Your videos are just amazingggg. You are our college CSE saviour. Please upload next videos also.

[monetka]

Neso, you are my rescuer!!! I am studying Operational Cyber security and don't have any background in IT. You are a Master in explanations!!! Bravo!!!

[Aimanmughal-jb]

Explain in a simple way and clear all the concepts❤❤you are the Best Teacher

[omop]

This is free and my college fees is 8 lakhs, we need to get rid of institutionalising education

[youssefguerboub]

Thank you very much, she explains in a great and simple way and starts with all the basics, I have a question regarding idle process why do we need it and why is it taking the most percentage of CPU, in other way why do we need to keep the processor busy all the time.

Thank You! So, the criterias for judging the efficiency of some particular scheduling algorithm are: CPU utilization, Throughput, Turn around time, waiting time, response time. by CPU utilization it means how much the CPU is utilized, it should not be left idle, throughput means number of processes executed per unit of time, turn around time means to execute a particular process from the time it is loaded into the memory to the time it gets complete, waiting time says the time processes need to wait. Lastly, response time is the time when the first response of the process is produced. There is need to understand the difference between turn around and response time.. Turn around time may get delayed due to the efficiency of output device. Therefore it may not be an appropriate factor to judge the quality of an algorithm.

This is the lecturer that is supposed to be paid. Not in institutions where they don't teach like this. Can I find a way to support this channel

[saddamahmad]

thank you very much sir for this video

[kizzasam]

your explanation is amazing, am a student at muni university in Uganda

[random_clicks]

Never seen this type of teaching experience

[prernagarg]

Thank you so much Sir, my doubt are clear.

[RadhikaGarg-evfr]

You areewe bestt..your video is best and understandable..thanks soooo

1) CPU utilization
2) Throughput
- Number of processes to be executed in a time unit
3) Turnaround time
- Time between subscription of a process and its completion
4) Waiting time
- Time that a process needs to wait in the ready queue
5) Response time
- Time between process subscription to execution and first response of the program

Plz guys support this channel by contributing small amount through donation as this is the only channel which provide good content and remember good things never come in free so request u all plz donate so that the aim of this channel to provide free education with good content goes on . I donate plz guys start your good initiative

[khSoraya]

u said throughput is the number of processes that are completed per time unit .. how can we calculate it since we never know when a process is gonna end !!

[akasha.sgowda]

Can you please share the ppt of the lectures .So it can used for revision

[subhamghosh]

Please provide this notes...It will be really helpful

[alihogilbert]

can the CPU utilization reach at 100percent

[ankitraj]

Sir🙏
What criteria affect the cpu scheduler's performance ??

I still did not understand
How do you define "response time"
in term of "process state".
Because based on your video regarding process state, after running state, the process goes to waiting state before I/O give response.
In this video regarding response time, if the system is too quick, too responsive, or too interactive for example like playing video game. So, you said that the response time is measured from new state to the first response provided by the
I/o. Meaning not necessarily the time taken needed for the I/o to be displayed to the user.
So in term of process state, how do you define response time?
Is it from new state to in between waiting state and event completion?
I am assuming that in between the waiting state and event completion state, there is the state where the I/o give response to the process, then goes back to ready state, then to running state then to another I/o device as to show the user about the
Effect of the first input. so, response time is the measure from new state to the first I/o response not the
I/o response that are shown to the user.
For example, if I play a video game on ps4, I press a button, when the
I/o give response to the process but
still the process does not gain access to cpu yet meaning it is just reaching ready state..
So that is the time we measure response time? Not necessarily the time for the effect of the I/o to be shown on the monitor, like for example where my player in the game is going.
