A network model in which all computers can functions as clients or servers as needed, and there's no centralized control over network resources.

ADVANTAGES

 Less start-up costs to setup the network architecture - no need for a server

Easy to install and configure for the computers in the network

When a peer fails, it will not affect other peers so the network is reliable

DISADVANTAGES

Decentralized - No central repository for files and applications.

Less security - Does not provide the security that is available on a client/server network

Networking which one or more computers act as a server and the other computers (clients) on the network request services from the server

ADVANTAGES

Centralized: resources and data security are controlled through the server.

Better management of files : all files are stored in the server.

DISADVANTAGES

Expense: requires initial investment in dedicated server

Maintenance: large network will require a staff to ensure efficient operation
