How do computers exchange information on the network? Just as we speak in a language, there is also a language between various computers on the network. This is the network protocol. Different computers must use the same network protocol for communication. Network protocols are a set of communication rules between all devices on the Network (network servers, computers, switches, routers, firewalls, etc, it specifies the format required for communication and the meaning of these formats. Most networks adopt a layered architecture. Each layer is built on its lower layer to provide certain services to its upper layer, the details of how to implement this service are blocked on the previous layer. The rules for communication between layer n on one device and layer n on the other device are layer n protocol. There are many protocols in each layer of the network. The protocol between the receiver and the sender must be the same. Otherwise, one party cannot identify the information sent by the other party. The network protocol enables various devices on the network to exchange information with each other. Common protocols include TCP/IP, IPX/SPX, and NetBEUI. Of course, there are also many network protocols. The specific protocol to choose depends on the situation. Computers on the Internet use the TCP/IP protocol. The main reason for the success of the ARPANET network is that it uses the TCP/IP standard network Protocol, TCP/IP (Transmission Control Protocol/Internet Protocol) ---- Transmission Control Protocol/Internet Protocol is a standard network protocol used by the Internet. It is a network architecture and protocol specification launched by ARPA from 1977 to 1979. With the development of Internet, TCP/IP has been further researched, developed, and applied, and has become a "common language" on Internet ".
