A server was needed to search for data by way of a search site, or even to connect it in the middle. Alternatively, P2P can share information with one another directly between people who connect to the same or related programs without needing such servers.

Unlike the traditional method of finding information on the web through a search engine, P2P (Peer) service is a service that allows users to receive information directly from all computers connected to the Internet, search and download.

This can extend the info extraction path, which was limited to the published website, to databases operated by individuals or companies. That is, managing your details nationally or globally?It really is operated, and not just various information sharing between members, but additionally communities among members who would like to share the same information can be formed, and teleconferencing and remote education could be possible through its role as a groupware.

In the U.S., in which a service that even shares multimedia files has emerged, a new company called http://lightshare.com is recently promoting e-commerce by means of a P2P service. The P2P will threaten search engines, publishers and auction sites, in the same way Napster and Soribada, which have been rippling since the Federal District Court made a decision to temporarily shut down Napster, a free online music file distribution site.

The reason for this increase in P2P’s popularity is that P2P services have exceeded the limitations of professional search services such as Yahoo, ensuring maximum anonymity and freedom of information communication. Furthermore, it can compensate for the shortcomings of e-commerce and secure reliable netizens as members without paying high advertising costs.

So far, Internet searches have been obtained by Internet users by accessing a specialist search company called a search engine and entering this issue language. Search engines have discovered the most appropriate information from millions of registered websites. Regardless of the fast and convenient service, the extracted information is bound to what is posted on the site and sometimes does not access the website.

In contrast, P2P extracts the desired files by searching the computers of individual users who have access to the Internet. Quite simply, it searches files on users’ computers which are currently connected to the Internet in real time, permitting them to download and access accurate and huge amounts of information if the required file is searched.

The most crucial technical implication of P2P may be the distribution of resources. Previously, files needed to be uploaded to a particular server and downloaded by all users. These models are significantly inefficient since they put more than necessary load on one server, however in the case of P2P, the load is distributed and efficient because they’re taken from each other.

If this means P2P from the user’s viewpoint, it is in the forming of an interactive community. It appeals to users that it is a lot more creative than the previous server-centered Internet since it allows them to get other users with exactly the same interests and directly interact with them through file sharing or chatting.
