The kernel of the simulator is the component that acts as the main controller of all decisions made by the system. In other words, the kernel is the server of the simulator system. Since the kernel is essentially the main processing unit, all components associated with the system must be linked to the kernel itself. In general, the main tasks performed by the kernel consist of the communication with all components, integrating the intended effects from each simulator onto the world, initiating and continuously creating the overall situation of the world's grid field during each round, storing and retrieving information from the world information database, deciding what information is to be displayed on the viewers, and assembling and updating all information to and from all other agents.

When used alone or as "KeyKOS Kernel" (as opposed to "security kernel"), refers to the privileged-mode code of the KeyKOS operating system. The kernel does not provide all of the function conventionally associated with an operating system, rather, it provides a set of tools which allow the majority of such function to be implemented by problem-mode (unprivileged) programs in domains. Specifically, the kernel provides the following: Primary objects. Multiprogramming support, primitive scheduling and hooks for more sophisticated schedulers running in domains. Single-level store. Virtual Memories for domains based upon the address segment using the Dynamic Address Translation hardware. Redundant disk storage for selected information (to provide reliability and improve read performance). A system-wide checkpoint-restart feature. Special pages exempt from checkpoint. Gate keys by which messages are sent between domains. Restricted access to individual I/O devices. An invariant interpretation of keys (independent of the location of the designated objects - whether on disk or in main storage). One of the single-level store facilities.
In the spatial domain, a kernel is a MxM operator which can be used in the convolution or multiplication with a NxN image to accentuate certain features or properties of an image. A kernel can also be represented in the frequency domain as a Fourier transform. Menu

The kernel, as the name suggests, is the 'core' of the operating system. It keeps all of the other components underneath it in check. It also handles other components of your computer - the hardware, for example. The kernel is the 'boss' of a machine.
the "kernel" of an operating system is the core section or sections that run in a privileged mode, performing the sorts of operations that you wouldn't normally want to let a user deal with - the idea is that the kernel is a secure, known piece of software which is allowed access everywhere, while other more experimental or replaceable parts of the OS can be limited to their own playpens - for example, if you are writing a driver for a new video card, it's nice to be certain that no matter how much the user lies to your software, he's still not going to be able to get it to write all over your hard disc! exactly what goes into the kernel varies greatly from OS to OS; NT4, for example, puts quite a lot of the OS into the kernel (including the video drivers!), while other "microkernels" may contain the bare minimum task and memory management
A component of the Knowbot Operating System (KOS), which encompasses the core functionality of a Knowbot Service Station (KSS).

The kernel can be contrasted with the shell, the outermost part of an operating system that interacts with user commands. Because the code that makes up the kernel is needed continuously, it is usually loaded into computer storage in an area that is protected so that it will not be overlaid with other, less frequently used parts of the operating system.
