Computer Network Architectures

Client Server Architecture:

In this type of architecture, there is one or more server and others are clients. Client computer is active with direct interaction of user. It request and receive services to or from the server. Server responses after receiving request of computer.

The network consisting of web-server is client-server architecture. The web server is created using network operating systems like Windows Server 2012 and web server application like Apache.

The advantage of this architecture is that data is located at the center to which security can be maintained easily through manageable routers or firewall. Another advantage is easiness to update data in server.

Disadvantage of this type of network is, there is only one failure point. That is, if the server is crashed, then the data is lost.

Moreover, there may be high load of request to server.

Peer-to-Peer Architecture:

In this type of network, there is no particular server. Every computer can act simultaneously as server and client. There may not be any restriction for any information access. In fact, computer simply connected in network is in peer-to-peer network. This type of network is easy to establish.
