A web application is a computer program that utilizes web browsers and web technology to perform tasks over the Internet.
How a Web Application Works
- User triggers a request to the web server over the Internet, either through a web browser or the application’s user interface
- Web server forwards this request to the appropriate web application server
- Web application server performs the requested task – such as querying the database or processing the data – then generates the results of the requested data
- Web application server sends results to the web server with the requested information or processed data
- Web server responds back to the client with the requested information that then appears on the user’s display
Example of a Web Application
Web applications include online forms, shopping carts, word processors, spreadsheets, video and photo editing, file conversion, file scanning, and email programs such as Gmail, Yahoo and AOL. Popular applications include Google Apps and Microsoft 365. Google Apps for Work has Gmail, Google Docs, Google Sheets, Google Slides, online storage and more. Other functionalities include online sharing of documents and calendars. This lets all team members access the same version of a document simultaneously.
Benefits of a Web Application
- Web applications run on multiple platforms regardless of OS or device as long as the browser is compatible
- All users access the same version, eliminating any compatibility issues
- They are not installed on the hard drive, thus eliminating space limitations
- They reduce software piracy in subscription-based web applications (i.e. SaaS)
- They reduce costs for both the business and end user as there is less support and maintenance required by the business and lower requirements for the end user's computer
Increased Internet usage among companies and individuals has influenced the way businesses are run. This has led to the widespread adoption of web applications as companies shift from traditional models to cloud-based and grid models. Web applications give businesses the ability to streamline their operations, increase efficiency, and reduce costs. These online apps such as email clients, word processors, spreadsheets, and other programs provide the same functionality as the desktop versions. However, they have an added advantage of working across multiple platforms, having a broader reach, and being easily accessible from anywhere.
