Main Page | See live article | Alphabetical index The word kernel can mean more than one thing. The kernel of a seed is all that is within the outer coat of the seed, as the edible substance contained in the shell of a nut; hence, anything included in a shell, husk, or integument. The term kernel can also mean a single seed or grain, as "a kernel of corn". The kernel of an operating system is its essential component, such as the Linux kernel. In mathematics, kernel has several different, somewhat unrelated meanings; see Kernel (mathematics), or go directly to Kernel (function), Kernel (algebra), or Kernel (category theory).
