Android is a Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Initially developed by Android, Inc., whom Google financially backed and later purchased in 2005, Android was unveiled in 2007.

Android has been the best-selling OS worldwide on smartphones since 2011 and on tablets since 2013. As of May 2017, it has over two billion monthly active users, the largest installed base of any operating system, and as of June 2018, the Google Play store features over 3.3 million apps.[12] (Information taken from, and you can read more on the Android OS on wikipedia. accessed July 2018)

How do we use Android?

Each tablet will come with its own User Manual (or the manufacturer will provide access to a webpage and/or PDF). For those interested in some 'legacy material' you can read the 'Tablet PC_Android 4.0_User Manual.pdf' (in a 'Google Doc' of course!).

Google's own YouTube will provide plenty of video clips showing examples of Android use
