What is First-Come-First-Served (FCFS) Scheduling?
First-Come-First-Served (FCFS) is a non-preemptive CPU scheduling algorithm that runs processes strictly in the order they arrive in the ready queue, giving ea…
What is Shortest-Job-First (SJF) Scheduling?
Shortest-Job-First (SJF) is a scheduling algorithm that always dispatches the ready process with the smallest total CPU burst time next, which provably minimiz…
What is Shortest-Remaining-Time-First (SRTF) Scheduling?
Shortest-Remaining-Time-First (SRTF) is the preemptive version of Shortest-Job-First: whenever a new process arrives, the scheduler compares its burst time to…
What is Priority Scheduling?
Priority scheduling dispatches the ready process with the highest priority value next, rather than by arrival order or burst time, and can be implemented as ei…
What is Multilevel Queue Scheduling?
Multilevel queue scheduling partitions the ready queue into several separate queues by process type — such as system, interactive, and batch — each with its ow…
What is Aging in CPU Scheduling?
Aging is a scheduling technique where the OS gradually increases the priority of a task the longer it waits in the ready queue, which guarantees that even a lo…
How to Design an Elevator System?
An elevator system is designed around a central dispatcher that models each car’s state (position, direction, queued stops) and assigns hall calls to the car t…
