什么是 P2P？ P2P 代表 “Peer-to-Peer”（点对点），意味着设备之间的直接通信。 在传统的互联网设置中，你首先将文件上传到服务器，然后另一台设备再从该服务器下载。 通过 P2P，设备可以相互连接并在彼此之间直接传输数据。虽然中心服务可能仍会帮助设备相互发现并建立连接，但实际的数据传输可以直接在设备之间进行。 这一理念的根源可以追溯到 20 世纪 70 年代开发的分布式计算机系统。P2P 在 1999 年随着 Napster 的出现而广为人知，Napster 允许用户相互分享存储在自己电脑上的文件。 随后，Gnutella 和 BitTorrent 等系统将这一理念推向了更深层次。如今，P2P 不仅用于文件共享，还用于通信、内容分发、协作以及许多其他分布式应用。 File Transfer 以最简单的形式采用了相同的理念：连接两台设备，选择文件，直接发送到另一台设备。
What is P2P? P2P stands for "Peer-to-Peer," meaning direct communication between devices. In a traditional internet setup, you first upload a file to a server, and the other device then downloads it from that server. With P2P, devices can connect to each other and transfer data directly between them. A central service may still help the devices find and connect to each other, but the actual data transfer can happen directly between the devices. The roots of this idea go back to distributed computer systems developed in the 1970s. P2P became widely known in 1999 with Napster, which allowed users to share files stored on their own computers with one another. Later, systems such as Gnutella and BitTorrent took the idea much further. Today, P2P is used not only for file sharing, but also for communication, content distribution, collaboration, and many other distributed applications. File Transfer uses the same idea in its simplest form: connect two devices, choose your file, send it directly to the other device.
