What are scheduling algorithms and how do they work?

Scheduling algorithms are methods used to allocate resources, like CPU time, to various tasks in computing. They determine the order in which tasks are executed.

Can you explain the different types of scheduling algorithms?

Sure! There are several types, including First-Come, First-Served (FCFS), Shortest Job Next (SJN), and Round Robin. Each has its own advantages and use cases.

What is the difference between preemptive and non-preemptive scheduling?

Preemptive scheduling allows a task to be interrupted and resumed later, while non-preemptive scheduling runs a task to completion before moving to the next one.

Which scheduling algorithm is the most efficient?

Efficiency can vary based on the scenario. For example, Round Robin is great for time-sharing systems, while SJN is optimal for minimizing wait time.

How do real-time scheduling algorithms differ from general ones?

Real-time scheduling algorithms prioritize tasks based on deadlines, ensuring critical tasks are completed on time, unlike general algorithms that may not consider timing.
