Homonym: Kernels (Nuts)
A kernel is the core component of an operating system that manages system resources and allows software applications to communicate with hardware. It acts as a bridge between the hardware and the user-level applications, ensuring that processes run smoothly and efficiently. The kernel handles tasks such as memory management, process scheduling, and device control.
There are different types of kernels, including monolithic kernels and microkernels. A monolithic kernel contains all the essential services in one large block of code, while a microkernel aims to run most services in user space, making it smaller and more modular. Each type has its advantages and trade-offs in terms of performance and complexity.
