In-Depth Guide to Communication Protocols

TCP HTTP UDP: All are communication protocols, which are the rules followed during communication. Only when both parties “speak” according to these rules can they understand or serve each other. Relationship Between TCP, HTTP, and UDP: TCP/IP is a suite of protocols, divided into four layers: network interface layer, network layer, transport layer, and application … Read more

A Comprehensive Summary of TCP

/ Network Layered Structure / Consider the simplest case: communication between two hosts. At this point, only a single network cable is needed to connect the two, specifying their hardware interfaces, such as both using USB, 10v voltage, and 2.4GHz frequency. This layer is the physical layer, and these specifications are the physical layer protocol. … Read more

Detailed Explanation of TCP/IP Port Numbers in Networking

In network technology, a port generally has two meanings: first, it refers to the physical interface (hardware) between computers and other devices. For example, interfaces like RJ-45 ports and SC ports used to connect other network devices such as switches and routers. Second, it refers to the logical virtual ports (software), which typically refer to … Read more
