Linux-based is which of the following operating system?
Android is a mobile operating system based on a modified Linux kernel. A kernel may be thought of as the operating system's brain. The type of kernel used in an operating system determines the kind of operating system. The Linux kernel is used by all Linux flavors, the Windows NT kernel is used by all Windows editions, and Apple's XNU kernel is used by iOS and macOS (XNU itself is based on Unix). Isn't it simple?
