What layers and main functions are included in the TCP/IP model?

The TCP/IP model consists of the following layers and main functions: the application layer directly provides services for your application process. The transport layer is responsible for providing services for communication between two host processes. The Internet layer is responsible for providing basic data packet transmission functions so that each packet can reach the target host. The Network Interface Layer receives and transmits IP data packets, receives physical frames from the network, extracts IP data packets, and transfers them to the next layer to manage the actual network media. There are two Cabling Standards for twisted pair wires: T568A and T568B. What is the standard cabling sequence for T568B? Orange white, orange, green white, blue, blue white, green, brown white, brown try to point out the common addresses of the computer network, and point out that they correspond to that layer. In a TCP/IP network, the physical address is related to the data link layer, and the logical IP address is related to the network layer, port address, and transport layer.
