As we all know, the TCP/IP model is the foundational model for most network communications today, and its basic function is to define the technical framework for interconnecting devices. Through it, networks around the world can interconnect, and information can be exchanged globally. The protocol stack is also known as the communication stack. When we … 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
Preface Network Protocols When we connect to the internet using our mobile phones, we use many network protocols. Starting from connecting the phone to WiFi, the 802.11 (i.e., WLAN) protocol is used to access the network; the phone automatically obtains network configuration using the DHCP protocol, and only after obtaining the configuration can the phone … Read more

1. Architecture The TCP/IP protocol suite is a four-layer protocol system. Figure 1 TCP/IP Architecture Data Link Layer: Implements the network driver for the network interface card, handling the transmission of data over physical media (Ethernet, Token Ring). The network driver abstracts the electrical characteristics of different physical networks. The data link layer uses ARP … Read more
Finally, I have come to the TCP protocol, which is the most important and exciting part of TCP/IP detailed explanation, and it requires significant effort to read. Brief Introduction TCP and UDP are at the same layer— the transport layer. However, the most significant difference between TCP and UDP is that TCP provides a reliable … Read more
