P2P networks are the next evolutionary step in the development of the Internet. At least, proclaim it, the developers of P2P software. File sharing is to share files (music, videos, software, photos, etc.) between different users simultaneously connected to the Internet. Peer to Peer with no server-client relationship, P2P is an exchange of equal, meaning that different machines have both the server role and user. Plus the download is popular, there are more Internet users who download and then redistribute that much so it is easy to download.
The WWW (HTTP protocol) is often referred to as one-way street, because regardless of interactivity, in essence, data in one direction are transported to the user. P2P lifts restriction on them and allows direct data traffic between user groups. Sites, download files, databases, Internet itself must not be stored on Web servers in the. The users access the files directly from the PC. Somehow it is when P2P networks are closed, the other is different types available to the public, and it only requires a registration. Within the P2P networks can be as many sub-groups with limited user communities to realize again.
There are several networks of peer-to-Peer: BitTorrent Gnutella, Gnutella2, eDonkey2000, DirectConnect, DC + +, Mute, etc.. Each network has its differences and has its own features. Example, if a file is transferred via Gnutella will not necessarily available on eDonkey. To share your file, you must download a software like BitTorrent or Emule available on many download sites. The software lets you share a folder on your hard drive, so be careful what you put into this folder to avoid the dissemination of files, photos or videos that were not meant to be shared. If instead you are looking for a particular file, search engines integrated with P2P software are available.
P2P is a solution for file sharing but it also has many disadvantages. The reliability of files you can download to be taken him on the other computers are not insured, so you can download a virus, Trojan or a file that was not the one desired. Solutions easier and safer than Peer to Peer exist. NextSend is one solution, safely and for free you can share photos, videos and other files.
If all the nodes (peers) in a network communicate with each other on the same level, also referred to as peer-to-peer (P2P). Each node can take advantage of services and at the same time they also provide the traditional client-server topology is broken. With respect to resources such as bandwidth and processing power of the P2P approach opens new possibilities that are not restricted by far the sharing of music and movie files.
