Operating systems (OS) are the backbone of every computing device, from smartphones to servers. The world of operating systems is vast and constantly evolving. Navigating this world can be challenging, especially for newcomers.
The purpose of this blog is, we’ll take a look at some of the key aspects of operating systems and provide guidance on how to explore and learn about them.
What is an Operating System?
An operating system is a software that manages the hardware and software resources of a computing device. It acts as an interface between the hardware and the applications that run on top of it. Operating systems come in different forms, ranging from desktop operating systems like Windows, macOS, and Linux to mobile operating systems like iOS and Android.
Where We Use Operating Systems?
Operating systems are used on various computing devices, such as personal computers, servers, smartphones, and embedded systems. They are present in almost every electronic device that has a computing capability. The most common use of operating systems is in personal computers and laptops.
Types of Operating Systems
There are several types of operating systems, which are classified based on their functionality and the hardware they run on. Here are some of the most common types of operating systems:
Single-User, Single-Tasking Operating Systems – These operating systems allow only one user to use the computer at a time and can perform only one task at a time. They are not commonly used in modern computing environments.
Single-User, Multi-Tasking Operating Systems – These operating systems allow one user to run multiple programs or tasks simultaneously. Examples include Microsoft Windows, macOS, and Linux.
Multi-User Operating Systems – These operating systems allow multiple users to use a computer system simultaneously. Examples include Unix and Linux.
Real-Time Operating Systems – These operating systems are used in embedded systems and have strict timing constraints. They are designed to respond to external events in real-time, with minimal delay.
Mobile Operating Systems – These operating systems are designed for use on mobile devices like smartphones and tablets. Examples include iOS and Android.
Which is the Most Popular Operating System?
The most popular operating system in the world is Microsoft Windows. As of September 2021, Windows had a market share of over 70%, followed by macOS with a market share of around 16%, and Linux with a market share of around 2%. Windows is the most popular operating system due to its ease of use, widespread availability, and compatibility with a wide range of software and hardware.
Learning about Operating Systems
There are several ways to learn about operating systems. One way is to read books and online resources about operating systems, such as the “Operating System Concepts” book by Silberschatz, Galvin, and Gagne. Another way is to take online courses and tutorials, such as the “Operating Systems and You” course offered by Google on Coursera. Hands-on experience with different operating systems is also important for learning about their features and capabilities. Setting up virtual machines or dual-booting different operating systems on a single machine can provide a good learning experience.
Conclusion
Navigating the world of operating systems can be challenging, but it is essential for anyone interested in computing. Understanding the basics of operating systems and their components is a good starting point for exploring this vast field. There are various resources available to learn about operating systems, including books, online courses, and hands-on experience. By gaining knowledge and experience in operating systems, you can open up new possibilities in computing and enhance your career opportunities.
