Throughput
Which term refers to the amount of time a specific process needs to wait in the ready queue?
Waiting time
What does the term 'Response time' refer to in the context of process execution?
The time from request submission to first response
What is the purpose of timer interruption in process scheduling?
To enforce returning the CPU before a burst is complete
Which function is NOT performed by the Dispatcher in process scheduling?
Monitoring CPU temperature
What does 'Turnaround Time' represent in the context of process execution?
Time from submission to completion
What is a process in the context of an operating system?
A program in execution that performs specified actions
How can thread be defined within an operating system?
The unit of execution within a process
What is the primary responsibility of an operating system?
Managing all computer processes
How does an operating system start managing programs on a computer?
By loading programs into memory
What initiates the process creation in an operating system?
User interaction with a system call
What distinguishes a process from a program?
A process performs specified actions in a program
What is the main task of CPU scheduling?
Ensuring that whenever the CPU is idle, it selects a process from the ready queue for execution
What happens to a process once it has started executing?
It can be blocked or go into a waiting queue
What is Preemptive Scheduling?
Assigning tasks based on their priorities and allowing higher priority tasks to interrupt lower priority ones
What does the operating system do after the execution of a process?
Terminates the Process Control Block (PCB)
Who selects a process for execution from the ready queue?
CPU scheduler
In which scheduling method do tasks get interrupted based on their priorities?
Preemptive Scheduling
What is the main purpose of a dispatcher in a computer system?
To provide control of the CPU to the process
In the First Come First Serve scheduling method, which process gets CPU allocation first?
The process that requests the CPU first
What principle does Round Robin scheduling operate on?
Equal share of CPU time for each process in turn
What is the key criterion for selecting the next task in Shortest Job First scheduling?
Shortest execution time
What does the multilevel queue scheduling method do?
Separates ready queue into various separate queues based on properties
How does the Shortest Remaining Time algorithm allocate processes?
Based on the process closest to completion
What is the full form of FCFS in process scheduling algorithms?
First Come First Serve
What is the main characteristic of Round Robin Scheduling?
It ensures an equal share of CPU time to each process in a circular queue.
What does SJF stand for in process scheduling algorithms?
Shortest Job First
How does Priority Scheduling work in process scheduling?
Tasks are executed based on their priority level.
What is another name for Shortest Remaining Time (SRT) scheduling?
(SJF) Preemptive Scheduling
Which scheduling algorithm prevents newer processes from delaying the completion of older ones?
(SJF) Preemptive Scheduling
