This article organizes knowledge related to the TCP-IP protocol through two diagrams. The TCP communication process includes three steps: establishing a TCP connection channel, transmitting data, and disconnecting the TCP connection channel. As shown in Figure 1, a schematic diagram of the TCP communication process is provided. Figure 1 TCP Three-Way Handshake and Four-Way Disconnect … Read more
The TCP/IP protocol is a transport layer protocol that mainly addresses how data is transmitted over the network, while HTTP is an application layer protocol that mainly deals with how to package the data. Regarding the relationship between TCP/IP and HTTP protocols, there is a relatively easy-to-understand introduction on the internet: “When we transmit data, … Read more
TCP/IP is not a single protocol, but a collective term for a suite of protocols. It includes the IP protocol, ICMP protocol, and TCP protocol. 1 Here are a few key points to note: Internet Address: This is the IP address, generally consisting of the network number + subnet number + host number.Domain Name System: … Read more
