Updated July 27, 20261 min readCited sources

A web application is software accessed through a web browser and run on a remote server. It is used over the internet without local installation.

What it is

A web application is an application software program delivered through a web browser and used over a network connection. It is stored on or runs from a remote server, with the browser acting as the user interface.

How it works

A user sends requests from a browser, the server processes those requests, and the application returns results to the browser for display. The browser handles the interface while server-side logic manages data and business rules.

Key details

Web applications are built with front-end technologies like HTML, CSS, and JavaScript, and back-end server code. They support interactive tasks such as email, shopping, forms, and social media. They are compatible across devices because they run in a browser. In Canada, web apps are widely used by businesses, government, and schools to deliver online services without local installation.

In short

  • Accessed through a browser, no installation needed.
  • Runs on a remote server, communicates over the web.
  • Interactive, supports user actions like login and data submission.
  • Compatible across multiple devices and operating systems.
Canadian angle

Web applications are widely used by Canadian businesses, governments, schools, and financial institutions to deliver services online through browsers, reducing the need for local software installation.
