Android vs iOS
Android and iOS are both operating systems
for cellular phones and tablets. Android runs
on a variety of phones and tablets, while iOS
runs exclusively on Apple iPhones and iPads
Operating System
Android is an Open Source project headed originally by Google, and now by the Open Handset Alliance. iOS is proprietary software developed by Apple, although it is built on top of some Open Source components, such as WebKit.
Android has an open framework to allow anybody to modify the operating system itself and to develop applications for it. Apple provides an SDK for the iOS that allows developers to access most of iOS's features, but is highly restricted.
Programs written for Android are usually written in java, although other languages also run on the JVM and host CPU. All applications released through the iPhone and iPad App Stores must be written in C, C++, Objective-C or Swift. It is rumored that Android's Dalvik virtual machine may eventually allow use with other bytecode languages like Python and Ruby.
