kon teacher bana diya yr bahot boring h

bro this man dont know how to speak ?? and he call himself professor smd

boring

Boring explanation

Questions are different, video lecturs are different, solutions are wrong. Teaching is not crime but wrong teaching is crime. You must note down.

Worst course:- Lack of knowledge because of wrong information available in NPTEL video lectures and assignment.

Worst NPTEL

- [00:00]🖥 Introduction to Operating Systems Layers - Computer systems are structured in layers from transistors to hardware to applications. - The bottom layer consists of transistors combined to form logical gates like AND, OR, XOR. - Hardware includes memory cells, flip flops, registers, and various units like RAM, instruction fetch unit. - [02:22] 💻 The Role of Operating Systems - Operating systems manage applications and resources in a computer system. - They provide hardware abstraction, making it easier for software applications to utilize hardware. - Resource management by the OS deals with the limited hardware resources in a computer. - [03:40]🧠 Program Execution and Display Process - Explains how a program written in C language displays text on the monitor. - Details the process of transferring the text from memory to the monitor via the graphics card. - Highlights the complexity that would arise for programmers without the abstraction provided by the OS. - [07:36] ⚡ Benefits of OS Abstraction - Operating systems abstract hardware details, making programming easier. - Applications can reuse OS functionalities, enhancing efficiency. - OS enables portability, allowing programs to run on different hardware without modifications. - [10:19] 💾 OS as a Resource Manager - Operating systems manage hardware resources for multiple applications running concurrently. - They supervise resource allocation for components like CPU, memory, network, and storage devices. - OS ensures efficient sharing of limited resources while protecting applications and their data. - [16:43] 🔐 Security and Classification of Operating Systems - Operating systems are essential for all smart devices to function. - Classification includes embedded OS, mobile OS, real-time OS, secure OS, and those for servers and desktops. - Each type of OS is designed with specific applications and requirements in mind.kzbin.infogaming/emoji/7ff574f2/emoji_u26a1.png

Good lecture...now a days these lectures are very underrated.

Excellent

Baki sab to theek hai par apni seeti ki avaaz kam karo

How do we know that the num[i]=Max(... code line is atomic or non atomic even it's not mentioned in the question having this code

Gracias sr con un gato en la cabeza..

the context switches in this (35:33) example should be 5? what am i doing wrong?

Turbo mode is turned on

He is a living robot.

Why don't they eat with just one fork? Do they think forks have separation anxiety?

xv6 lessgo

4:52 the cs register value should be ox000f if we want to right shift by 4 ?

@16:59

Information lecture ❤

Thank you Sir 🙂

Sir U r d best one who explains this topic.thanks

Thank you for the clear explanation!!!😃

Thank you , for the wonderful sessions, numericals would be greatly appreciated if included

Dear Sir, Your videos are very much interesting and informative. Please share the presentation slides for us which could be used for studying

32:43 context switch should be 6 as it changes total of 6

Is this good for gate exam

Hi Sir, At 6:00 minutes in x86 address translation block diagram Paging unit takes linear adress as input yo get the physical address of the main memory. Is linear address is not the actual physical address of the physical memory? Which is been calculated in logical adress to linear adress slide.

i didn't know indians can explain things that well, very good explanation

great video and explaination, thank you!

sir samajh me nhi aya mujhe 🥲🥲🥲😢 but accha tha lecture

Is the page table is ~4 MB because each entry contains the address to the start of a page frame, which is 32 bits, i.e., 4 B, and hence, the page table = 2^20*4 B = 4 MB? (It is roughly 4 MB because there are a few additional bits for state, permissions?) And is the RAM 4 GB because we are assuming each memory location to be 1 B, and there are 2^32 such memory locations?

One of the best explanation Thank u sir

How is it that all processes have access to num ...don't that defeat the purpose of distributed algorithm?

Great Explanation

This video series deserves so much more attention than it currently has!

It looks like Bakery algorithm should work for n ≥ 2, but there are simpler ways for mutual exclusion for n = 2, hence the video mentions n > 2.

At around 15:18, if any process dies after setting choosing[i] = True, it will block all other processes from entering the critical section, isn't this a problem?

Thank you sir
