What is a web application?

• A. A software installed directly on a computer
• B. A mobile application designed for smartphones
• C. A software application that runs on a web server
• D. A desktop software with offline capabilities

Answer: (C)

A web application is defined as a software application that runs on a web server, which means it is accessed through a web browser over a network, typically the Internet. Users interact with web applications by entering data or commands via the web interface, and the application processes that information, often connecting to databases and other resources located on the server.

This model allows web applications to be platform-independent since they do not require installation on individual devices, enabling users to access the application from any device with an internet connection and a web browser. Given the rise of cloud computing and remote access, web applications have become a vital part of modern computing, offering features such as real-time updates and collaborative tools that can be utilized simultaneously by multiple users.

The other options highlight software applications that are designed for specific environments: software installed directly on a computer is typically referred to as desktop software, a mobile application specifically targets smartphones and tablets, and desktop software with offline capabilities is designed to function without an internet connection. None of these captures the essential nature of a web application, which is distinguished by its server-side execution and accessibility via the web.
