Web application, computer program stored on a remote server and run by its users via a Web browser.

A Web application is an advantageous form of software because the use of browsers allows the application to be compatible with most standard computers and operating systems. Moreover, the application does not take up memory on a computer’s hard dive and is accessible from nearly any computer or device a person might use.

Multiple users can even use the same application at the same time, allowing for simultaneous participation. Although Web applications always require a network connection, this limitation has lessened in importance as the Internet has become more and more ubiquitous.
