Kernel

In a general knowledge context, a "kernel" refers to the core part of an operating system that manages system resources and communication between hardware and software. It acts as a bridge, ensuring that software applications can effectively use the computer's hardware, such as the CPU, memory, and input/output devices. By controlling these interactions, the kernel maintains system stability, security, and efficiency. In a broader sense, the term can also refer to the essential or fundamental part of any complex system or idea.
