OPERATING SYSTEMS
The course will enable the students to
1. This module aims at making students learn about basic concepts of operating systems.
2. Describe & discuss various operating system workings like process management, memory management, concepts of concurrency control and disk management.
Course Outcomes (COs):
Course Outcome (at course level) | Learning and teaching strategies | Assessment Strategies |
|---|---|---|
The students will: CO47. Categorize the key functions of an operating system and assess the evolution of operating systems from primitive batch systems to sophisticated multi-user systems. CO48. Examine the concept of process states and review different schdeuling algorithms for a given scenario. CO49. Analyze different memory management techniques and compare virtual memory and main memory CO50. Categorize the conditions that cause deadloacks and assess deadlock prevention strategies related to each condition of deadlock CO51. Assess the principal techniques for file organization, access and allocation. | Approach in teaching: Interactive Lectures, Discussion, Tutorials, Reading assignments, Demonstration,
Learning activities for the students: Self-learning assignments, Effective questions, Simulation, Seminar presentation, Giving tasks. | Class test, Semester end examinations, Quiz, Solving problems in tutorials, Assignments, Presentation |
