Operating Systems are the backbone of any computing device from smartphones that we all are using to servers. They manages hardware, software and the user interactions. In this blog we will explore the types of operating system, their features and real world examples to help you understand about it.
What is an Operating System?
Operating System is a system software that helps users to interact with the computer system. Without OS, user will not able to interact with a computer in a meaningful way. The Operating System ensures that all hardware components like CPU, memory, hard drives as well as input/output devices work together efficiently without any conflict.
There are several functions of operating system are there which includes :
- Resource Management : It allocates and manages the CPU time, memory space, disk usage, and other system resources.
- File Management : OS manages the files & directories as it allows easy storage and retrieval.
- Process Management : Handles creation, scheduling and termination of processes (running applications or tasks).
Common examples of Operating System are Windows OS, MacOS, Linux, Android and iOS.
Why are Operating Systems Important?
Operating Systems are the backbone of any computing device. Without them, computer would not be able to function efficiently.
Memory Management : The operating system allocates memory to various applications and manages how data is stored and retrieved. This ensures smooth performance and avoids system crash.
Device Control : Operating system manages all input and output devices like keyboards, mouse, printers, and USB drives. This allows the users to interact with the hardware effortlessly.
Multitasking : One of the most powerful features of modern operating systems is their ability to run multiple applications at once. Whether you are browsing, playing music, or working on a document, the operating system schedules and manages the resources effectively.
System Security : Operating system ensure application’s security which includes user authentication, data protection and access control. OS protects system from any kind of attack happens on a system especially cyber attacks.
Types of Operating System
Understanding the different types of operating system is essential for anyone looking to explore how computers, servers, mobile devices and embedded systems functions well. Each type serves a specific purpose, and the features they offer depending on the environment they designed for. Below, we’ll explore the major types of operating systems in detail, along with their use cases and examples.
Batch Operating System
One of the earliest types of operating system and is widely used in the era of mainframe computing. In this system, users don’t directly interact with the computer. Instead they submit jobs to the system operator, who collects and organizes similar jobs into batches. These batches processed sequentially without user interactions.
Batch Operating System is specially designed for the environment where tasks are repetitive and does not required real-time feedback.
IBM OS/360 is a classic example of a batch operating system.
Time-Sharing Operating System
Time-Sharing Operating System comes with a great advancement in the evolutions of the types of operating system . This System allows multiple users to access a single computer at a same time by assigning a time slot to each user.
Time-sharing systems are ideal for multi-user environments and ensure efficient CPU utilization, reduced idle time, and improved user interaction.
UNIX and MULTICS are widely recognized examples of time-sharing operating systems.
Distributed Operating System
A distributed operating system is a modern and one of the complex types of operating system that manages multiple computers and presents them as a unified system. These systems work together to share resources like processing power, memory, and data storage.
This type of operating system is particularly useful in cloud environments, research centers, and clustered networks where performance, redundancy, and resource distribution are critical.
Example: LOCUS and Amoeba are examples of distributed operating systems.
Network Operating System
Among the various types of operating systems, the network operating system is designed specifically to manage network resources and ensure smooth communication between connected devices. Unlike distributed operating system, each device in a network operating system setup remains independent but works together through the network.
Network operating systems offer features such as file sharing, printer access, security management, and user administration across a local or wide area network.
Windows Server and Novell NetWare are commonly used network operating systems in enterprise environments.
Real-Time Operating System
The Real-Time Operating System (RTOS) is a special type of operating system that ensures instant response to inputs and guarantees timely processing. These systems are crucial in scenarios where delays can lead to critical failures, such as in medical devices, aircraft systems, and robotics.
It responds within a guaranteed time limit, making it ideal for embedded and mission-critical systems like in satellites.
VxWorks and RTLinux are trusted real-time operating systems used in industries today.
Mobile Operating System
With the rise of smartphones and wearable devices, the mobile operating system has become one of the most widely used types of operating systems today. Designed for touch-based devices and mobile operating systems focus on smooth user experience, app performance, and connectivity features.
They manage mobile-specific tasks like GPS, camera, and app store integration, while ensuring security and battery optimization.
Android and iOS are leading mobile operating systems that dominate the global market.
