Types of Networks

Types of Networks

1. Peer to Peer

   • Advantages of Peer to Peer
     • Cost Saving - no server required
     • No network manager needed - all responsible for your own machine
     • Easy to set up - simple network
     • Low operating costs - less set up and maintenance
     • Peer responsibility - users decide what programmes others can use on the network
   • Disadvantages of Peer to Peer
     • No central back up store
     • Users need more IT knowledge - responsible for your own files on your own PC
     • Poor Security
     • Computers may run slow if all users access the same resource
     • User may experience difficulty finding files if not organised correctly
     • Only suitable for networks (15 PCs or less)

2. Client

   • Disadvantages of Client
     • Much more expensive than a P2P network
     • If server breaks down the whole network goes down - meaning all clients connected to the server will not be able to carry out any tasks
     • Needs a network manager to manage the network - this means hiring a specialist knowledge staff member (added cost)
     • Complex and sophisticated software is required in order to run the network - This software can be expensive
   • Advantages of Client
     • Security is better as it is controlled centrally by a dedicated staff member
     • Centralised data - data held on the main file sever, everyone can access same files
     • Backups made by central server at regular intervals meaning data is less likely to be lost
     • Faster access to programmes due to fast main server computer controlling the network
     • Centralised admin - all admin work performed centrally so you do not have to worry about carrying out any admin tasks
