This is a term for the computing elite, so proceed with caution. Today's operating systems are built in "layers". Each layer has different functions such as serial port access, disk access, and the user interface itself. The base layer, or the foundation of the operating system, is called a kernel. The kernel provides low-level services, such as the hardware-software interaction and memory management -- much like a kernel of corn. Or not.
