The network model/architecture defines "how the computer communication works in these networks". There are 3 types of network architectures:

  1. Centralized network
  2. Client Server Network
  3. Peer to Peer Network

1.) Centralized Network:

In it, the main computer is called host computer. Here, the workstation has no processing capability, they are only used for input output operations. It is run with a powerful operating system called UNIX or Linux.

2.) 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 gives services to the workstation. There are different types of server like print server, file server and network server, etc.

3.) Peer to Peer Network:

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

Very Short Questions

The differences between server and workstation are as follows:

Server Workstation
A server is an application or device that performs service for connected clients as part of client server architecture. A workstation is a personal computer that is used for high end applications such as graphic design, video editing,
It is the place on the computer which controls and manages other computer. It is the place where the client works
Web servers, application servers etc... are the examples of servers. Video and audio workstation are the examples of workstation.

The differences between hub and switch are as follows:

HUB SWITCH
It transmits the data packets to all the nodes connected on the network. It does not transmit the data packets to all the nodes connected on the network.
It cannot reduce the amount of unnecessary network traffic. It reduces the amount of unnecessary network traffic and improves the network performance.

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.

In centralized network,the main computer is called host computer. Here, the workstation has no processing capability, they are only used for input output operations. It is run with a powerful operating system called UNIX or Linux.
