Hi rajat07me, here is the sample you asked for concerning android vs Ios.
This are operating systems which are basically used in mobile phones and [url removed, login to view] being created in late 2003 while ios around 2006-2007 offer almost the same system but differ from points to to points. The latter have massive media and application support with the Ios supporting extremely high quality apps to android which is susceptible to low quality applications.
Simplicity is a key concern to many where I consider the Ios simpler to use as compared to android even though some features in the android make it more user friendly eg the widget feature in android which eases access to features eg bluetooth, wifi etc as compared to Ios where you have to access the settings app and on and on.
in conclusion, both systems function similarly in that they facilitate installation of apps that perform specific functions suitable to the user.
