Network Model Types With Explanation

Network Model Types With Explanation

There Are Three types of computer networks.These are as follows:

• Client-Server Model
• Peer-To-Peer Model
• Hybrid Model

Client-Server Model/Dedicated Server Network:

In client-Server model,one or more computers works servers and other computers work as clients.The server Computer controls the whole network.It is used to store data and programs to be shared among different computers in the network.It may also share a printer attached with it.Server is more powerful computer than other computers in the network.It perform most of the processing in this network model.

The client computer requests a service from the server computer.The server computer provides the requested service to the client computer.Some server are called dedicated servers.A dedicated server is used to perform  a specific task.A Print Server is used to manage printers and printing task.Similarly,Network Server manages network resources.

Advantages:

Some important advantages of client-server model are given as:

• It minimize and low the volume of data traffic on the network.
• It also give the service of faster responses to the clients.
• It require less powerful computers as clients server model

Disadvantages:

• It is more expensive model of network because of server computers are often costly.
• The operations perform by the server computer id stop all over the network when server goes down.

Peer-To-Peer Model:

All computers in peer-to-peer model have same status.There is no server computer to control other computers.Each computer in this network can have access  to devices and files on other computers.Each computer independently store its own software and information.

Advantages:

• It is easy to setup.
• It is easy to maintain.
• It does not require expensive server computer.

Disadvantages:

• Heavy use can slow down the network speed.
• It also gives less security of data in peer to peer network model because files are stored at different locations in the peer to peer network model.

Hybrid Model:

Hybrid model is a combination of client/server model and peer-to-peer model.Many networks use a mixture of both networks models.This model can provide the advantages of both models.
