At present, most WEB applications combine server and client, among which there are many client applications, such as browsers. The server basically adopts the structure of "server hardware+server software +WEB application", and Web application is the core part of the server.
1990, Berners-Lee made CERN's phone book into the first WEB application, and ran this application on his own computer. At the same time, Berners-Lee named this application World Wide Web (WWW). WEB applications are divided into static applications and dynamic applications.
Introduction of Web application products
There are two application modes: C/S and B/S. C/S is a client/server program, which means that such programs generally run independently. B/S is a browser/server application, which is usually run by a browser such as IE.
WEB applications are generally in B/S mode. Web application is an "application" at first, which is not essentially different from programs written in standard programming languages such as C and C++. However, Web application is unique, that is, it is based on the Web, rather than using traditional methods to run. In other words, it is the product of a typical browser/server architecture.
