                    WHAT IS AN APP?

                 An app is a software program primarily developed for hand-held smart devices such as mobiles
                 and tablets. It helps the user to 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 the applications on smart devices. Thousands of apps are available for smart devices.
                 Most of the apps are freely downloadable from app store. 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 Windows Store is not in use for mobile devices. But you can download the
                 apps for your computer from the Windows Store.

                     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 type of
                    operating system on which it runs. Some of the examples of desktop applications are Paint,
                    Notepad and Word.

                    and Facebook Messenger.
