Congratulations Varun sir, I just watched that this video got 1M+ views, really thankful to you for helping me since 2nd year till 4th year of my college.
Summary notes: Introduction to operating system and its functionalities. Operating system acts as an interface between user and hardware. Without it, accessing hardware would be complex. [00:00] Introduction to Operating System and its functionalities - Operating system is a system software that works as an interface between user and hardware. - Without an operating system, the user would have to write a program for each hardware device to access it. [02:28] Operating systems provide convenience to users - Writing individual programs for each device or task is complex - Operating systems act as an interface between users and hardware [04:53] Operating systems need high convenience and throughput - Windows acquired 95% market share due to convenience - Linux gaining popularity due to high throughput [07:18] Operating systems manage resources and processes - Resource management involves allocating hardware to users and managing system load - Process management involves managing the processes running on the system [09:53] Operating system manages CPU scheduling, storage, and memory - CPU scheduling algorithms are used to execute multiple processes efficiently - Storage management involves managing data storage in secondary devices like hard disk - Memory management deals with managing RAM [12:23] Operating systems manage RAM and swapping to execute processes efficiently. - RAM is limited and processes are executed first in RAM. - Swapping is the process of taking out a completed process from RAM and bringing in the next one. [14:27] Operating system provides security and privacy - Uses Kerberos security protocol to keep passwords secure - Provides security between processes to prevent interference or data change [16:54] Operating system works through system calls - System calls like read, open, write are used to access hardware - Applications like print command invoke system calls to interact with hardware

Gate smashers is one of the favourite channel of almost all computer science students because quality content is presented to students in simple and easiest way & much much better than college and university professors in less time. This channel has grown faster because almost every student gives his/her blessings to Varun Sir. Shine more & keep growing because you have always been a saviour for us.
Nope, I'm not watching before the exams. Recently I've finished my semester and now I have it in the syllabus. Why I'm watching this, is because last time while giving an exam i was in regret and was thinking of studying little by little for at least 20 minutes. Let's see my consistency.
Your teaching method is so much practical & effective specially understandable 🔥🔥🙌TQ so much for providing this to us especially freely 🙏🙏with amazing teaching method
I for this semester, referred your videos (3rd yr) and god , literally sir, you made it easy. While being worried about knowing nothing and watching your videos for few hrs the night before exam and reviewing it again mrng and say what? I learned the while syllabus without even knowing that I actually did it. Thank you so much sir. Wish I had people like you to teach us at college, ( due to COVID there isn't one good faculty to teach, the leftover staff just learnt at the moment just to teach some, no hate for them but still , teaching like you would have made our lives more better) Thank you!
I completed whole playlist today for my campus placements. It took me 1 week to complete it. Thankyou so much sir for helping us with your lovely content ✌😊
can you tell me is it sufficient for placement preparation in os...i am in 4th semister..i think you are my senior ,if it is possible can you give me some tips like on which subject i have to focus more rather than other subject...i waste many time due to online classes , exam but due to offline classes getting started i want to do the productive work and want to know important subject for placement as other subject i only do for passing out my semester😂😂😂😂..
immense gratitude for you and your team Varun Sir. You taught and explained me the whole syllabus in 2 days easily where my College was unable to teach even one topic efficiently. You are one of the most important part of my career Varun sir. Love from bottom of my heart❤
Concept of Security and privacy can be understand by an example:- Just Suppose you are playing PUBG if their is no such security. One can access your resources and write something as a result your health decreases from 💯 to 20%.😅😅
On normal 1.0x the video feels like it is already slowed and on 1.5x it feels like the normal video playing 💀, anyways thanks for the whole operating system playlist it was really useful
