Network Classification by their Component Role

There are two type of networks.

  1. Peer To Peer Network
  2. Client Server Network

Peer to Peer Network – 

In peer to peer network each computer is responsible for making its own resources available to other computers on the network. Each computer is responsible for setting up and maintaining its own security for these resources and each computer is responsible for accessing the required network resources from peer to peer relationships. Peer to peer network is useful for a small network containing less than 10 computers on a single LAN. Peer to peer networks do not have a central control system. There are no servers in peer networks.

Advantages & Disadvantages of Peer To Peer Network

Use less expensive computer hardware
Not very secure
Easy to administer
No central point of storage or file archiving
No NOS required
Additional load on computer because of resource sharing
More built in redundancy
Hard to maintain version control
Easy setup & low cost

Client Server Network –

In client-server network relationships, certain computers act as server and other act as clients. A server is simply a computer, that available the network resources and provides service to other computers when they request it. A client is the computer running a program that requests the service from a server. 

A client-server network is one n which all available network resources such as files, directories, applications and shared devices, are centrally managed and hosted and then are accessed by client. Client server network are defined by the presence of servers on a network that provide security and administration of the network.

Advantages And Disadvantages of Client-Server Network

Very secure
Requires professional administration
Better performance
More hardware intensive
Centralized backup
More software intensive
Very reliable
Expensive dedicated software
