Network Architecture

The networking architecture or network model specifies how computers on the network interact and communicate with each other. The network of the personal computers may use Client-server Network or Peer-to-Peer Network.

Client Server Network

In it, computers are connected to a central device (server) and communication is done through it. The server is the main computer which provides services to the workstation. The server computer provides resources to the workstations when the request is made. An unauthorized person cannot access the resources of the server. There are different types of server like print server, file server and network server, etc.

Advantages of Client-Server Network Model

  • Only an authorized person can access the resources of the network.
  • It is more secure than the peer-to-peer network.
  • All the workstations can be managed from a single server computer.
  • The required application can be installed on the server computer instead on the individual workstation.

Disadvantages of Client-Server Network

  • All the workstation has to depend upon server computer.
  • It is difficult to set up the client-server network.
  • A trained administrator is required to handle it.

Peer to Peer Network

It is sometimes called workgroups. In this network, all the computers have equal responsibilities. Each computer has access to at least some of the resources on all the computer. Each computer in this network has equal right. It is suitable for the only small geographical area such as small rooms, building, school, etc.

Advantages of Peer-to-Peer Network

  • It is easy to set up a peer-to-peer network than a client-server network.
  • Each computer in the network has equal right and can determine resources to be shared.

Disadvantages of Peer-to-Peer Network

  • It has low-level security than the client-server network.
  • The expansion of the network is limited.
  • The network performances degrade with a heavy load.
Things to remember
  • The networking architecture or network model specifies how computers on the network interact and communicate with each other
  • The network of the personal computers may use Client-server Network or Peer-to-Peer Network.
  • In client-server network, the server is the main computer which gives services to the workstation.
  • Peer to peer network is known as work groups where all computers have equal responsibilities.
  • It includes every relationship which established among the people.
  • There can be more than one community in a society. Community smaller than society.
  • It is a network of social relationships which cannot see or touched.
  • common interests and common objectives are not necessary for society.

Questions and Answers
The differences between client-server network model and peer-to peer network model are as follows:

Client-server Network Model Peer-to-peer Network Model
It is a network model where there is at least one server and one or more workstations. It is a network model where there are two or more client and no server.
In this model, all the rights are with only server computer. In this model, all the computers have equal right.
It is known as domain model. It is known as workgroup model.

Any four advantages of client server network are as follows:

  • Only an authorized person can access the resources of the network.
  • It is more secured than the peer-to-peer network.
  • All the workstations can be managed from a single server computer.
  • The required application can be installed on the server computer instead on the individual workstation.

A network in which all the computers have equal right and are suitable foronly small geographical area such as small rooms, building, school, etc. is known as peer to peer network.

Some of the disadvantages of peer to peer network are as follows:

  • It has low level security than the client-server network.
  • The expansion of the network is limited.
  • The network performances degrade with heavy load.

A network in which all computers are connectedto a central device (server) and communication is done through server is known as client server network.

Some of the disadvantages of client server network are as follows:

  • All the workstation has to depend upon server computer.
  • It is difficult to set up the client-server network.
  • A trained administrator is required to handle it.

Any two advantages of peer to peer network are as follows:

  • It is easy to set up a peer-to-peer network than a client-server network.
  • Each computer in the network has equal right and can determine resources to be shared.
