Peers in Peer to Peer computer network behaves like semi client & semi semi server. Every computer in network is allowed to share its resources like printer, scanner or other external devices connected.

Limitations of Peer to Peer Architecture :

1. No Centralized system which results administration problems.
2. Less secured
3. All links in networks are unreliable.

Peer-to-Peer networks are mostly useful in small organization where organization have less computers (about less than 8 or 10) & less security is required.
