1. What isAndroid  Operating System ?

Android is the mobile operating system developed by Google. Essentially, Google produces the software that runs almost every other mobile phone besides Apple’s iPhone. There are also some popular Android tablets as well. Android is a Linux-based software system, and similar to Linux, is free and open source software. This means that other companies can use the Android operating system developed by Google and use it in their mobile devices (more on that later). The distinguishing factor of this brand is a kernel. Android hosts a central core, which essentially is a strip code that helps the software operate.
