With the advancement in technology, smartphones play an important role in our daily life. However,
                 the main function of the smartphones is telecommunication, but now with the help of apps, you

                 smartphones such as online bill payment, online shopping, video calling, message chat, and play
                 game.

                 What is an App?

                 An app is a software program primarily developed for hand-held smart devices such as mobile and
                 tablet. It helps the users 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 such as mobiles and tablets. 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 Googleʼs Play Store, Appleʼs App Store, and Microsoft's
                 Windows Store.

                 There are mainly three types of applications, which are:
                    Desktop: The application that is mainly developed for computer or laptop is called a desktop
                    application. This type of application depends on the hardware and operating system on which it
                    is going to use. It is usually developed for a particular operating system. Some of the examples of
                    desktop applications are Paint, Notepad, and Word.

                     Mobile: Mobile application (also known as mobile app) is software program that is developed
                    for hand-held devices such as smartphones and tablets. These apps are installed and run on
                    the device itself. Some examples of mobile apps are Camera, Calendar and Zoom.
                    Web: A Web app is an application program that is stored on a remote server and accessed over
                    the Internet through a Web browser interface. Some of the mobile apps and Web apps look and
                    work in the same way, with very little difference between them. However, these two are very
                    different from each other. One of the major differences is that the Web apps require an Internet
                    connection to work.
