Introduction to Web Application

Millions of businesses use the Internet as a cost-effective communication channel. It lets them exchange information with their target market and make fast, secure transactions. However, effective engagement is only possible when the business is able to capture and store all the necessary data and has a means of processing this information and presenting the results to the user.

Web applications use a combination of server-side programs to handle the storage and retrieval of the information, and client-side scripts to present information to users. 

This allows users to interact with the company using online forms, content management systems, shopping carts, and more. 

In addition, the applications allow employees to create documents, share information, collaborate on projects, and work on standard documents regardless of location or device.

How does it work?

---

Web applications are usually coded in browser-supported languages such as JavaScript and HTML; these languages rely on the browser to render the program. 

Some of the applications are dynamic, requiring server-side processing. Others are entirely static with no processing needed for the server.

The web application requires a web server to manage requests from the client, an application server to perform the tasks requested, and, sometimes, a database to store the information.

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.
