                  and tablet. 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 such as mobiles and tablets. Nowadays, 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 purchase.
                  The three most popular app stores are Google’s Play Store, Apple’s App Store, and Microsoft
                  Store.

                      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. Unlike desktop and mobile apps, Web apps do
                     not require installation and can be accessed from any device with an internet connection and
                     compatible Web browser.
