What is a CGI program? What is CGI A basic understanding of the concept and role of CGI?

A type of programmatic coding of a web page.

CGI technology is widely used, it can be used for the implementation of login, registration, search, shopping cart and other functions, and can also be used for statistics, data analysis, security detection and other aspects.

CGI is a general-purpose gateway interface that is a standard for the interface between a web server and a web application. It is a technology that interacts with a web server and a web application, which can make the web server dynamically generate HTML pages and realize the interactivity of the web application.

CGI technology is widely used, it can be used for the implementation of functions such as login, registration, search, shopping cart, etc., and can also be used for statistics, data analysis, security testing, etc.

CGI is a universal gateway interface that is an interface standard between a web server and a web application. It is a technology that interacts with a web server and a web application, which can make the web server dynamically generate HTML pages and realize the interactivity of the web application.

In short, CGI technology is an indispensable part of web development, which can help web applications realize the functions of dynamic web pages, improve user experience, and bring more convenience and flexibility to web development.

The role of CGI is to pass the user's request to the web application, and the web application will return the result to the web server after the web application is processed, and the web server will return the result to the user. In this way, users can interact with the web application through the web page to realize the function of a dynamic web page.

CGI and CG areas are different in nature, origin, and purpose.

First, the nature is different.

1. CGI: It is an important Internet technology that allows a client to request data from a web browser to a program executed on a web server.

2. CG: refers to computer graphics, which is a science that uses mathematical algorithms to convert two-dimensional or three-dimensional graphics into raster forms of computer monitors.

Second, the origin is different.

1. CGI: Originated in 1993 by the National Supercomputer Slag Hengchen Application (NCSA) for the NCSA httpdweb server.

2. CG: Originated in January 1963, Sutherland, a 24-year-old at MIT Lincoln Laboratory, completed his Ph.D. in graphics systems for human-computer communication.

Third, the purpose is different.

1. CGI: CGI is designed to be independent of any language. It can be implemented in any scripting language or in a completely stand-alone programming language, as long as the language can run on the system.

2. CG: CG aims to create effective visual communication. In the field of science, graphics can present scientific results to the public in a visual way.

If you're talking about **, then I shouldn't be wrong......

CG stands for Computer Graphics, a science that uses mathematical algorithms to convert two- or three-dimensional graphics into raster form of a computer monitor. It also refers to the animation made with CG technology in some ** games, also known as CG cutscenes. Computer animation is a technique used to create animation with the help of a computer.

There are many forms of computer animation, but they can be roughly divided into two types: two-dimensional animation and three-dimensional animation.

CGI is a computer-synthesized image, that is, three-dimensional animation, three-dimensional animation software first establishes a virtual world in the computer, and the designer establishes a model and scene in this virtual three-dimensional world according to the shape and size of the object to be represented, and then sets the movement trajectory of the model, the movement of the virtual camera and other animation parameters according to the requirements, and finally assigns a specific material to the model as required, and lights are added. When all of this is done, the computer can automatically calculate and generate the final picture.

To get back to the point, CGI belongs to the category of CG, that is, CGI is a form of CG.
