Requirements
No previous knowledge about operating systems needed. Everything you need to know about the topics will be covered.
Description
Ace operating systems (OS) principles, system calls, OS protection, processes, CPU scheduling, CPU scheduling algorithms, interprocess communication questions in competitive exams, job interviews, and OS course exams.
Do you know: How OS protects itself from the user programs How does OS protect user programs from each other Why can user programs not directly access I/O devices Why do programmers prefer to use APIs over system calls in programs How is the CPU shared between so many active processes How does executing processes create new child processes How do cooperating processes communicate Learn the explanations to these and many more intriguing questions in this course!
Specifically, the course will cover the following in detail.
