What are an Operating System and its features? If you are unfamiliar with the operating system, What is an operating system? It doesn’t matter because you will understand well after reading this post today.
You will also learn about the various types of operating systems and how they function. All of these questions will be answered if you read this post completely.
Friends, there are numerous parts of the human body that are required for survival. However, the soul is such a thing that if it is not present, the human body is useless. The entire body functions as long as the soul is present.
A person lives whether or not a component works. In the same way, a computer has a soul, which we call the operating system.
You only understand what a computer is. It also has a lot of parts. However, the computer will not function until this occurs.
Introduction to Operating System
The operating system, or OS for short, is a type of system software. It’s similar to a soul in a computer. Without it, the computer cannot function.
It handles all communication between computer hardware and software. This is a kind of interface between the hardware and the users, or between us, that connects us.
To put it another way, there is a foundation upon which all software and hardware operate. All hardware, such as a keyboard, mouse, and printer, as well as software such as Microsoft Office, Photoshop, and Chrome, are compatible with all operating systems.
Take, for example, a house. What good are bricks, cement, and sand if there is no land on which to build a house? So, will you build a house without any land?
Your response would be no! In the same way, if you want to run the computer and have all the necessary components such as a mouse, keyboard, and printer but the operating system is not installed, you have correctly deduced that the computer will not boot.
If you go to the store and buy a new computer, install Windows 7 or 10 on it and give it to someone. Assume that if you take it home without installing Windows, you understand that you will have to return to the shop.
Because without it, your computer will not boot.
Application software includes Microsoft Word and VLC Player. System software refers to the software that we use and the software that the computer uses.
The operating system is the system software in this case. Now that you’ve figured out what this is, let’s go over some more details.
The function of the Operating System
The computer works because of this, but it is also important to understand how it works. How is the computer able to run from the time it boots up until it is turned off by handling all of the work on its own? This is something to consider. So, tell us about computer functions.
- Memory management
- Processor management
- File management
- Device management
- Control over System Performance
- Job Accounting
- Error detecting aids
- Coordination between other software and users
Memory management refers to the process of managing primary and secondary memory. RAM (random access memory) is a type of volatile memory. And whoever works on the documents, they are kept in temporary storage. Main memory is made up of many arrays of words or bits, each with its own address. Fast main memory that can be accessed directly from the CPU.
Any software that we open by double-clicking it must be in memory. Let’s take a quick look at what else it can do.
- Every step of the primary memory is recorded. For example, how much memory is used and who is using it. For example, if we use Chrome, how much memory does it consume? If the music player is also running, it will consume some RAM separately. It displays all of this information.
- In multi-programming, the operating system determines which processes receive how much memory and when.
- When multiple programs are launched, the memory for the program is distributed.
- When a program is closed, memory is saved.
In a multi-programming environment, the operating system decides which process gets the processor, when it gets it, and how long it gets it. This is also known as process scheduling. To manage the process, it performs the following tasks.
- The operating system monitors all of the processor’s activity and records the status of each process.
- The person in charge of this task is known as the traffic controller.
- It assigns the processor to any process.
- When a process halts, it reintroduces it.
Every input and output device comes with a driver that allows you to install it. Before we can use any of these input or external devices, we must first install the driver.
If the driver is not installed, the computer will not recognize the device. As a result, the device is rendered inoperable.
Although drivers had to be installed for all devices in the OS up until almost Windows 7, drivers are only required for a few devices in the latest Windows.
Through its driver, this device manages communication. Let’s take a look at how operating system device management works.
- It keeps track of all the devices. The program used to manage the devices is known as an I/O controller.
- The operating system also decides which processes to assign to the device, when and for how long. Take, for example, the Photoshop program. When you click on Print to print a photo in it, the OS printer, which is an output device, executes it for a while to process it. He returns the photo to the device once it has been printed.
- As I mentioned in the preceding example, use the device for as long as possible.
- When the device has finished its work, keep it inactive by turning it off.
To make it easier to use the file, we create a folder and keep it within it. This allows us to use any file at any time by storing it in a category-specific folder. The directory is also known as a folder.
Maintains additional folders and files within the folder. This way, we can see what other tasks the OS performs.
- It keeps track of everything. Along with this, it keeps information such as the file’s location, when it was created, its size, and the user who created it. The program that handles all of this is known as the file system.
- The operating system decides who gets the resource.
- They divide their resources amongst themselves.
- When resources are not in use, they are withdrawn.
We want computers that only we can use as we use more computers. As a result, it also provides us with security.
We can create users for ourselves and protect them with passwords. Even if there are multiple users, we can use it independently by creating a personal user for ourselves.
The system remains the same, but we can easily keep our personal data hidden, secure, and locked. This operating system provides us with all of the necessary tools.
Control Over System Performance
You must have had the experience of wanting to start a program and it starts after a while.
Or you may have attempted to save some of your files and it is currently processing. The operating system records all of these delays or performance delays, as well as how long it takes after the system has responded to complete a process.
The operating system also works on what tasks a user did until the computer was started and shut down. It also keeps track of which file the work is done in.
Error Detecting Aids
Many times it happens that software and programs hang while working. And it also happens that due to some error, the software stops in the middle. The OS also keeps track of all these errors.
Coordination Between other Software and Users
The operating system (OS) coordinates the programming languages that run inside the computer and the commands and inputs provided by the users.
When we type “aa,” for example, the system recognizes what we’ve written based on the (0,1) code. Then it processes it and understands the programming language, and finally, it understands it and displays it to us via the output device.
The platform to work in the middle for all of this performance is the OS itself.
Types of Operating Systems
Every day, something new happens in the world. Similarly, the computer’s operating system (OS) is constantly changing. Technology continues to advance.
Scientists have now achieved a great deal of success in the field of artificial intelligence.
This is not possible if the operating system does not change. NASA has now arrived on Mars. So, can you guess that your home operating system will be used in rocket science?
No, very advanced operating systems with cutting-edge features are used for this. You must have realized by now that there is more than one type.
It is classified into several types based on its intended use and requirements. It is only used when necessary. So, how many different kinds of operating systems are there?
- Batch operating System
- Network Operating System
- Time-Sharing Operating System
- Distributed Operating System
- Real-Time Operating System
Characteristics of Operating
- An operating system is a collection of many software programs that serve as the foundation for other programs to run on.
- It is critical to have an operating system in order to install all of the software.
- The operating system manages all of the computer’s input and output devices.
- It serves as a bridge between the user and the hardware. That is, when we enter data using the keyboard and mouse, the operating system controls it and displays it to us via the output device.
- It also provides security if we want to keep our data safe. It also provides us with numerous features for this purpose.
Friends, you must have realized how this works by now.
I hope you have received all of this information. With the advancement of technology, something new is being added every day.
We frequently get many new features by updating them on a regular basis. So, how did you like today’s post, friends?
Friends, today’s information is critical; if you are studying computer courses and operating systems, you must understand what an operating system is. What exactly is an operating system?
Along with this, it is necessary to gather information on how many different types of operating systems exist.
