Hello Friend welcome to IATechnicalHindi.com Do you know what is the operating system (What is Operating System?) Even if you do not know, do not panic, we will answer it and it will be answered with some more 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 the hearts of humans, the computer also has 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 that the computer’s heart means what the work of this OS is. In a small sense, you would like to give people that an operating system is a type of interface between end user and hardware. Well, how many types are these, where are they used, what are their main tasks, if you want to know more then what is this article operating system? Must have read it. So let’s begin without delay and know about Operating System.

What is 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, you double click on the word document, if you sit down at the bottom of the window, 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. That’s why whenever you buy a new computer, first of all you have to load Window 8 or Windows10 to the shopper, 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 did it call 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 only see this operating system 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

Well the computer does a lot of work, but first of all when you are on the computer, the operating system first loads the main memory in the sense of RAM and after that allocate all of the software to the user software from the cone angle. Different types of lower OS 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. Telling the Error
8. Reconciliation between Software and User

Memory Management

Memory Management means managing primary and secondary memory. Main memory means RAM is a bottle of big Array bytes. Meaning, there are all small pieces of boats 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 only. the 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, the OS takes back its memory.

Processor Management (Process Scheduling)

When talking about multiprogramming 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. The operating system does all this work.

• The operating system also sees that the processor is empty or something is working, or is free and whether the process has finished its work or not. If you wish, 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.
• CPU does allocate to the process.
• When a process is finished, then he takes the processor into a different job, and when the work is done, the processor is free.

Device Management

You have to use a driver in the computer, you must know it, 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 the different processes, Devices should do some task, so even the OS does the task of allocate. Take an example of a process that has to do some tasks such as video play, print not removed, then both of these Task Output device Monitor will be done with the help of printer. So when these two devices have to give a process, it does the OS.
• When the process is finished, then it deallocate the device back.
