Based on Management method

Based on Management method:

Network architecture: 

• Network technology means network layout that tells us how computers are arranged and how tasks are allocated to computers. 
• It is also two types depending on the network management method:

i. Client-server architecture

ii. peer to peer (P2P) architecture

1. Client-server architecture: 

• A network architecture in which each computer on a network is either client or server. 
• Each device of the client can send data requests to one or more connected servers. 
• In term the server can accept these requests ,process them and return the requested information to the client. Ex: www, Email

Advantage:

• It has a centralized system, from which data can be easily backed up.
• Security is better in this network.
• The entire system is maintained by the server computer.

Disadvantage:

• In case of server Failure the entire network will be failed.
• Server maintenance cost is high.
• It requires a dedicated network administrator to manage all the resources.

2. Peer to peer architecture:

• Peer to peer is a type of network in which all the computers are directly linked together with equal capabilities and responsibilities for sharing data.
• There is no special server in it.
• Each computer manages its own Security.Ex: www, Email

Advantage:

• It is a cheaper network as it has no server.
• If one computer stops working it will have no effect on the other computer.

Disadvantage:

• It has a security issue as the device is managed itself.
• We can not backup the data because there is no server in this network.
