Communication Apps

                 Communication apps allow us to communicate with each other  by sending and receiving
                 messages, information, and opinion in the form of texts, videos, and audios. These apps also
                 allow us to see the face of the person whom you are talking.

                 The most commonly used communication apps  Skype,  Google
                 Meet, and FaceTime.
                 E-Commerce Apps

                 apps allow us to buy or sell products while sitting at home or any other place.
                 Amazon is the leading online marketplace  which provides an
                 excellent shopping experience to their users. Some other examples
                 of the E-commerce apps are Paytm and Blinkit.


                     DOWNLOADING AND INSTALLING THE APP

                 As you already know that an app is a software program. Hence, to use any app, you need to first
                 install it on your mobile device. As we have already learned, Google’s Play Store and Apple’s App
                 store are the most commonly used app stores. Among these two, Google’s Play Store is more
                 popular due to the huge market of Android devices give a
                 space before. So we are taking an example of an Android
                 device to install an app from the Google’s Play Store.

                 To  download  and  install an  app  on  an  Android device,
