  • Browser applications typically require little or no disk space on the client

  • They require no upgrade procedure since all new features are implemented on the server and automatically delivered to the users


Benefits1
Benefits

  • Web applications integrate easily into other server-side web procedures, such as email and searching.

  • They also provide cross-platform compatibility in most cases (i.e., Windows, Mac, Linux, etc.) because they operate within a web browser window.
