Well elaborated.
This lecture explains two important features of operating system i.e multiprogramming and multitasking.
In multiprogramming, multiple jobs are being executes by the processor simultaneously. CPU time is shared among different jobs. Whereas in multitasking, multiple users are being entertainment by a common system. It means time of a single system is shared among different users.
An important term "process" is highlighted by the tutorial. It says, a process is programming that is loaded in main memory and is executing.
Hi, there's just one question that's been bugging me: what exactly is user in this context? The program that is running or the actual human using the device?
@@tuantranluuquoc2910 In the context of computing, the term "user" generally refers to the human operator who is interacting with the device or running the program. For example, when you log into your computer, you are the user of that device. When you open a program and interact with it, you are the user of that program. However, in some cases, the term "user" may also refer to a program or process that is running on behalf of a human user. For example, when you open a web browser and navigate to a website, the browser is acting as a user agent on your behalf.
The lectures are great! Being from a ece background, I was having a hard time to grasp the concepts of OS but watching these lectures made it simple. Thank You!
Acha beta 😂
Thanks!
1. Multiprogramming
2. Multitasking (time sharing)
3. CPU scheduling algorithm
4. Process is a program loaded into main memory
Sir, today I saw a Book "Operating System Concepts" by Peter B Galvin. The concepts(including examples) are very similar!
They are teaching us using Operating System Concepts (9th Ed) - Gagne, Silberschatz, and Galvin this book. They really doing a great job :)
@@Sauravgpt34 Right ..In Book we need to understand..But here they explain the concepts very clear and systematically.
You can also see the books used by them...Link in *DESCRIPTION*
Almost everything is the same..the pattern as well...
Yeah
Am glade to these lectures since explanations for questions are well elaborated
bro, you literally following my curriculum, wtf is that? Thank you bro, much loveeeeeeeeeeeeeeeeeeeeeeeeeeeee!
In multiprogramming, the switching between tasks is done when the execution of a current task is suspended, which happens when the current process gets occupied for some reason. In multitasking, a fixed amount of time is provided for the execution of each task. And only after the expiry of that specified time is the switching of tasks.
Thank you Soo Much for referring OS from standard textbook (abraham Silberschatz)
GOD bless u
Sir plz upload videos as fast as possible...our exams r very close to start
this OS playlist is the best so far.
Please do it fast. You are the best👌
Your explanation was so nice ....please make videos on python language
sir ur explanation is so...nice.....we want tutorial on data strutures in python ...plz
you explained the concept very well...
Well explained sir ,I am enjoying the journey of operating system with you
Super teaching❤❤❤
Very nice explanation. God Bless You... I have my paper on 7th...
@@nesoacademy thanks a lot. My wishes are always with this Channel..
and thanks again your lectures are so helpful
Very clear explanation and worth of it!! God Bless you sir.
Thank you!! You are the best .
thnx a lot! ❤❤
How do we share the system between many users, and what's max users limit to use system
When one uses the system, and other using also.. how the arrow responds to it
bro watch the next video of this tutorial
Thank you very much
Nice video useful tq sir...
So nice
🇹🇿🇹🇿🇹🇿🇹🇿 Best teacher ever
Is it enough for gate examination
In multitasking hw multiple users can use same computer at the same time? I don't understand
Depends on the limitations of your CPU and memory
Not multiple users but a single user performing multiple tasks at the same time on the same computer.
Just take an example of Wifi and the main computer as a server, I think you'll understand the concept then.
Of how so many people are using the same service and think that the service is provided only to them as the switching between the users is so fast.
Thank You 🙏🏻
best lectures
nice vid .sir....upload more vid ..and let's have a fun with os
Thankyou sir
Plz upload soon
Plz upload videos on system.design , btw awesome content 👍
very interesting lecture
thanks alot sir
How can multiple users use the same computer or OS at the same time? Only one can use a laptop or computer at once, right?
I don't quiet understand the end with the four users. Is that a hypothetical scenerio or a in a time-shared system there are always multiple users?
Please share lectures handouts plz...
please add all whole operating system course.plzz
Kindly provide link to your previous videos. I want to watch your videos from the very begining

Sir apne operating system operation topic pr video nhi banaya?
PROCESS -> A program loaded into memory and executing
can't find previous videos
where can i find the lecture notes ?
🔥
Sir please more videos on operating system... Whole syllabus
Even me
level boss
when is the next lecture coming
Is multiprograming and multitasking use multi cpu?
Sir plz upload more and fast on os🙏🙏🙏
Are you following entire gate syllabus for these videos.
this year i also see that
was watching this and my pc ran into a problem and turned off and couldn't boot after that looks like I need to learn fast
cpu execute jobs by switching among them means
There is a time period allocated for each job by the cpu(that is what time sharing slot means) and after that time period the cpu switches to the next program to be executed
Thanks but plz sir do it fast for us
We really need these videos
Can I ask you something 🙏
What I want to know is is it possible to learn os without computer science knowledge?
Sir,
Are I/O devices not use CPU for their process?
As explained in video ,when Job1 was using CPU and Job1 wants to use other resources lets say I/O device.
then is it not a dead-lock?. Because already CPU is being used by Job1. Then, how I/O will use same CPU in single programming system?
Correct me if I am wrong
Thank you
Users here are programs running not actual users I think
please sir try to upload a little faster
You can talk much louder
you present the info too dry, no practical examples connected with concrete programming language.
Thanks a lot
Thankyou Sir
Thank you very much
