P2P is short for English peer-to-peer (peer-to-peer), also known as "peer-to-peer ". "Peer-to-peer" technology is a new network technology that relies on the computing power and bandwidth of participants in the network, rather than gathering dependencies on a few servers. P2P is also short for point to point. It is a term for download, which means that while you download your own files, your computer will continue to upload files to the host, the more people there are, the faster the speed, but the disadvantage is that the hard disk is greatly damaged (read at the same time), there is a large amount of memory occupation, affecting the speed of the entire machine.
