Application

An application, often shortened to app, is a program or set of programs that allows end users to perform particular functions. For example, e-commerce companies provide applications to customers to facilitate purchases and service. An application is also a type of software, and in fact, is sometimes called application software. Like other software, an application is made of a program, or set of programs, but not every type of software or program is an application. What makes an application unique is that it’s designed to interact with the end user of the computer or device; it helps the user perform certain tasks. Because applications are built for users, they have a graphical user interface—where the user interacts with the application.
