Networks

Networks

1. WAN- wide area networks

   • A computer network in which the computers connected may be far apart, generally having a radius of more than 1 km

2. LAN- local area network

   • a computer network that links devices within a building or group of adjacent buildings, especially one with a radius of less than 1 km

3. Advantages

   • Sharing devices such as printers saves money

4. Topologies

   • Bus
     • Advantages
       • It works well when you have a small network.
       • Easiest network topology for connecting computers or peripherals in a linear fashion.
       • Requires less cable length than a star topology
     • Disadvantages
       • Difficult to identify the problems if the whole network goes down
       • It can be hard to troubleshoot individual device issues
       • Not great for large networks
       • Terminators are required for both ends of the main cable
       • Additional devices slow the network down
       • If a main cable is damaged, the network fails or splits into two
   • Ring
   • Star
