Operating System

Objectives: In order to meet the ever increasing need of computers, study of operating system is compulsory. This is core
technology subject and the knowledge of which is absolutely essential for Computer Engineers. It familiarizes the students with
the concepts and functions of operating system. This subject provides knowledge to develop systems using advanced operating
system concepts.
To learn the evolution of Operating systems.

To study the operations performed by Operating System as a resource manager.
To study computer security issues and Operating System tools.
