
define what an operating system is and the role it plays

select appropriate operating system to get the required work done

identify the general architecture of operating systems

describe diversity of operating systems and portability

contrast and compare different types of operating systems

use shell scripts in function manipulation

identify how to manage and perform multiple tasks and sharing resources

recognize the need of security implementation in an operating system

practice different implementations for secure user authentication and system security
