The kernel is the core piece of most operating systems. It is a piece of software responsible for the communication between hardware and software components. As a basic component of an operating system, a kernel provides abstraction layers for hardware, especially for memory, processors and communication between hardware and software. It also provides software facilities such as process abstractions and makes interprocess communication easier.
