Communication Apps

                 Communication apps allow us to communicate with each other  by sending and receiving
                 messages, information, and opinions in the form of texts, videos, and audios. These apps also
                 allow us to see the face of the person whom you are talking to.
                 The most commonly used communication apps Skype, Signal, and
                 FaceTime.

                 excellent shopping experience to its users. Some other examples of

                     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. So let's learn how to install an app from the

                         the  installation process will start
