The full name of tcp/ip is "Transmission Control Protocol/Internet Protocol", which means "Transmission Control Protocol/Internet Protocol" in Chinese. The TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol, the TCP protocol and the IP protocol The most representative, so it is called TCP/IP protocol.

TCP / IP introduction
The full name of tcp/ip is Transmission Control Protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol), which refers to A protocol suite that enables information transmission between multiple different networks.
TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol Among them, TCP protocol and IP protocol are the most representative, so they are called TCP/IP protocol.
Features:
The TCP/IP protocol can develop rapidly and become the de facto standard because it just adapts to the world In-range data communication needs. It has the following characteristics:
(1) The protocol standard is completely open, can be used by users for free, and is independent of specific computer hardware and operating systems.
(2) It is independent of the network hardware system, can run on the wide area network, and is more suitable for the Internet.
(3) Network addresses are uniformly allocated, and each device and terminal in the network has a unique address.
(4) High-level protocol standardization can provide a variety of reliable network services.
TCP/IP four-layer architecture
TCP/IP transmission protocol, namely transmission control/network protocol, also called network communication protocol. It is the most basic communication protocol used in networks. The TCP/IP transport protocol stipulates the standards and methods for communication between various parts of the Internet. Moreover, TCP/IP transmission protocols are two important protocols that ensure timely and complete transmission of network data information. The TCP/IP transmission protocol is strictly a four-layer architecture, including the application layer, transport layer, network layer and data link layer.
1. Network interface layer
In the TCP/IP protocol, the network interface layer is located on the fourth layer. Since the network interface layer merges the physical layer and the data link layer, the network interface layer is not only the physical medium for transmitting data, but also provides an accurate line for the network layer.
The physical layer defines some characteristics related to the interface of the transmission media, namely mechanical characteristics, electrical characteristics, functional characteristics, process characteristics, and needs to complete the conversion between parallel transmission and serial transmission.
The data link layer provides transparent and reliable data transmission services to users of this layer. Transparency means that there are no restrictions on the content, format and encoding of data transmitted on this layer, and there is no need to explain the meaning of the information structure; reliability means that during the transmission process, the physical connections that may be faulty provided by the physical layer are transformed into logical The specific methods of error-free data links include frame synchronization, error control, flow control, and link management.
The main broadband access technologies in the physical layer include CD protocol, Ethernet 802.3.
2. Internet layerThe Internet layer provides simple, flexible, connectionless, and best-effort datagram services to the upward value. The Internet layer does not provide quality of service commitments, that is, transmitted packets may be errors, lost, duplicated, and out of order, and certainly does not guarantee packet delivery time limits.
The main protocols in the Internet layer include IP protocol, Address Resolution Protocol ARP and Reverse Address Resolution Protocol RARP, and Internet Control Message Protocol ICMP.
The IP protocol is the core of the Internet layer. Through routing, the next hop IP is encapsulated and handed over to the network interface layer. IP datagrams are a connectionless service.
ICMP is a supplement to the Internet layer and can send back messages. Used to check whether the network is smooth (use the ping command).
ARP is to find the MAC address of the host through a known IP.
RARP determines the IP address through the MAC address.
3. Transport layerThe transport layer provides end-to-end logical communication between application processes, and has the function of multiplexing and demultiplexing, that is, the sender is different Any application process can use a transport layer protocol to transmit data; the transport layer of the receiver can correctly deliver the data to the destination application process after stripping off the header of the message. The transport layer will also perform error control on messages to improve reliable transmission.
The main protocols in the transport layer are User Datagram Protocol UDP and Transmission Control Protocol TCP
4. Application layer
The application layer provides applications for users.
The main protocols in the application layer include Domain Name System DNS, File Transfer Protocol FTP, Remote Terminal Protocol TELNET, Hypertext Transfer Protocol HTTP, Simple Mail Transfer Protocol SMTP, Mail Reading Protocol POP3 and IMAP, and Dynamic Host Configuration Protocol DHCP, Simple Network Management Protocol SNMP.
DNS: Provided Domain name resolution service, providing conversion between domain names and IP addresses, using port 53
FTP: transferring files between any computers in heterogeneous networks, using port 21
TELNET: providing users Remote login service, using port 23, using clear code transmission, poor confidentiality, simple and convenient
HTTP: used to realize various links on the World Wide Web, that is, the connection between the World Wide Web client program and the World Wide Web server, using port 80
SMTP/POP3, IMAP: Provides email transmission and is used to control the sending and transfer of letters. /Read mail from the mail server.
DHCP: Automatically assign IP addresses to computers newly added to the network.
SNMP: Managing software and hardware platforms produced by many manufacturers on the Internet

tcp/ip全称是“Transmission Control Protocol/Internet Protocol”,中文意思为“传输控制协议/网际协议”。TCP/IP协议不仅仅指的是TCP和IP两个协议,而是指一个由FTP、SMTP、TCP、UDP、IP等协议构成的协议簇,只是因为在TCP/IP协议中TCP协议和IP协议最具代表性,所以被称为TCP/IP协议。

区别:1、TCP/IP是一个协议簇,而OSI是一个模型;2、TCP/IP是五层结构,而OSI是七层结构;3、TCP/IP的第三层仅支持IP协议,OSI支持所有的网络层协议。联系:1、OSI引入了服务、接口、协议、分层的概念,而TCP/IP借鉴了OSI的概念;2、OSI先有模型,后有协议,先有标准,后进行实践,而TCP/IP先有协议和应用再提出了模型,且是参照的OSI模型。

如何利用PHP与TCP/IP协议进行数据通信引言:在现代互联网时代,数据通信是非常重要的一个方面。无论是客户端与服务器之间的通信,还是不同服务器之间的通信,TCP/IP协议一直是最常用的通信协议之一。本文将介绍如何利用PHP语言与TCP/IP协议进行数据通信,并提供相关的代码示例。一、TCP/IP协议简介TCP/IP协议是Internet协议簇的基础,它定义

TCP和IP是互联网中两个不同的协议:1、TCP是一种运输层协议,而IP是一种网络层协议;2、TCP提供了数据包的分段、排序、确认和重传等功能,而IP协议负责为数据包提供源和目标地址;3、TCP是面向连接的协议,而IP协议是无连接的;4、TCP还提供流量控制和拥塞控制。

应用层协议有:1、Telnet,允许一台机器上的用户,登录到远程机器上,并进行工作;2、FTP,提供了将文件从一台机器上移到另一台机器上的方法;3、SMTP,是一种提供电子邮件传输的协议;4、SNMP,是用于在IP网络管理网络节点的一种标准协议;5、DNS,主要用于将人们所熟悉的网址“翻译”成电脑可以理解的IP地址;6、HTTP,是一个请求-响应协议,用于在WWW上获取主页。

Go语言是一门不断发展壮大的编程语言,它被设计得非常适合实现高性能、可靠性和并发性等方面的网络应用程序。在使用Go编写TCP/IP协议相关的网络程序时,我们很容易遇到各种错误,而一些常见的TCP/IP错误也会给程序的调试带来一定的难度。本文将围绕着如何解决Go语言中的常见TCP/IP错误这一主题展开阐述。一、EOF错误EOF(EndOfFile)错误通常

“TCP/IP”协议是internet最基本的协议。TCP/IP(传输控制协议/网际协议)是一种网络通信协议,它规范了网络上的所有通信设备,尤其是一个主机与另一个主机之间的数据往来格式以及传送方式;TCP/IP协议是internet最核心也是最基本的协议,它严格来说是一个四层的体系结构,应用层、传输层、网络层和数据链路层都包含其中。

ip属于计算机网络体系结构的“网络层”协议。IP指网际互连协议,是TCP/IP体系中的网络层协议,它可以向传输层提供各种协议的信息,例如TCP、UDP等;对下可将IP信息包放到链路层,通过以太网、令牌环网络等各种技术来传送。
