本文介绍了互联网中数据传输的基本过程，即数据包交换技术。当发送信息时，原始数据会被分割成多个小的数据包，通过路由器在网络中独立传输。到达接收端后，这些数据包再被重新组合为原始数据。文中还提到了两种关键协议：TCP/IP，它们负责数据包的拆分、路由及重组。

The Internet is a packet-switched network, which means that when you send information across the Internet from your computer to another computer, the data is broken into small packets. A series of switches called routers sends each packet across the Net individually. After all the packets arrive at the receiving computer, they are recombined into their original, unified form. Two protocols do the work of breaking the data into packets, routing the packets across the Internet, and then recombining them on the other end: The Internet Protocol (IP), which routes the data, and the Transmission Control Protocol (TCP), which breaks the data into packets and recombines them on the computer that receives the information.
