The full form of P2P is ” Peer to Peer .” In a P2P network, “peers” are computer systems that are connected to each other via the Internet. Files can be shared directly between systems on the network, without the need for a central server. In other language, then, each computer is built on a P2P network with a file server as well as a client.
To join a peer-to-peer network with a computer, only two things are required, an Internet connection and a P2P software. Common P2P software programs include Kazaa, Limewire, BearShare, Morpheus, and Acquisition. These programs connect to a P2P network, such as “Gnutella,” which allows thousands of systems to access the computer with that network.
Once connected with the network, P2P software allows you to search files in other people’s computers. At the same time, other users can also search your computer’s files on the network, but typically in a single folder that you designed to share.
By the way, P2P networking makes file sharing easy and convenient as well, while it increases the chances of much more software piracy and illegal music downloads. At the same time it is best that you download software and music only from legitimate websites.
