Types of networking

                        In networking we can divide network into two types. Each type has their own advantages and disadvantages. The two types of network is

• ·         Peer to peer
• ·         Client-server

Peer to peer network

                        Peer to peer is a network that connects two or more computers to sharing purposes. In peer to peer network we can say all PC’s are in equal. That means there are no server PC’s (main PC’s). and also at a time a PC can be a server and that PC can share resources to another PC and that PC can be a client also and it can receive resources from another PC as well. Following is a diagram of peer to peer network. 

Advantages of peer-to-peer network

1. ·         All PC’s are equal
2. ·         Resource can share by any node
3. ·         No special permissions needed
4. ·         Easy to share

Client-Server network

                        Client-server network is a network which has a centralized device as Server. In this network the centralized device is only the server and other PC’s cannot be a server. The server device can share resources and other PC’s can get them.in this network all PC’s are connected to the server. Following is a diagram of client-server network.

Advantages of client-server network

1. ·         Clear management  (files are saved in a central place)
2. ·         Protection from virus
3. ·         Protection from cyber crimes.
