                        DEFINING THE ANDROID AND IOS


                 Nowadays, most of the mobile devices run on Android and iOS.


                 Android

                 Android is an operating system for mobile devices developed by Google. It is the most

                 commonly used operating system in mobile devices. Google and some other mobile
                 manufacturing  companies use the Android  as operating system for their devices.
                 Android  provides  an  easy to  use  and  friendly  environment  to  their  users. The  user   Android
                 interface of an Android mobile is look like this:

                 iOS

                 iOS (formerly iPhone OS) is also a popular operating system developed by Apple Inc. for
                 its hand-held devices such as iPhone and iPad. The user interface of the iOS looks very
                 professional as shown:

                        TYPES OF MOBILE APPS

                 Apps provide specific functionality  to your mobile and tablet devices in a more  simple and
                 user-friendly manner. We use so many apps on our mobile device to perform different types of
                 tasks. Generally, these apps can be divided into three types, which are, native, web and hybrid. Let
                 us learn about these in detail:


                 Native Apps

                 Native apps are platform dependent, which means that these apps are primarily developed for a
                 specific platform. For example, any app developed for iOS will not run on any other platform such
                 as Android and Windows. In other words, you cannot install the app developed for the Android
                 platform on an iOS platform. Most of the apps installed on your mobile device are native apps.
                 These apps are distinctly accessible from app stores and offer the fastest, most reliable and most
                 responsive experience to users.
                 Some of the examples of native apps are  Camera,
                 Microphone,  Gallery and  Address book. However, there
                 are some alternatives also available for these apps but using
                 native apps is easiest.

                 Web Apps

                 Web-based  apps on mobiles are applications  that are accessed through  a mobile device's
                 web  browser rather than  being  downloaded  and  installed  from an  app  store. These  apps  are
                 designed to be responsive, meaning they adapt to different screen sizes and orientations, providing
                 a mobile-friendly experience.
