The Operating System


Do you know what the operating system is? Do not even know, there is nothing to panic, we will answer it and it will be answered with some other questions. As we know we are a human being and a human has a heart. In such a way, do you know how the heart works, perhaps it will not even know. What I mean to say is that as we have a heart to humans, computers also have it, and it is called Computer Operating System (OS) in the technical language.

Whenever you use a mobile or a computer, we keep talking about Android, Windows, Mac, Linux etc. So all these names are one of an operating system. If ever talk about Android KitKat and Android Oreo, or Windows, then someone speaks to them about Windows 10, Windows 7, Windows 8, Windows XP etc. Likewise happens in Mac OS. But everyone has a lot of knowledge about them all, but nobody knows what the computer's heart means to the work of this OS. In a small sense, you would like to give people that an Operating System is a type of interface and between the user and the hardware. Well, how many types are these, where are they used, what are the main tasks of them, if you want to know more then what is this article operating system? Must have read the whole. So let's begin without delay and know about the operating system.

What is the operating system?
The Operating System is also called System Software. It is sometimes called the OS with a small name. This is the heart of the computer. Operating System is a System Software, which means the user works like Interface between you and Computer Hardware.
I explain directly this sentence, whenever you run a computer, this OS gives you the means to use a computer. As you listen to the song, let's double click on the word document, sit down with four windows, write something in the keyboard, and save some files in the computer, then you can never do this without an operating system.
So this OS is a software that lets you run your computer. So whenever you buy a new computer, first of all you have to load Window7 or Windows10 and then you take the computer to your home. Otherwise, without an Operating System, you can not even turn on your computer.

There is also a question that why it called System Software. If you want to run User Software as Application Software in Computer, then they can never run without OS. This helps to make good use of OS Computer Hardware. The operating system primarily works like something takes input from Keyboard, Processes Instruction, and sends Output to Computer Screen.
You see this operating system only when you turn on the computer and when you turn off the computer. You need to have a program or big software in order to run these games, such as Game, MS Word, Adobe Reader, VLC Media Player, Photoshop and all other software computers, which we call Operating System. The name of the OS used in mobile is Android, which everyone knows about. You may have come to know what is the operating system, so let's know about some of its work.


Function Of Operating System
By the way, a lot of works are done, but first of all when you turn on the computer, the operating system first loads the main memory in the mean RAM and then allocate it to the user software from the cone angle. Lower OS
Different things have been given, know about them and in detail.
  1. Memory Management
  2. Processor management (Process Scheduling)
  3. Device Management
  4. File Management
  5. Security
  6. Viewing System Performance
  7. Reporting Error
  8. Making a Difference Between Software and User
Memory Management
Memory Management means managing primary and secondary memory. Main memory means RAM is a very big array of bytes. Meaning there are a lot of small hacks where we can keep some data. Where is the address of every single hack. Main Memory is the fastest memory to use CPU Direct. Since all the CPU programs run, they are all in main memory. Operating system does all this work.
  • The cornerstone of main memory will be used, which one will not be, how much will it be, how much will not be.
  • In multiprocessing the OS decides which process will be given memory and to what extent it will be given.
  • When Process Requires Memory, then it gives Memory OS to it (Process means a Task or a small task that is inside the Computer)
  • When Process completes its work, OS takes back its memory.
Processor Management (Process Scheduling)
When talking about multi programming environment, OS decides which process will get a processor and who will not get it and how long it will take. This process is called Process Scheduling. Operating system does all this work
  • The operating system also sees that the processor is empty or something is working, or is free and the process has finished its work or not. If you want, you can see how much work is going on in the Task Manager and not how many. The program which has to do all this work is named Traffic Controller.
  • The CPU does allocate to the process.
  • When the process of a process is finished, then he takes the processor into the other end, and then releases the processor when there is no work.
Device Management
You have to use a driver in the computer, you will know that such as Sound Driver, Bluetooth Driver, Graphics Driver, WiFi Driver, but they help in running different Input / Output Device, but these Drivers OS runs. So let's see what else this OS does.
  • Tracks all Computer Devices and the name of the program that this Task does is I / O Controller.
  • Like Devices need different tasks to do some task, OS also does the task of allocate. Take an example that a process is to do some task like video play, print, then both of these Task Output device Monitor will be done with the help of printer. So when these two devices have to give Process this OS works.
  • When the process is finished, then it deallocate the device back.
File Management


Many directories are placed in a file by organizing it. Because we can easily find data. So let's know what OS is in File Management.
  • Organizes Information, Location and Status. It all sees the file system.
  • Who will get a console resource.
  • Resource de-allocation is to be done.
When you turn on your computer, you ask that password, this means that the OS prevents your system from unauthenticated access. This keeps your computer safe. And you can not open some programs without password.

Viewing System Performance
It looks at the performance of the computer and improves the system. How much time does OS take to deliver a service, it keeps records.

Reporting Error
If there are so many errors in the system, then they detect and recover the OS.

Making a Difference Between Software and Usher
  • Assigns Task to Compiler, Interpreter and Sembler Connects the different software with the user, so that the user uses the software properly.
  • Provides communication between user and system.
  • Store is in the operating system BIOS. The rest of the application is also user-friendly.
Characteristics Of Operating System
  • An operating system is a collection of many programs, which runs the second program.
  • It controls all the Input / Output Device.
  • Operating system is the responsibility of running all application software.
  • Process scheduling means functioning and deallocation.
  • Keeps informed about the errors and dangers happening in the system.
  • Establishes a good rapport between user and computer programs.
By now all of you must know what Operating System works (Function of Operating System) So let us now know how many types of OS are there.

Types Of Operating System
Technology is changing every day and with everything changing it, the same way, the use of the operating system is increasing in every field like Railways, Research, Satellite, Industry know how many types of operating systems are.
  1. Simple Batch system
  2. Multiprogramming Batch System
  3. Multiprocessor System
  4. Distributed Operating System
  5. Real-Time Operating System
1. Simple Batch System


This is the oldest system in which there was no direct interaction between user and computer. In this system, the user had to move a storage unit to process the task or job and had to submit it to the computer operator. There were lots of jobs given to computers in a batch or line. Within a few days or a few months it was a job process and an Output Device had an Output Store. This system used to process jobs in the batch so the name was also called batch mode operating system.

Disadvantages
  • 1. There is no direct interaction between user and computer.
  • 2. The job that comes first is job before the job, so the user had to wait more.
2. Multi Programming Batch Systems
In this operating system, a job was picked up from memory and it was executed. If the OS keeps working for a job, then if I want to do the same thing, then the OS gives the dusse job to the CPU and the CPU is always busy due to i / o for the first one. The amount of jobs in memory is always less than the number of jobs in the disk. If all jobs are in line, then the operating system decides which process will be the first process. The CPU is not always b-idle in this OS.

Time sharing system is also a part of the multi programming system. Response time is much less in Time Sharing System, but CPU usage is much higher in multi programming.

3. Multiprocessor System
Many processors use a Common Physical Memory in the Multiprocessor system. Computing power is quite fast. All these processors work inside an operating system. Here are some of its Advantages given below

Advantages
  1. The speed is too much because Multiprocessor is used.
  2. Many Tasks are processed simultaneously, so the System Throughput increases here. Which means, how many job processes can be in a second.
  3. In this OS the task is divided into the sub task, and each sub task is given to different processors, especially for this reason a task is completed in a very short time.
4. Distributed Operating System
The only purpose of using Distributed Operating System is that this world has a powerful OS and microprocessor has become quite cheap, as well as there is considerable improvement in Communication Technology. Due to this advancement, now the Distributed OS is built, its price is very cheap and it stops far-away computers via network. Which is a big achievement in itself.

Advantages
  1. Anyone who has far-reaching resources can be easily used, resources which are not empty.
  2. Processing them is fast.
  3. Load is less on the host machine, as Load Distribute happens.
5. Real Time Operating System
This is the most advanced operation system, which means the actual time process is Missile, Railway ticket Booking, while leaving the satellite, if there is a delay of one second, then everything in the water, this Operating System is not idle at all. . This is the kind of two types

1.Hard Real Time Operating System


This is the operating system which, at the time when it is time to complete the task, the work is done within the same time.
2.Soft Real Time
The restriction of time in Soft Real Time would be a little less what would happen if a Task is going on and at the same time some other Task comes, then the new Task is given Priority first. These were some information Types Of Operating system Before you know what is Operating System

My final decision:-
So friends today's information is quite important. So it is more important for a particular student. Now if the question comes in the exam
  • What is the operating system and
  • Explain Function and Types of Operating System
So you can easily answer it. Well, according to me, the OS is rapidly bringing new features, like talking about Windows 10. Because at the beginning it was said that the computer has the heart of the OS.
