Monolithic Kernel

A monolithic kernel is the core part of an operating system that manages all system resources and hardware directly in a single, large block of code. It includes essential services like process management, memory management, and device drivers, all running in the same space. This design allows for fast communication between components since they are all integrated, but it can be more complex and less flexible than other architectures, like microkernels, where functions are more modular and separated. Overall, a monolithic kernel can lead to better performance but may pose challenges in terms of maintenance and stability.
