Operating System Concepts What is an OS (Definition)

Hey, welcome to the course another time. I'm excited to show you this course and that I am sure you'll enjoy it too. So let's start the primary section.

The first lecture what's an Operating system. Now, this is often the place to begin for anyone who has to study operating systems. This can be the basic question that may come to your mind.

So let's start with this question. First, during this article we'll discuss two topics to know what's an Operating system. First, you may have a look at the definition of an Operating System and we will try and understand its meaning moreover and within the second topic, we are going to see where exactly an Operating System fits within the overall ADPS or Computer System.

This will help you to understand the role played by an operating system within the functioning of a computer. So let's start whenever you turn on your laptop desktop tablet or a mobile device you may have observed that it takes a while to load your home screen.

Here your device is starting software within the background and this software will help you you to control your computer or mobile device and permits you to run other applications on top of it. This software is running as long as your device is running and it stops only when your device shuts down.

If you're even remotely a tech-savvy person you may know what this software is it's an software. To define it formally an operating system is an important part of a program that manages the pc hardware and other software applications.

Using a package you'll be able to utilize the hardware components like CPU memory input and output devices like keyboard mouse etc. So therefore a package also acts as an intermediate between the pc hardware and you the pc user.

You can say it acts as a middleman. This is often because the user cannot give commands on to the CP in machine language nor can the CPU interact with the user directly so there must be a middleman that communicates and translates all interactions between the user and also the CPU.

Now let's have a look at where exactly the operating system fits within the overall ADPS or System structure. A computer can be divided into four components and at the core, we have the hardware which comprises CPU memory and other i/o devices.

On top of this, there's an OS that controls and coordinates the utilization of hardware by various applications. Application programs are the software tools or utilities that the users run to hold out their tasks.

These programs can utilize hardware resources through the assistance of operating systems. Some samples of application programs are the word processors spreadsheets compilers and even the browser you've got opened right away to look at this text.

And finally, on the opposite end, we have the important computer users who interact with the pc in order to get some tasks performed. So based on this figure here you'll see that the software system occupies an important part within the architecture of an automatic data processing system.

Without operating systems, it might be very difficult to utilize the pc effectively. In order that should offer you a basic idea about what's an OS. If you continue to have any queries post it on the discussion forum or comment below and that I shall answer it for you.

As far because the exercise for this subject is concerned it's very simple. Create a definition of what's an Operating System in your own words and this can help you to place your understanding in words and it'll also help others to get a special perspective of the same definition.
