In the Internet protocol, ip refers to the Internet Protocol, which is the core of the entire TCP/IP protocol family and the basis of the Internet; tcp refers to the transmission control protocol, which is a connection-oriented A reliable, byte stream-based transport layer communication protocol. The purpose of designing IP is to improve the scalability of the network: first, to solve Internet problems and realize the interconnection of large-scale and heterogeneous networks; second, to separate the coupling relationship between top-level network applications and underlying network technologies to facilitate the two. Develop independently.

In Internet protocols, ip refers to the Internet Protocol (Internet Protocol), and tcp refers to the Transmission Control Protocol (Transmission Control Protocol).
ip protocol
IP is the abbreviation of Internet Protocol and is the network layer protocol in the TCP/IP system. The purpose of designing IP is to improve the scalability of the network: first, to solve Internet problems and realize the interconnection of large-scale and heterogeneous networks; second, to separate the coupling relationship between top-level network applications and underlying network technologies to facilitate the two. Develop independently. According to the end-to-end design principle, IP only provides a connectionless, unreliable, best-effort packet transmission service to the host.
IP is the core of the entire TCP/IP protocol suite and the foundation of the Internet. IP is located in the network layer of the TCP/IP model (equivalent to the network layer of the OSI model). The upper layer can carry information of various protocols in the transport layer, such as TCP, UDP, etc.; the lower layer can put IP information packets into the link layer. , transmitted through various technologies such as Ethernet and Token Ring networks.
In order to adapt to heterogeneous networks, IP emphasizes adaptability, simplicity and operability, and makes certain sacrifices in reliability. IP does not guarantee the delivery time and reliability of packets. The transmitted packets may be lost, duplicated, delayed or out of order.
tcp protocol
Transmission Control Protocol (TCP, Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. Defined by IETF's RFC 793.
TCP is designed to accommodate a layered protocol hierarchy that supports multiple network applications. TCP is relied upon to provide reliable communication services between pairs of processes in a host computer connected to different but interconnected computer communication networks. TCP assumes that it can obtain simple, possibly unreliable datagram services from lower-level protocols. In principle, TCP should be able to operate on top of a variety of communications systems, from hardwired connections to packet-switched or circuit-switched networks.
