Course objectives:
This course will enable students to:
Understand the services provided by an operating system.
Explain how processes are synchronized and scheduled.
Understand different approaches of memory management and virtual memory
management. Describe the structure and organization of the file system
Understand interprocess communication and deadlock situations.
Teaching-Learning Process(General Instructions)
The samples strategies, which the teacher can use to accelerate the attainment of the various
course outcomes are listed in the following:
1. Lecturer method (L) need not to be only traditional lecture method, but alternative effective
teaching methods could be adopted to attain the outcomes.
2. Use of Video/Animation to explain functioning of various concepts.
3. Encourage collaborative (Group Learning) Learning in the class.
4. Ask at least three HOT (Higher order Thinking) questions in the class, which promotes critical
thinking.
5. Adopt Problem Based Learning (PBL), which fosters students’ Analytical skills, develop
design thinking skills such as the ability to design, evaluate, generalize, and analyze information
rather than simply recall it.
6. Introduce Topics in manifold representations.
7. Show the different ways to solve the same problem and encourage the students to come up
with their own creative ways to solve them.
8. Discuss how every concept can be applied to the real world - and when that's possible, it helps
improve the students' understanding.

Assessment Details (both CIE and SEE)
The weightage of Continuous Internal Evaluation (CIE) is 50% and for Semester End Exam (SEE)is
50%.The minimum passing mark for the CIE is 40%of the maximum marks(20marks out of 50) and for
the SEE minimum passing mark is 35% of the maximum marks (18 out of 50 marks). The student is
declared as a pass in the course if he/she secures a minimum of 40% (40 marks out of 100) in the sum
total of the CIE (Continuous Internal Evaluation) and SEE (Semester End Examination) taken together.
Continuous Internal Evaluation:
There are 25marks for the CIE's Assignment component and 25 for the Internal Assessment Test
component.
Each test shall be conducted for 25marks.The first test will be administered after 40-50% of the
coverage of the syllabus, and the second test will be administered after 85-90% of the coverage of the
syllabus. The average of the two tests shall be scaled down to 25 marks
Any two assignment methods mentioned in the 22OB2.4, if an assignment is project-based then only
one assignment for the courses hall be planned. The schedule for assignments shall be planned
properly by the course teacher. The teacher should not conduct two assignments at the end of the
semester if two assignments are planned. Each assignment shall be conducted for 25 marks. (If two
assignments are conducted then the sum of the two assignments shall be scaled down to 25 marks)
The final CIE marks of the course out of 50 will be the sum of the scale-down marks of tests and
assignment/s marks.
Internal Assessment Test question paper is designed to attain the different levels of Bloom’s
taxonomy as per the outcome defined for the course.
Semester-End Examination:
Theory SEE will be conducted by University as per the scheduled timetable, with common question
papers for the course (duration 03 hours).
1. The question paper will have ten questions. Each question is set for 20marks.
2. There will be 2questions from each module. Each of the two questions under a module (with a
maximum of 3 sub-questions), should have a mix of topics under that module.
3. The students have to answer 5 full questions, selecting one full question from each module.
4. Marks scored shall be proportionally reduced to50 marks
