  1. Kernel

    In computing, the kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources. Usually, as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources that application software must control to perform its function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls. Operating system tasks are done differently by different kernels, depending on their design and implementation. While monolithic kernels execute all the operating system code in the same address space to increase the performance of the system, microkernels run most of the operating system services in user space as servers, aiming to improve maintainability and modularity of the operating system. A range of possibilities exists between these two extremes.
