What is an operating system?


Suppose you're trying to find out what OS definition is, then congratulations! You're at the right place. The operating system (OS) is practically described as the leading software or central nervous system of a computer that controls and coordinates the different parts of our computers. It supports all the other software and applications running on our computers, such as video games, web browsers, and office tools like Microsoft Word or Excel. Whenever the computer boots up or loads, the operating system will immediately run and supply instructions to all those other programs on how they should function for you to use them.

Functions of an operating system

Wherever in the world, you are, I can almost guarantee that there is an operating system being used that you are very familiar with. I'm willing to bet yours is different from where we live, but it's because it's been posted here. An operating system acts as the glue which holds a computer together -- it manages resources, the code which handles hardware and software, and serves as the middle man between the hardware and programs on your computer. It's one of the most crucial parts of your computer, but how well do you know yours?

Without an operating system, each application would function entirely independently of the one next to it. This doesn't sound too terrible until you add music and video players capable of playing both media formats simultaneously and another running the latest version of your favorite game. It would be complete mayhem! Applications on a computer need to work together. 

For example, if you drag files into a folder on your computer, and then you double-click that folder or right-click it, the files will open inside a program. And that program isn't necessarily a document viewer. This is because all applications have a function. You may have a text editor and a word processor installed on your computer. Still, they won't open in their correct filetypes unless they're designed to use the operating system.

Operating system types and examples

Types of Operating system


It is easy to see why there are so many different operating systems with such a diverse ecosystem. It seems that every computer manufacturer, with the exception of Microsoft, has made its operating system. The majority of devices ranging from mobile phones to television sets, can run on an OS of one of the many available options. Today, we will take a look at some of the more popular OS options that serve distinct needs throughout the industry.

Windows operating system 

Windows operating system


The Windows operating system is a renowned piece of computer software for desktops and laptops. Many users find it easy and convenient to use. The OS has been built with ease of access in mind and security so that your computer and data are always protected from viruses and other types of malicious software. Even though you can also download several free, open-source, or alternative operating systems these days, Windows is still the most widely used operating system worldwide. 

In this article, we will provide an overview of the many Windows versions released since Microsoft hit the market with its software and some more recent programs developed by the corporation. For fans of the Windows brand and anyone interested in finding out more about the product's history, continue reading.

Mac OS

Mac OS


OS X's first version, Mac OS X, was released to consumers in March 2001. Since then, seven more distinct systems have been released: Mac OS X Leopard (10.5), Mac OS X Snow Leopard (10.6), Mac OS X Lion (10.7), Mac OS X Mountain Lion (10.8), and the latest, OS X Mavericks (10.9). The system may have been changed drastically from time to time. Still, the interface has remained similar throughout, so you'll feel right at home when switching to a newer version.

Linux OS

Linux has been around for a long time. It first appeared in 1991, when an early version was packaged and sold by a student in Finland. Since its release, Linux has had an exciting journey. I'm not looking to write a history lesson – honestly, this article would be hundreds of pages and take me months to write. Instead, I will give you my top 5 reasons why it's worth giving this operating system a chance.

Mobile operating system

Mobile operating systems have been designed to fully utilize the computing capabilities of today's smartphones and tablets. Today's mobile devices are everywhere, and they're all powered by an OS. Smartphones have taken over the world, with 2 billion smartphone users all around the globe in 2016: that's a staggering 260 million smartphone users in the US alone!

A computer operating system (OS) is system software that manages computer hardware and software resources and provides standard services for computer programs. Time-sharing operating systems schedule tasks so that multiple programs can share the CPU simultaneously. In contrast, real-time operating systems allow each program to have a predictable CPU time, regardless of the number of tasks running. 

Operating systems perform a crucial function in all modern computers, from tiny embedded systems to large server computers, and are commonly known as one of three major instruction set architectures. The strength of an OS is based on its speed and ability to manage to compete for memory access requests from different applications or software threads. 

I hope right now you understand that-what is an operating system? How it's works and some examples of the operating system. I hope you enjoy my blog. Thanks
