This course introduces students of 5-year Integrated M. Tech (CS) students to operating systems, their functions and design. Emphasis is on learning concepts related to general operating systems while using Linux as a case study.
An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware.

Rules
Students are expected strictly to follow the rules and grading guidelines listed here. Some of these are university requirements while the others are for this class.
- Students will be evaluated continuously over the semester.
- Students must take part actively in classroom activities such as quizzes, discussions, etc.
- Internal evaluation for 40% is based on:
- Assignments (2): 2 X 10 = 20 Marks
- Term reports (2): 2 X 10 = 20 Marks
- Minor exam (1): 1 X 20 = 20 Marks
- External evaluation for 60% is based on end-semester exam
- Cheating will not be tolerated. The onus on proving their innocence lies on the student.
- Meet the instructor as soon as possible in case of any difficulties. Nothing can be done at the last minute.
Lab Sessions
- Lab 1: Linux OS (25 July 2019)
- Lab 2: Process Management (01 August 2019)
- Lab 3: Signals (08 August 2019)
- Lab 4: Pipes (22 August 2019)
- Lab 5: Memory Allocation (5 September 2019)
- Lab 6: Memory Management (19 September 2019)
- Lab 7: Memory Management (contd) (3 October 2019)
- Lab 8: Page Replacement Algorithms (17 October 2019)
- Lab 9: Study on Page Faults (24 October 2019)
- Lab 10: Writing a Device Driver (07 November 2019)
In this lab, use this link to write a "led_panel" driver.
Then, attach the driver you wrote to a device called "panel" (/dev/panel). You can use this virtual LED panel (written in Python 3 to access /dev/panel) to have some fun with the driver! The LED panel needs tkinter module to work properly.
