A key part of kernel operation is communication with hardware devices inside and outside of the physical computer. However, it isn't practical for an OS to interact with every possible device in existence. Instead, kernels rely on the ability of device drivers, which add kernel support to spe...
A kernel is the essential foundation of a computer's operating system (OS). It's the core that provides basic services for all other parts of the OS. It's the main layer between the OS and underlying computer hardware, and it helps with tasks such as process and memory management, ...
