What is Inter Process Communication?
Inter Process Communication (IPC), a key topic for managing and synchronizing multiple processes; includes diagrams and explanations on methods like message passing and shared memory, making it useful for understanding how processes can communicate and work together within an Operating Systems.
Difference between Concurrency and Parallelism
Differentiates between concurrency (multiple tasks starting and stopping) and parallelism (tasks running simultaneously), helps to studying operating system efficiency and performance management.
Process Synchronization
In-depth overview of process synchronization, cover both fundamental and detailed aspects.
Deadlock, Livelock and Starvation
Three scenarios where a process may face issues while waiting for resources: deadlock, livelock, and starvation; explain which processes fail to proceed and how each scenario differs.
