DCAP103 Principles of Operating Systems

Objectives: The objective of this course is to introduce the essential elements of operating systems. The organizati on andstructure
of modern operati ng systems and concurrent programming concepts will be discussed in the course. The knowledgeof operati
ng system plays signifi cant role in the program since it manages computer system resources and is essenti al to theireffi cient
use.
