File sharing is the practice of making files available for other users to download over the Internet and smaller networks.
Usually file sharing follows the peer-to-peer (P2P) model, where the files are stored on and served by personal computers of the users. Most people who engage in file sharing are also downloading files that other users share. Sometimes these two activities are linked together. P2P file sharing is distinct from file trading in that downloading files from a P2P network does not require uploading, although some
networks either provide incentives for uploading such as credits or force the sharing of files being currently downloaded.
Web Based Sharing Webhosting for file sharing is also used. Since it is here very possible to exchange privately and in the very small communities also unpopular files can be
distributed very quickly and efficiently. Web hosters are independent from each other, therefore contents are not distributed further. Other terms for this are one-click hosting and web based sharing.
