P2P

     File sharing offers access to digital information or resources, which are documents, videos, images, and e-books. File sharing includes both private and public distribution of resources in social networking with different methods. Different types of file sharing are removable storage devices, centralized file hosting server installations on the network, hyperlinked documents, and P2P. 

    P2P is peer-to-peer file sharing, it's the most popular file-sharing method. P2P users locate shared data with third-party software. And P2P file sharing allows users to directly access, download, and edit files. However, P2P file sharing is controversial because it uses peer-to-peer software, and people concerned about their privacy issues. 

    P2P file sharing is popular and common, so there are many examples. First, P2P file sharing is used in lending music. As the article Peers Find Less Pressure Borrowing From Each Other said "The Internet has managed to disrupt many industries, from publishing to music. So why not lending?" The article also mentions that Google is building up the nation's largest peer-to-peer lender. Therefore, there is a huge lending club for providing convenience for people. The article Online Piracy and the Emergence of New Business Models shows the other example of P2P. It's Apple's iTunes online music service which has more than 200,000 songs from a wide range of artists and labels. There is no doubt that P2P is easy to be used, as the article describes iTunes that "The songs were offered in industry-standard Dolby Advanced Audio Coding format. which allowed for CD-quality sound and better data compression, and enabled users to hold more music and store files more quickly."
