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.

Context Switch

The process of switching between different programs or tasks running on the operating system.

Study Notes

Operating System Role

An operating system acts as an intermediary between applications and hardware.

Monolithic Kernel

A monolithic kernel's services operate within the same address space.
It offers high performance due to reduced context switching.
A monolithic kernel is challenging to debug and maintain.

Microkernel Design

In a microkernel design, most services are implemented in user space.
