Objective of the Course

The objective of the course is to make students aware of the functioning of a multi-user operating
system. This course will serve as a foundation course for the higher level course in Unix. The
students are expected to learn the commands while doing practical and emphasis should be
given to those switches/options and flags, which are most frequently used in real life.

After completion of the course students will be able to:

   • Understand Operating System concepts.
   • Use System calls and memory management.
   • Use Unix commands and editors.
   • Carry out Unix File management and shell programming in Unix.
   • Do Network configuration and security management in Unix.
