Detailed explanation-1: -Both the Mac OS X and iOS evolved from an earlier Apple operating system, Darwin, based on BSD UNIX.
Detailed explanation-2: -Apple (AAPL) iOS is the operating system for iPhone, iPad, and other Apple mobile devices. Based on Mac OS, the operating system which runs Apple’s line of Mac desktop and laptop computers, Apple iOS is designed for easy, seamless networking between a range of Apple products.
Detailed explanation-3: -iOS is actually an ARM variant of Darwin, derived from BSD, a UNIX-like kernel, and Apple’s own Mach kernel extension system. This is pretty different from Linux, which is a monolithic kernel, meaning all the driver code and I/O kit is part of the core kernel.
Detailed explanation-4: -The kernel of iOS is the XNU kernel. To learn about what “kernel” means in general, see the Wikipedia article. Pre-2.0, it was vulnerable to the Ramdisk Hack and may still be, but iBoot doesn’t allow boot-args to be passed anymore.
