How many protocols are tcp/ip?

tcp/ip refers to a protocol cluster composed of Telnet, FTP, SMTP, UDP, TCP, ICMP, IP, IGMP, ARP, RARP and other protocols, just because in the TCP/IP protocol, the TCP protocol and The IP protocol is the most representative, so it is called TCP/IP protocol.

TCP/IP (Transmission Control Protocol/Internet Protocol) refers to a protocol that can transmit information between multiple different networks cluster. 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.

TCP/IP transmission protocol, namely transmission control/network protocol, is also called network communication protocol. It is the most basic communication protocol used in networks. The TCP/IP transport protocol stipulates the standards and methods for communication between various parts of the Internet. Moreover, TCP/IP transmission protocols are two important protocols that ensure timely and complete transmission of network data information. The TCP/IP transmission protocol is strictly a four-layer architecture, including the application layer, transport layer, network layer and data link layer. [2]

TCP/IP protocol is the most basic protocol of the Internet. The main protocols of the application layer include Telnet, FTP, SMTP, etc., which are used to receive data from the transport layer or according to different application requirements and methods. Transmit data to the transport layer; the main protocols of the transport layer are UDP and TCP, which are channels for users to use the platform and the internal data of the computer information network to achieve data transmission and data sharing; the main protocols of the network layer are ICMP, IP, IGMP is mainly responsible for the transmission of data packets in the network; the network access layer is also called the network interface layer or data link layer. The main protocols are ARP and RARP. Its main function is to provide link management error detection and control of different communication media. Issues related to information details are effectively handled.
