what is client

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The client (Client), also known as the user side, refers to the program that corresponds to the server and provides local services to customers. Except for some applications that only run locally, they are generally installed on ordinary clients and need to cooperate with the server to run.

After the development of the Internet, the more commonly used clients include web browsers used on the World Wide Web, email clients for sending and receiving emails, and client software for instant messaging. For this type of application, it is necessary to have corresponding servers and service programs in the network to provide corresponding services, such as database services, email services, etc. In this way, specific communication connections need to be established on the client and server sides to ensure normal operation of the application.

With the emergence of various types of tablets and smartphones, these devices are essentially miniaturized handheld computer devices with quite powerful network functions. Naturally, they have become a rapidly expanding main force in network clients.

Client type:

DNS client

When the user uses a domain name instead of an IP When accessing network resources using an address, the system will parse the domain name that needs to be accessed, that is, find the IP address corresponding to the domain name. First, the local domain name information cache is queried. If the query is successful, the corresponding IP address is returned, otherwise a DNS request is made to the local domain name server.

web client

Web client mainly refers to web browser (Browser). Its main function is to present the Web resources requested by the user from the server and display them in the browser window. Resources usually come in html, pdf, image and other formats. The mainstream web browsers include: Microsoft's IE, Mozilla's Firefox, Apple's Safari, Google's Chrome and Opera Software's Opera.

The main components of the browser include User Interface, Browser Engine, Rendering Engine, Networking, UI Backend, and JS interpreter (JavaScript), data storage (Data persistence), etc.

Game client

The game client is software that stores many resources in the game. Players input instructions through the client, and the client translates them into data and sends them to the server. After processing, the server gives the results, and then the client translates them into graphical representations and tells the players. It can be said that the client is an intermediary between the player and the server.

Mobile client

Mobile client takes mobile phones as an example. Mobile clients are software that can run on mobile terminals. It is also a key development project in the 3G industry and is of great significance.

With the advent of the 3G era, mobile Internet has slowly entered people's lives. When it comes to the future development trend of wireless Internet based on mobile phones, whether it is mobile client Internet access or mobile WAP Internet access, at this stage It is difficult for us to draw a conclusion prematurely, but one thing is certain, that is, the quality of user experience will directly determine the future and destiny of both.

Under wireless Internet network environment and various conditions, mobile client Internet access and mobile WAP Internet access have their own advantages and disadvantages. The client software needs to be installed on the mobile phone before it can be used; when using mobile WAP to access the Internet, you need to manually enter the URL for the first time. After saving the URL as a label, you can access it more conveniently.

It does take a certain amount of time to complete entering the URL on the mobile phone or to find the desired URL among the many saved tags. In addition to game clients, business application clients are gradually becoming familiar and used by everyone, bringing convenience to our lives and work.
