Operating System Fundamentals
Operating System Fundamentals. Instructor: Prof. Santanu Chattopadhyay, Department of Computer Science and Engineering, IIT Kharagpur. Operating System is a computer software that manages the hardware components. It acts as an intermediary between the users and the hardware. It is responsible for managing the system resources and providing a smooth working environment for the users. As a subject, it is an amalgamation of the fields like computer architecture, algorithms, data structure and so on. A course on fundamentals of operating systems is essential to equip the students for taking up the challenges in understanding and designing of computer systems. This course will address all the fundamental points, starting from the foundations to the architectural issues to correlation with existing commercial operating systems.
