MASTER OF COMPUTER APPLICATION

     SEMESTER: III      

  

Subject Name: Operating System (OS)
Subject Code: 630004

Objective:

• To provide an understanding of the basic concepts of modern OS. Describe the role and purpose of

OS.

• To understand the concept of the interaction between user application, OS and hardware architecture.

• To provide an understanding of concept of process, concurrency problems. Using these concepts,

learners can develop effective parallel applications/Programs.

• To give an understanding of the concept of deadlock prevention, avoidance, detection and recovery

for identification of solution strategies.

• To understand the issues involved with preemptive vs nonpreemptive scheduling.

• To study the concept of management of memory, disk and file. Students can understand the efficient

use of primary and secondary storage for their application.

• To provide an understanding of security and protection in OS and distributed applications.
