Networks

1. A file server is a computer on a network that holds files that can be used by other computers on the same network.

2. A client sever network has one computer acting as a file server

3. In a peer-to –peer network all computers are of equal importance.

4. Bus network topology

   • Advantages
     • Cheap network to setup
     • If a computer fails the network continues to work
   • Disadvantages
     • Speed of data is slow
     • If the network cable breaks(the main cable), none of the computers can access the network

5. Ring network topology

   • Advantages
     • Cheap network to setup
     • Data speed is continuous(no data collision)
   • Disadvantages
     • If any computers or the network cable breaks, it can affect the whole network

6. Star network topology

   • Advantages
     • All the computers are connected to a central hub which directs the flow of data.
     • Direct access to the file server means the access is fast.
     • Each computer has its own connection to the hub so, if one computer or cable breaks down, it does not affect the rest of the network all the other computers will still be able to access the file server.
   • Disadvantages
     • Expensive to install due to cabling needs
     • If the hub or file server at the centre of the network fails, all the computers are affected.

7. LAN-local area network

8. WAN-wide area network
