What is the basis for communication between different networks and computers on the internet?

The basis for communication between different networks and different computers in the Internet is "TCP/IP"; "TCP/IP" refers to "Transmission Control Protocol/Internet Protocol", which can be implemented between multiple different networks Protocol cluster for information transmission; TCP/IP protocol not only refers to the two protocols TCP and IP, but refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol Among them, TCP protocol and IP protocol are the most representative, so they are called TCP/IP protocol.

What is the basis for communication between different networks and computers on the Internet?

The basis for communication between different networks and different computers in the internet is TCP/IP.

TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) refers to a protocol suite that can realize information transmission between multiple different networks. The TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols. Just because in the TCP/IP protocol, the TCP protocol and the IP protocol The most representative, so it is called TCP/IP protocol.

Features

The TCP/IP protocol can develop rapidly and become the de facto standard because it just adapts to the world internal data communication needs. It has the following characteristics:

(1) The protocol standard is completely open, can be used by users for free, and is independent of specific computer hardware and operating systems.

(2) It is independent of the network hardware system, can run on the wide area network, and is more suitable for the Internet.

(3) Network addresses are uniformly allocated, and each device and terminal in the network has a unique address.

(4) High-level protocol standardization can provide a variety of reliable network services.
