What is web app ?


A web application or web app is any application software that runs in a web browser or is created in a browser-supported programming language (such as the combination of JavaScript, HTML and CSS) and relies on a common web browser to render the application.

Examples of web app 

Google Docs - it lets you create your documents (like Word), spreadsheets, presentations and more. It also allows you to collaborate and share documents. Its just an online Microsoft Office.


icloud - web operating system over the web. It is like bringing your own desktop and files running in your web browser that includes an office suite, media player, chat client, games, productivity tool, utility applications and more. Now you won’t worry that you are working in a different PC. 

Why do we need a web app ?


A desktop application is a self-contained program that performs a defined set of tasks under the user control whereas web app has no bounds.

—Easily Accessible - easily accessed from any computer or location that has Internet access. 

Desktop applications need to be individually installed on each computer, while web applications require a single installation.
