What is CPU Scheduling?

CPU scheduling is the OS mechanism that decides which ready process or thread gets to run on the CPU next, aiming to balance throughput, fairness, and responsi…

Preemptive vs Non-Preemptive Scheduling

Preemptive scheduling lets the OS forcibly suspend a running process to give the CPU to another, while non-preemptive scheduling requires the running process t…

What Is Round Robin Scheduling?

Round robin scheduling is a preemptive CPU scheduling algorithm that gives every process a fixed time slice, called a quantum, in a cyclic order, so no single…

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…

Round Robin vs Priority Scheduling: What is the Difference?

Round Robin gives every ready process an equal, fixed-size time slice in strict rotation regardless of importance, prioritizing fairness and responsiveness, wh…

Waiting Time vs Response Time in Scheduling

Waiting time is the total time a process spends sitting in the ready queue without running, while response time is the time from when a process arrives until i…

What is a Load Balancer Algorithm?

A load balancer algorithm is the rule a load balancer uses to decide which backend server receives each incoming request — common examples include round robin,…

Round Robin vs Least Connections Load Balancing

Round robin distributes requests to backend servers in a fixed rotating order regardless of current load, while least connections sends each new request to whi…

What is Load Balancing?

Load balancing is the practice of distributing incoming network traffic across multiple backend servers so no single server is overwhelmed, improving availabil…
