The web-based software system consists of a set of web pages and components that interact to form a system which executes using web server(s), network, HTTP, and a browser, and in which user input affects the state of the system. Thus, web-based systems are typical software programs that operate on the Internet, interacting with the user through an Internet browser. Some other terms regarding these systems are given below:

Web page is the information that can be viewed in a single browser window.

A website is a collection of web pages and associated software components that are related semantically by content and syntactically through links and other control mechanisms. Websites can be dynamic and interactive.

A web application is a program that runs as a whole or in part on one or more web servers and that can be run by users through a website. Web applications require the presence of web server in simple configurations and multiple servers in more complex settings. Such applications are called web-based applications. Similar applications, which may operate independent of any servers and rely on operating system services to perform their functions, are termed web-enabled applications. These days, with the integration of technologies used for the development of such applications, there is a thin line separating web-based and web-enabled applications, so we collectively refer to both of them as web applications.
