WHAT IS AN APP?
An app is a software program primarily developed for hand-held smart devices such as mobile and
tablet. It helps them perform their personal and professional tasks more effectively. The app is a modern
term derived from the word application. Generally, the word app is used to refer to the applications on
smart devices such as mobiles and tablets. Thousands of apps are available for smart devices. Most of
the apps are freely downloadable. However, some of the apps need to be purchased from the app store.
The three most popular app stores are Google's Play Store, Apple's
App Store, and Microsoft Store. However, the Microsoft Store is not
in use for mobile devices. But you can download the apps for your
computer from the Microsoft Store.
The three main types of applications are as follows:
Desktop Applications: The application that is mainly developed for a computer or laptop is called
a desktop application. This type of application depends on the hardware and operating system
on which it runs. It is usually developed for a particular operating system. Some of the examples of
desktop applications are Paint, Notepad, and Word.
Mobile Applications: The software program that is developed for hand-held devices such
as smartphones and tablets is called a Mobile application (also known as a mobile app).
