Operating Systems

(Theory)

 

CO55. Categorize the key functions of an operating system and assess the evolution of operating systems from primitive batch systems to sophisticated multi-user systems.

CO56. Examine the concept of process states and review different scheduling algorithms for a given scenario.

CO57. Assess the significance of process synchronization and evaluate deadlocks formation and handling deadlock Mechanism.

CO58. Analyse different memory management techniques and compare virtual memory and main memory.

CO59. Assess the principal techniques for file organization, access and allocation.

CO60. Contribute effectively in course-  specific interaction.
