Information transmission mode:

Generally speaking, the network is divided into five layers from top to bottom: application layer, transport layer, network layer, data link layer and physical layer. Each layer has its own rules, which are called "protocols". TCP/IP protocol is one of the most commonly used network protocols.

The network cable belongs to the physical layer in the network. According to these protocols, the data to be transmitted in the computer is decomposed into packets (including the addresses of the local computer and the destination computer), and finally transmitted to the destination computer through the network cable according to certain principles, just like the principle of transmitting electricity through the wire, except that the pulse electric signal is transmitted on the network cable, which follows certain rules.
