Operating System Crash Course For Beginners - IGNOU Part - 1

Operating System Crash Course For Beginners - IGNOU Part - 1

This course is designed for:

• Students from Universities such as IGNOU

• People who are interested in learning the basics of Operating System Concepts.

The Course prepares especially those mature students who do not have enough time for studies because of their work schedule. The tutorial covers the important topics, concepts and questions asked in the previous few  IGNOU term-end examination papers.
