Architectures of Operating System
 

As and when the architecture of computer system evolves, architecture of the operating system also evolves and vice-versa.

Mainly, there are 4 types of architectures of operating system:

  1. Monolithic architecture : In the monolithic systems, each component of the operating system is contained within the kernel.

  2. Layered architecture : This is an important architecture of operating system which is meant to overcome the disadvantages of early monolithic systems
