Flashcards

What is the primary role of an operating system?

The OS acts as a bridge between applications and the hardware, managing resources and providing essential services for applications to run smoothly.

Monolithic Kernel

A monolithic kernel is a single, large program containing all core services. This design leads to high performance due to fewer context switches, but makes it difficult to debug and maintain.

Microkernel

In a microkernel design, most services run outside the kernel in user space, reducing the kernel's complexity. This approach offers better security and flexibility but potentially sacrifices some performance.
