Network data operation principle

A computer network consists of many computers. In order to transmit data between computers on the network, two things must be done, namely, the destination address of data transmission and measures to ensure fast and reliable data transmission. This is because data is easy to be lost or transmitted incorrectly during transmission, and the Internet uses special computer language (protocol) to ensure that data can reach the designated destination safely and reliably.
