Analysis of TCP/IP layer-4 protocol system and tcpip layer-4 Protocol TCP/IP layer-4 protocol system 1) The link layer, also known as the data link layer or network interface layer, usually includes the device driver in the operating system and the network interface card corresponding to the computer. They work togeth

Tcp/ip1. Basic conceptsWhy would there be TCP/IP ProtocolAll over the world, a wide variety of computers run their own different operating systems for everyone, and these computers are used in many ways when expressing the same message. It is as if God in the Bible has disturbed the accents of people everywhere and made them unable to cooperate. Computer users re

OSI Reference ModelOSI RM: Open Systems Interconnect Reference Model (open Systeminterconnection Reference Model)The OSI Reference model has the following advantages: Simplifies the related network operation; Provide compatibility and standard interface between devices; promote standardization work; The structure can be separated; Easy to implement and maintain. Since the 1960s, the computer network has been growing rapidly. In order to do

One; prefaceThe people who have learned the TCP/IP protocol have a feeling, this thing is too abstract, there is no data instance, after reading soon forget. This article will introduce an intuitive learning method, using the Protocol analysis tool to learn TCP/IP, in the process of learning to visually see the specifi

HTTP, FTP, SMTP, Telnet, etc. protocol, Oh! That HTTP protocol is the protocol that's used to access the Web. Actually ... You know, we should understand him from the reality, understand the function and function of the network protocol, and then from the fundamental point of view he is concrete how to achieve. We can start with HTTP, FTP, DHCP, DNS, ARP and other common protocols to understand how it works, and then follow this attitude to further understand the other protocols. Let's get down

TCP/IP RoamingTCP/IP is the foundation of the Internet Protocol stack, which includes dozens of large and small protocols. This article is mainly related to HTTP, TCP, IP protocol. We often learn that the network model is seven or five layers, in fact, it is generally believ

TCP/IP is the communication protocol of the Internet. A communication protocol is a description of the rules that a computer must obey, and the computer can communicate only if the rules are followed. Both the browser and the server are using TCP/IP Both Internet browsers and Internet services use

Internet technology in wireless networks. At the same time, the huge interconnectivity of the global Internet is a great incentive. Because small devices such as sensors are often required to be small and cheap, the implementation of network protocols must handle limited computing resources and memory. This article describes the design and implementation of a small TCP/IP protocol stack that becomes LWIP.

Embedded Network sensor: sensitive unit, intelligent Processing Unit and TCP/IP communication protocol interface Sensor operating mechanism: the sensor will be measured by the physical volume into electrical signals, through the ad conversion to digital signal, after the microprocessor data processing, the results are transmitted to the network; the data exchange with the network is done by the

T

TCP/IP is a shorthand for the "transmission Control protocol/internet Protocol", the Chinese translation is the Transmission Protocol/Internet Protocol. TCP/IP is not a protocol, but a generic term for a protocol cluster. It is the foundation of today's Internet and it is important for programmers to understand it. Tal

TCP/IP OverviewTCP/IP is generally considered to be a four-layer protocol: Link layer. Also known as the data Link layer or network interface layer, including device drivers and network interface cards, which work together with the physical interface details of the cable.

The TCP/IP protocol is actually a set of protocols, including many protocols, which constitute the TCP/IP protocol stack. But the Transmission Control Protocol (TCP) and the Internet Protocol (IP) are the most important of them, e
