Kernel<p>The kernel is a computer program that is the core of a computer's operating system, with complete control over everything in the system. On most systems, it is one of the first programs loaded on start-up (after the bootloader). It handles the rest of start-up as well as input/output requests from software, translating them into data-processing instructions for the central processing unit. It handles memory and peripherals like keyboards, monitors, printers, and speakers.</p> <p>See also: <a href="https://en.wikipedia.org/wiki/Kernel_(operating_system)">Kernel </a></p>
