4 Network Layer IP The transmission of packets mainly goes through Application Layer, Transport Layer, Network Layer, and Link Layer. Following the explanation of the application layer HTTP and Transport Layer TCP, the application layer data is encapsulated by the transport layer and then needs to be encapsulated by the network layer. The core task … Read more
1. Introduction to TCP/IP The IP protocol is the network layer, the TCP protocol is the transport layer, the HTTP protocol is the application layer, and socket is the code encapsulation and application of the TCP/IP protocol. TCP/IP mainly addresses how data is transmitted over the network, while HTTP mainly deals with how to package … Read more
1. TCP/IP Protocol Model TCP/IP Protocol (Transmission Control Protocol/Internet Protocol), includes a series of network protocols that form the foundation of the internet and is the core protocol of the Internet. The reference model based on TCP/IP divides the protocols into four layers: Network Interface Layer, Internet Layer, Transport Layer, and Application Layer. Exam Tips: … Read more
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
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
From: Non-Professional Class TCP/IP Concepts TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols that enables information transmission across multiple different networks. The TCP/IP protocol does not refer solely to the TCP and IP protocols, but to a suite of protocols including FTP, SMTP, TCP, UDP, IP, etc. It is the fundamental protocol of … Read more
