This is a course of Operating Systems. As this course is focused towards NTA UGC-NET exam so I will give you an overview and strategies to handle this subject.

Prepare for UGC NET 2019 by watching our free online lessons covering UGC Net syllabus and also helping you solve Previous year question papers. Pursue your dream of JRF.

NTA-UGC-NET & SET Exams

English

NTA UGC NET- Operating System

Basics of Operating Systems

System Software & Operating Syst.

Computer Science & Application

NET Exams

Ace the toughest competitive and government exams in India 

Test Preparation

An overview of OS telling you what comes ahead in the journey so you the learner can buckle up and get most from this lecture.

Overview of Operating Systems

This lecture is basic of Operating system where we talk about the type of OS. We even sees the pros and cons of each OS with some real life examples

Basics of Operating System

This is the basic past of OS where we will learn about multitasking, multithreading, multiprocessing and multiprogramming.
Watch the lecture to know more about it.
Don't forget to rate the lecture and enroll in my class for more updates.
Keep learning

NTA UGC NET Basics of OS- 2

In this lecture we will learn about the basic terms like RAM ROM, what happen when we start our system? How the BIOS works and what is UFEI.
These are all basics if you very well versed on it you can move to the process management part.
If you like my teaching kindly enroll to my class and help me improving the lectures so we all can learn freely

NTA UGC NET Basics of OS-3

In this lecture we will learn interesting things about process management. This is a introductory class dealing with the definition and different processes, process states, scheduler.
Get more interesting insight about the process management keeping watching my lectures. Enroll to my class so you can get maximum benefit in your preparation.
I would request students to rate and review the lectures

NTA UGC NET Process management -1

Here we are learning about important points in process scheduler how the process are created, when and how. Later we will see the process control block which shows how physically the processes are maintained.
This is an important topic for UGC NET and even to understand the basics of process management. Kindly read the OS Galvin book unit 1 and come back again to my videos your concept will get crystal clear.

Let's learn it!

Process Scheduler and Process Control Block

In this lecture we are studying about the system calls and threads.
Threads are important in perspective of exams and understanding why a multiprocessor system must have multi-threading. We will also learn the types and models of threads with its benefits.
Kindly study the points and take notes while pausing the videos in this way you can understand better. And study the Galvin book to get thorough in the topic

System calls and Threads

We are going to study the previous year question I have compiled from PYQP of NTA UGC NET 2012-17 which are mostly the part we have studied in the previous lectures.
Kindly go through the previous lectures make the notes and come back and give this test. Kindly post your answer below before checking the answer key.
Lets learn it!

PYQ NTA UGC NET 2012-17

A major topic of process management is CPU SCHEDULING. We will learn about FCFS- first come first serve in this lessons.
Lets learn it!

CPU SCHEDULING - FCFS

In this lecture we will see about the two shortest job algorithms which is both preemptive and non preemptive in nature.
We will study about shortest job first and shortest remaining time first algorithm.
Let's learn it!

CPU SCHEDULING - SJF & SRTF

In this lecture we will see to calculate the priority scheduling, infamous round robin algorithms and also the highest response ratio next scheduling algorithms.
Kindly enroll and rate my lectures.
Let's learn it

CPU SCHEDULING - Interactive algorithms

In this lecture I am going to teach you multilevel queue and multilevel feedback scheduling algorithms.
Let's learn it!

CPU SCHEDULING - multi level queue and multilevel feedback queue scheduling

It is always important to study the PYQ before attempting any other exams.
Let's study the PYQ for CPU SCHEDULING.

PYQ NTA UGC NET (2012-17)

This is an introduction of process synchronization for better understanding the concept behind IPC, shared memory, classical synchronization etc.
Let's learn it!
I request you guys to view and share my lectures and enroll in my class ASAP

Process Synchronization 1

Please enroll and watch my lectures I am desperate YES! Anyways this is the synchronization if you guys don't watch my lectures and if I am not reaching to you in a wide range how the channel will grow? How you will get educated?
So we need to sync here you fella watch my lectures I will upload new lectures as simple as that. To learn more of the synchronization go to my lectures go go....
Any doubt ping me!!!!

Process Synchronization -2

Process Synchronization -3

So, semaphore and monitor is waiting for you signal the button of play to start the lectures for whom you are waiting go learn and learn it fast!

Process Synchronization -4

Alright deadlock! So don't put yourself in deadlock by procrastinating your task to perform in FB and YouTube. Come to Unacademy and study deadlock so you can avoid a situation of resource allocation without making any kind of mess.
Let's learn it

Deadlock-1

To deadlock situation you need methods to handle this. In this video we will learn about two methods of deadlock avoidance and prevention. Rest method in another video.
So let's learn it

Deadlock - 2

Bankers algorithms is very important in perspective of NTA NET exam every tea 1-2 question ask from this topic. It is a very mathematical problem I request all the fella to sit with a pen and paper and solve the problem along with me.
Please solve the given assignments problem without a fail and post me the answer below

Deadlock-3

Now it is important to detect the vicious deadlock and schemes to recover from it.
In this lecture we will even learn about detection algorithms.
Let's learn it!

Deadlock-4

This is an introduction to memory management where you can learn about absolute address, relocatable address, address binding, dynamic linking and loading

NTA NET Memory Management-1

We will learn about best fit, first fit and next fit algorithms with previous year GATE question

NTA NET Memory Management -2

In this lecture I will teach you about internal and external fragmentation for better understanding

NTA NET Memory Management -3

This is an introduction to paging and how the logical address is looking for physical address in physical memory.

NTA NET Memory Management -4

Paging problem is very important in perspective of examination. Please use paper and pen to study this lecture

NTA NET Memory Management -5

In this lecture we will study more about the TLB, inverted page table and multilevel paging

NTA NET Memory Management -6

This is last lecture on memory management we will learn about the buddy system and need of memory management system

NTA NET Memory Management -7

In this lecture we will see the introduction of virtual memory and some over all information about the demand paging

NTA NET Virtual Memory -1

This lecture is about thrashing, swapping done in virtual memory

NTA NET Virtual Memory -2

In this lecture we will study about the page replacement algorithms like FIFO, LRU and Optimal algorithms

NTA NET Virtual Memory -3

In this lecture we will study about the unix I node problem which is very important in perspective of Net exam

NTA NET File System-1

In this file system we will study about the NTFS mad other free space management techniques

NTA NET File System -2

Disk scheduling is major deal and i will help you to visualize the hard disk structure

NTA NET File System -3

In this lecture we will study about hard disk addressing and also the RAID structure let's study it
