Peer-to-peer networking provides a simple, low-cost method for connecting personal computers in situations where you want to share files and other resources such as a printer. Peer-to-peer networking does not require a server, meaning the added expense of a powerful computer to act as a server and a network operating system for the server is avoided in this approach to creating small networks.

   A peer computer basically acts as both a client and a server computer. Peer computers can access resources on the network, and they can supply resources to other peer computers.

   The only requirements for building a peer-to-peer network include installing an operating system on the PCs that supports peer-to-peer networking and then physically connecting the PCs.
