An application (App) is a software program designed to perform specific tasks for end users. Applications run on computers, mobile devices, or web browsers and provide functional tools for productivity, communication, entertainment, and services.

- A social media application lets users post content, chat, and interact with others.
- A web application, like an e-commerce site, enables online shopping and payments.
- A desktop application, such as a code editor, helps developers write and manage software.
