In this session, we will look at the following: 1. Interprocess communication ( IPC ) 2. Introduction to threads 3. Difference between threads and process 4. Multiprocessing vs multithreading 5. Multithreading challenges I will also be showing real examples of these on my linux based operating system. #operatingsystem #processmanagement #interviews #threads #interprocess #communication #multithreading #multiprocessing #computerscience What is an operating system? Functions of an operating system System calls in operating system Interrupts in operating system Difference between program and process Process control block Process states in operating system Scheduling queues in operating system Schedulers in operating system - long-term, short-term and medium-term Context switch in operating system Dispatcher in operating system Process creation using fork system call exec(), wait() and exit() system calls Examples of fork command Zombie and orphan process in operating system Interprocess communication in operating system What is a thread in operating system Difference between a process and a thread When to use process vs threads Multithreading models in operating system What is race condition in operating system with examples? What is critical section in operating system with examples? What is critical section problem and requirements for a solution to satisfy it? Peterson's solution for critical section problem - a software based solution. Drawbacks of Peterson's solution exaplained in details Test and set lock solution for critical section problem Critical section problem solution using swap instruction Semaphore and mutex in operating system Spin lock vs mutex vs binary semaphore vs counting semaphore Producer consumer solution using mutex and semaphore Reader writer solution using mutex and semaphore CPU Bound process vs IO Bound process Preemptive vs nonpreemptive scheduling process scheduling in operating system fcfs scheduling algorithm in os fcfs scheduling algorithm in operating system fcfs scheduling sjf scheduling algorithm in os sjf scheduling algorithm in operating system sjf scheduling sjtf scheduling algorithm in os sjtf scheduling algorithm in operating system sjtf scheduling priority scheduling algorithm in os priority scheduling algorithm in operating system priority scheduling with io burst round robin scheduling algorithm in os round robin scheduling algorithm in operating system round robin scheduling with io burst LRU page replacement algorithm in operating system Optimal page replacement algorithm in operating system FIFO page replacement algorithm in operating system Page replacement technique in operating system TLB cache in operating system Paging in operating system Demand paging in operating system Paging and segmentation in operating system Swapping in operating system Logical memory and physical memory in operating system Memory management in operating system Virtual memory in operating system Page replacements algorithms in operating system Contiguous memory allocation in operating system Contiguous and noncontiguous memory allocation
