Network Mind Map

Network Mind Map

1. Advantages

   • Hardware can be shared
   • Software can be shared
   • Data can be shared
   • Networked computers can communicate
   • The usage of computers on a network can be controlled by the network manager

2. Disadvantages

   • The cost of cabling and setting up is high
   • A virus can spread through a network very quickly
   • Hackers may gain unauthorised access to files saved on a network server
   • Networks can fail to work properly

3. File Server

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

4. A client–server network

   • A client-server network has one computer acting as a file server

5. A peer-to-peer network

   • In a peer-to-peer network all computers are of equal importance

6. Bus network topology

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

7. Star network topology

   • Advantages
     • If a cable/computer breaks, all of the other computers will still be able to access the files server
     • Direct access to the file server means the access is fast
   • Disadvantages
     • Expensive to install because lots of cabling is needed
     • File server fails, all the computers are affected

8. Ring network topology

   • Disadvantages
     • If any computer or the network cable breaks, it can affect the whole network
   • Advantages
     • Cheapest network to set up
     • Data speed is fat and continuous
