantages:
       • Disavantages: if the server breaks the computers won't work

2. Ring network

   • A ring network is where all computers in a network are connected in a circle.

3. Bus network

   • A bus typology is a type of network where each computer is connected by a single cable

4. Network policies

   • Archiving
     • This is where you store old but needed data way from the main server to somewhere else. This saves space on your network.
   • Back up
     • This is where you make a copy of all of your data and store it in a remote location.
   • Acceptable use policy
     • A set of rules that states what is expected of people using the network.
   • Failover
     • Automatic switching to a backup computer system in the event of a system failure. For example a car battery.
   • Disaster recovery
     • A set of strategies in case of disaster (power cuts, natural disasters or hacking) to make sure that you do not lose your work. for example backing up your work in a remote location.
