Operating Systems

Objective:
The course is designed with an objective to
 Discuss and explain the basic concepts of Operating System, process management,
memory management, file management, Input / Output management and the potential
problem of deadlocks.

Learning Outcome:
On completion of the course, students will be able to
 Describe the general architecture of computers,
 Describe, contrast and compare differing structures for operating systems,
 Analyze theory of processes, resource control (concurrency etc.), physical and virtual
memory, scheduling, I/O and files
 Implementing shell programming
