Peer-to-Peer Network (P2P)

A network in which devices share resources directly with each other without a dedicated central server.

Definition

Peer-to-peer networks are simple and inexpensive for small groups but scale poorly and have decentralized security. Some applications, such as BitTorrent, use P2P architectures across the Internet.

Example

Two home computers share a printer and folders without a server.

Exam tip

P2P suits small, low-security environments; client-server suits enterprises.
