Friends everybody knows about the operating system. Because we use it throughout our computer or mobile every day.
But do you know what an operating system is? what are the types of operating systems and the importance of operating systems?
Nowadays mobile and the internet have become a big part of our lives. Without which we can’t do anything nowadays. Similarly, mobile and computer operating systems work like this.
There are many organs in the human body, which help us to do. If any organ stops working, we can survive.
But if the main thing of the body, the soul is taken out, then all the organs of the body do not work.
This is exactly the situation with our computer or mobile without os. After making a computer or mobile with different hardware, if the operating system is not installed in them, then that mobile or computer will not start.
For this, the operating system is very important for any mobile, computer, or tablet.
In today’s article, I will discuss all the information related to the operating system. You will find information on what the operating system is, how many types of operating systems there are, and how the operating system works, from this article.
Hope you are interested in all this information about the operating system. If yes, stay with me till the end of this article.
What is an operating system?
The operating system is also called os on short from. It is system software that performs all the functions of the hardware and software inside the computer.
An operating system is a software that creates an interface between a user and a computer. Which allows the user to communicate with the computer. And for this, the user does not need to understand the language of the computer.
All computers need an operating system to work properly and also to run any other program or application.
Applications such as Google chrome, Ms Word, Photoshop, and games require a medium or platform to run, and it provides by the operating system.
Computer like an empty box without an operating system. The operating system of a computer is a combination of many small programs. Which are stored together on the computer’s hard drive.
These programs manage computer resources such as hardware and their functions. Computer hardware cannot work on its own, nor can it interact with each other.
This is why the electronic signals created by the operating system help complete the hardware’s work.
The operating system is the first program installed on a computer. Which acts as a bridge between the computer’s hardware and software. So that hardware and software can easily interact with each other.
Operating systems have different names but all work like the same. Os help to communicate the user with the computer and manage the hardware.
Operating system examples
Some of the major operating systems are windows operating system, mac os, Linux os, Ubuntu, android, ios, ms-dos, Symbian os.
Now we will know what the operating system does.
The function of operating system
The operating system is the most important program of the computer. Which do all types of common and important works.
Such as understanding the key input from the keyboard and displaying the output on the screen, managing the files and directories on the hard disk, and managing all the parts on the computer.
Operating systems are also capable of performing a variety of tasks such as:
1. Memory management
Managing primary memory or main memory is called memory management. The operating system tracks all the functions of the primary memory. This means how much memory is being used for any purpose or how much idle is there.
Keeps track of where memory is being used or how much is being used and supplies that amount of memory if needed.
During multiprocessing, the operating system decides when and how much memory will be available in any processing. When a program finishes its work, the operating system conserves the allocated memory in the initial state.
2. Processor management
In the multi-programming situation, the operating system decides when and for how long the processor needs to manage any program. This method is called process scheduling.
Os monitors the status of the processor and processing. The program from OS which requires to manage this method is called Traffic Controller.
3. Device management
The operating system manages devices communication through its own drivers. This OS monitors all devices. Which program from the OS requires for this task is called the input-output controller.
The operating system determines which process is required for the device or for how long. And when the operation of the device is completed, Then OS makes the device inactive.
4. File management
The file system is migrated to the directory for easy navigation and adaptation. Os monitors the source, location, user, status, etc. of these files.
Os tracks every source. As well as the location of the file, when the file was created, the size of the file, and which user made it. OS records all the information.
The operating system protects our system from unauthorized access. This means that no unknown user can use the system without your permission. And for this os gives full permission to give passwords to your computer.
When you turn on your computer, the first thing you will be asked for a password. This will keep your system safe.
Types of operating system
Now we will know how many types of operating systems are there. Technology is also evolving with the change of time. As a result, computers are also improving a lot.
OS has been in use since the computer was used. As the computer changes and the operating system is also being improved, the computer is compatible with it.
There are many types of os, for example
1. Multiuser os
This operating system allows many users to work together. This os is used on the computer network. Where the same data or application can be used by more than one user at a time.
2. Single-user os
This operating system allows only one user to operate at a time. Generally, this single-user operating system is used for personal computers.
3. Multitasking os
This operating system allows the user to run many programs simultaneously. For example, you can listen songs as well as write emails and use Facebook.
4. Multiprocessing os
In Multiprocessing os two or more processors are connected to each other. It means that more than one processor is involved in processing if any program running from your computer system.
5. what is a network operating system?
Network operating systems are used on those computers where all computers are connected to the same network.
It is a type of operating system that helps multiple computers to communicate together and transfer data from one computer to another. Generally, a network operating system is used in the server.
6. what is distributed operating system?
Distributed operating systems are used where we need to store and transfer data. Many central processors are used in distributed os. And these processors are divided into different processing.
Importance of operating system
Friends, have you ever used your computer without an operating system? If yes then you can feel the importance of the operating system.
Without a soul, our body can’t work, Similarly, the computer is useless without the os. The operating system helps the user to use a computer without knowing its language.
FAQ’s on the operating system
Below are some questions related to os which people also ask for answers. So I include them in this article for my readers.
Q1. What are the 4 types of operating systems?
Actually, there are many types of operating systems. But the main types of operating systems are :
1. Batch operating system
In a batch operating system user cannot interact with the operating system directly. Here an operator takes the jobs from the user and groups them into batches.
In a batch operating system, multiple users can share the batch systems. But it can costly and hard to debug.
2. Multiprogramming operating system
In multiprogramming operating systems many programs run at the same time. In multiprogramming operating system didn’t need to be multiprocessing.
Generally, at a time, one program is processed by the CPU. But for the speed of processing, we can’t understand.
3. Time-sharing operating system
The time-sharing operating system is the updated version of multiprogramming os. It has the ability to handle multiple interactive jobs and here the processor time is shared among multiple users.
4. Distributed operating system
It is the collection of independent computers that are interconnected via a network capable of collaborating on a task.
Q2. What is the best free operating system?
There are many operating systems available. But the best and free operating systems are
Ms windows, Linux, Mac os, chrome os, Solaris, and Free BSD.
Q3. Is Google OS free?
You can use the free and open-source version of chromium os.
Q4. Does Google have an operating system?
Yes, Android, the most widely used operating system for mobile.
