#OperatingSystemByNeso #os #OperatingSystem #OperatingSystemStructure
There are 5 types of structures for operating system:
1) Simple structure
- Every layers can access to the hardware
- Weak security
2) Monolithic structure
- All functionalities are inclued into one kernel level
- Hard to maintain, debug
3) Layered structure
- Each functionality is one layer
- One layer can only communicate directly with the layers above and below it.
4) Microkernels
- Only core functionalities are included in the kernel level
- All other functinalities moved to the system programs
- Communication between programs use passing message
5) Module
- One core kernel in the middle
- Other functinalities connected to the core kernel
- Communication between modules through the core kernel
Thanks man
What is kernel ? Can u please make me understand in simple words
@@offcourse-cv3bc It's basically like heart of the operating system .
It's is the core part of the operation system@@offcourse-cv3bc
The one program running at all times on the computer or important program which performs majority of tasks running in os is kernal

Tanks Alot! 😀
@@Redbug72it is thanks not tanks 😅
Great video! This channel has been very useful for multiple classes throughout my CS degree so far. Really makes you think about how the current way that colleges operate is clearly not the best, when we can learn the same information for free and in less time from a CZcams video.

Sir I'm crying right now because you made this content so easy to understand and explained so well. I hope you see this comment and with you well in life. THank you so much.
don't cry :)
good morning sir pls show bobs adn vagene
@@SkyV77😂😂😂🎉🎉🎉😅😅😅❤
@@SkyV77 yeaa stay happy
To the author and creator: Thank you for creating such a great set of videos! They dove-tail nicely with other resources on operating systems as the series follows the same approach or sequence of three general areas: processes, concurrency and persistance. Once again, thank you for the time and energy put into this series!
You sir are a hero, pleassssssse continue to make more videos and finish the series. Your viewers will be so so grateful.
I read a whole chapter in my textbook about this and didn't understand as well as I do now after watching this video. Thank you so much!
So moral of the story "don't read the book, watch videos and learn"
Amazinggg! One of the best video on this topic so far
Very beautifully explained!!! Thank you.
Great video, matched up with my lectures well - good visualisation too!
You are very good at OS thank you I'm now understanding it... good job
Neso Academy is doing Great Work!!
Amazing.
This tutorial elaborates some of the most important structures of operating system i.e. Simple, monolithic, micro kernel, layered and modular. However it also discusses advantages and disadvantages of each structure. It concludes modular approach as the best one as it comprises of separate modules linked with kernal.
This is definitely a well-defined lecture.
You are so good man!!! Thanks a lot!!! Please, carry on with your job and never stop!!!
Excellent sir 👍 hats off .. I read the text book 3-4 times... Still I didn't understand the concept.. but hearing this video, just for one time It was fully cleared and I was able to deliver lecture to my students eazily 👍 thank you so much for this video sir 🙏
thanks for making videos on operating system,please upload more
Looking forward to it thank you sir
Long live neso academy
Thank u soo much very nice explanation sir
Very beneficial
Jazakallahu khairan kaseera 🥰
Good Explanation. Appreciated.
Awesome explanation!
very useful thank u somuch
Great tutorial, Thanks
NESO you are the best thanks !
Thank you so much 🌸🌸
Thank you so much sir!!!!
Sir very well explained... Thank you so much
Nice explanation sir... Tq🙏
Thank you very much
Well explained 💯💯
sir what are the next subjects on your lectures
I am always following neso academy
Amazing video, Sir!! God bless you
Great work!
Make more videos sir.......😃 u r awesome
Nice explanation sir
Thank you so much sir
Excellent video
One question sir: what happens in modular approach if any of the module crashes, as each and every module is directly connected to the core kernal, then kernal also crashes, and then whole system fails. So how to deal with this type of situation?
Thank u so much.
does Modular structure have any disadvantages?
Great work👍
Videos are GREAT!!! Even for russian and ukrainian speaker. Respect!:)
God Bless you man!!
Really awesome tutorial !!
Que aula incrivel!
despacito 😁
Very well explained..thank u.😊
Very useful, thank you for spreading knowledge 👍
very well explanation and extending information is very well
Thankyou sir 😊
Thanks.
Thanks ☺️😻👍 alot!!!
Great video , Thank you Neso Academy ❤️
Thank you sir
You explain in simple words that can be understood easily
interesting ....thanks
Thankyou sir
Tnq sir 🙏🏼
Thank You so much.. this is helping review OS class i took 18years ago so easy and efficiently.. to the point..
At 8:56
Sir please make videos of software engineering
Because of your videos I think I can pass my exam😄😄 thank you 💐💐
Your content is inspired from Ekta Walia book I guess.. How very interesting 😄😁
Genial i ho trobo a més interessant.
Please put all os videos on CZcams please🙏🙏
bahut achaaa
Love you sir 😘💕
nice video
Which methodology method used to develop operating systems????
sir your videos are true gems..It is better than unacademy plus courses.
if you could have added a few examples
what is the meaning of system overhead?
What are the disadvantages of modular structure?
Can some one explain wht is this because I new to this concepts
Sir, in micro kernel device drivers,file server are present as system programs....but how system programs can be executed in user mode?
via system calls, user mode programs can call system calls in order to acquire resources from kernel
Can anyone tell me what is kernel
You missed out hybrid systems..
Really it is very helpful for my seminar sir...tq u sir....❤
Oooooo ek no
Well I can't put my finger on the differences between micro and modular kernels the way you describe it 🤔
In microkernel, the kernel only packs the important features and user programs had to do the heavy works in contrast to modular kernels the kernel is built in a modular fashion and message passing is not required here
please explain to my that expression "can't put my ffinger on"
in the simple structure.. if the application program fails, why and how would the entire system will crash? can you answer?
I guess that when an application has acces to hardware directly, and it modifies something in memory that is essential to make the OS run (which a more advanced OS structure would never allow to happen: it has security), you can get a system crash. If your app accidentally modifies a location in memory that belongs to an output pixel buffer for your screen, it may not be that bad: you would see your screen making weird colors, and other apps that acces that same buffer will get wrong color calculations at best. No crash. But if an app modifies an instruction in memory that the processor was planning to use, there's no easy prediction of what may happen. That one flawed instruction may cause a chain reaction and modify other instructions in memory, and may crash the system.
So which one is Linux?
Plzz complete the os lectures
Isn't the MS-DOS architecture considered monolithic too?
It is monolithic.
gd one
please i want this ppt can you send me
hello, the term structure of an operating system is a synonyms for the term architecture of an operating system?
Sir plz help me
In a movable head system,the time it takes to position the head at the track is known as
1 Seek time
2 rotation delay
3 access time
4 transfer time
seek time (probably)
In module operating system won't it take time to load a particular module in kernel and this will make our process slow and CPU would be idle for a long time
5:29 CPU SHIDOOLING
What about hybrid structure
Yeah was looking for that
bro...please release notes.
CPU shadooling
Linux is monolithic structure, is it correct?
Example for micro and monolithic kernel?
