Network communication protocols, as the name suggests, are the protocols used for communication in computer networks and the standards for various network data transmission and other work, only one effective standard model can ensure that all kinds of services and services on the Internet can be completed in an orderly
, I think there are still few introductions, so I have consulted some other materials, I think the following description may be helpful for understanding this concept. Note: The original Article ).
I. loopback interface
To identify and manage network devices such as routers and PCs, we usually use the IP addresses configured on the interfaces of these devices, including physical interfaces and logical interfaces, such as VLANs. however, although the d
transmission, you can temporarily connect to Port 20 of the FTP server and use this port for data transmission.
FTP transmission mode: ASCII transmission mode and binary transmission mode. The difference between the two lies in whether the data is interpreted. The ASCII mode interprets the data, while the binary mode copies data one by one.3. Telnet protocol
Telnet is one of the earliest remote logon protocols.You can log on to a remote computer on the local machine using the Telnet protocol.
6.4 Configuring network ProtocolsThe database engine must have network protocols enabled before the client connects to the database engine. The SQL Server database engine can simultaneously enable multiple network protocols for the request service, and the client uses a sing

Note: The apache tomcat server must use port 8080.
I. URL
1. Basic Introduction
The full name of the URL is Uniform Resource Locator (Unified Resource Locator)
You can find the only one resource on the Internet through one URL.
A URL is the address and location of a r

This process begins with requesting the server to transfer the network files.Include a get command from the visible message, and when HTTP sends the initial GET command, TCP
Network protocol in the movie server occupies a very important position, it can be said that if there is no network protocol, the movie server will not function at all. This article briefly introduces several current mainstream network protocols, hoping to provide some help to understand the movie server.

Http is a Hyper Text Tansfer Protocol. All www files must comply with this Protocol standard.
Http is a protocol for browsing and transmitting data on the World Wide Web. It accesses remote network resources in the format of http: //

The data link layer has three main purposes:
* Sends and accepts IP data packets for the IP module;
* Send ARP requests to the ARP module and receive ARP responses;
* Send RARP requests and RARP responses to RARP.
The ARP protocol is mainly used to resolve the 32bit IP address to the MAC address (hardware address) corresponding to the 48bit (Ethernet ). The RARP protocol resolves the hardware address to an IP address. The two protocols are at the
Network protocols play an important role in movie servers. It can be said that without network protocols, movie servers will not be able to play a normal role. This article briefly introduces several mainstream network protocols,
Every time you write and design a network communication program, you always have to deal with the problem of customizing a set of application protocols (that is, communication protocols) and then writing corresponding methods to parse the protocols, and provides corresponding interfaces for upper-layer calls. It is eas

The driving force of technological development is the constant demand of people. With the increasing use of the Internet, the current network protocol version is no longer able to meet the needs of the times. Inevitably, we will launch a new generation of IPv6 network protocols that are more complete and have diverse functions. The inevitable elimination of IPv4
We all know that computer networks are divided into seven layers, each of which has its own network communication protocol. We can easily understand the concept of network communication protocol. However, it contains many protocols. Here we will summarize several important protocols to help you make a summary. See the
TPC/IP protocol is a Transport layer protocol, which mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data.Regarding the relationship between TCP/IP and HTTP protocol, the network has a relatively easy to understand introduction:"When we transmit data, we can only use the (Transport Layer) TCP/IP protocol, but in that case,
