The full name of tcp/ip is TCP/IP Protocol Suite or TCP/IP Protocols, where TCP refers to Transmission Control Protocol and IP refers to Internet Protocol Address.
The full name of TCP/IP is TCP/IP Protocol Suite or TCP/IP Protocols. Among them, TCP is Transmission Control Protocol, Transmission Control Protocol; IP is Internet Protocol Address, Internet Protocol Address.
Internet protocol is a network communication model and an entire network transmission protocol family, which is the basic communication architecture of the Internet. It is often commonly referred to as the TCP/IP protocol suite, or TCP/IP for short.
Due to the layered structure used in network communication protocols, when multiple levels of protocols work together, it is like a stack in computer science, so it is also called the TCP/IP protocol stack. These protocols first originated from the ARPAnet project of the US Department of Defense, so they are also called the DoD model.
Extended information:
The role of TCP/IP protocol:
The IP layer receives data packets sent by the lower layer (network interface layer such as Ethernet device driver) , and sends the data packet to the higher layer-TCP or UDP layer; conversely, the IP layer also transmits the data packet received from the TCP or UDP layer to the lower layer.
IP data packets are unreliable because IP does not do anything to confirm whether the data packet was sent in order or not corrupted. The IP data packet contains the address of the host that sent it and the host that received it. The address of the host.
TCP is a connection-oriented communication protocol. A connection is established through a three-way handshake. When the communication is completed, the connection must be removed. Since TCP is connection-oriented, it can only be used for end-to-end communication.
TCP provides a reliable data flow service, using "positive acknowledgment with retransmission" technology to achieve transmission reliability. TCP also uses a method called "sliding window" for flow control. The so-called window actually represents the receiving capability to limit the sending speed of the sender.
