What is a peer-to-peer network?

• In a peer-to-peer network, all computers are equal: there is no hierarchy among computers and there is no dedicated server. As a rule, each computer functions both as a client and as a server; in other words, there is no separate computer responsible for the administration of the entire network. All users independently decide what can be made publicly available on their computer over the network and to whom. 

• Peer-to-peer networks are also called workgroups. A working group is a small team, so there are usually no more than 10 computers in peer-to-peer networks. 

• A peer-to-peer network is quite suitable where:

1) The number of users does not exceed several people;
2) Users are located compactly;
3) Data protection issues are not critical;
4) Data flows are small;
5) No significant expansion of the office and, consequently, the network is expected in the foreseeable future.
