                 With the advancement in technology, smartphones play an important role in our daily lives.

                 apps, you can do many things that were previously unimaginable on smartphones. You can
                 perform  various tasks on smartphones,  such as online bill payment,  online shopping,  video

                 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.
                 "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 from the 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 Microsoft Store is not in use for mobile devices. But you can download the
                 apps for your computer from the Microsoft Store.

                 There are mainly three types of applications, which are as follows:
                 •  Desktop: 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 examples of
                    desktop applications are Paint, Notepad, and Word.
