Imagine you have a computer but can’t interact with it. Without a clear interface, how can you run your favorite applications, connect to the internet, or even manage your files? This is where the Operating System (Operating System – OS) comes into play. The operating system is the beating heart of any digital device, creating a bridge between hardware and software. Without it, computers and smartphones would be just useless pieces of equipment. In this article today from HiData, we comprehensively introduce the types of operating systems, their features, and their vital role in the world of technology.
What is an Operating System?
An operating system (software that manages computer hardware resources) is software that manages the hardware and software resources of a computer or other digital devices and processes user commands. This basic software enables the execution of programs, file management, data security, and communication between hardware and software.
What are the Main Functions of an Operating System?
The operating system (OS), as the intermediary software between the user and the hardware, plays a crucial role in managing resources and executing programs. Below, we examine the most important functions of an operating system:
۱. System Resource Management
One of the primary functions of the operating system is the effective management of hardware resources such as the CPU (Central Processing Unit), RAM (Random Access Memory), disks, and input/output devices. By intelligently allocating these resources to programs, the operating system prevents interference and performance degradation.
۲. Process Management
The operating system is responsible for creating, scheduling, stopping, and executing processes (running programs). This includes concurrency control and management of background processes to ensure optimal resource utilization and maintain system performance.
۳. Memory Management
The operating system must dynamically allocate memory to programs and release resources after their execution is complete. This management includes virtual memory, paging, and memory protection to prevent data corruption.
4. File and Data Management
The operating system enables creating, reading, writing, editing, saving, and deleting files. It also ensures data security and integrity by organizing the file structure (such as directories and access levels).
5. Providing a User Interface
The operating system provides a graphical (GUI) or text-based (CLI) environment for user interaction with the system. This interface enables the user to easily execute commands, manage files, and launch applications.

Types of Operating Systems and Their Applications
1. Desktop Operating Systems
A Desktop Operating System is software that manages resources, executes applications, and handles hardware interaction on personal computers, laptops, and workstations. These operating systems provide a graphical and user-friendly environment for running software, managing files, connecting to the internet, and everyday computer use.
In this section, we will become familiar with three main and widely used operating systems in the desktop world:
Windows (Windows)
Windows, a Microsoft product, is the most widely used desktop operating system in the world. Its simple user interface, support for a wide range of software and games, and broad compatibility with various hardware are factors contributing to the popularity of this operating system.
Features:
- Simple and familiar graphical interface for general users
- Extensive execution of commercial and educational software
- Suitable for general users, administrative staff, and gamers
- Various versions (Home, Pro, Enterprise, etc.)
macOS (macOS)
macOS is an operating system designed exclusively for Apple computers (Mac). Apple’s focus on design, security, and seamless integration between software and hardware provides a smooth and stable experience for users.
Features:
- Beautiful and minimalist design
- High security and protection against malware
- Seamless integration with other Apple devices (iPhone, iPad)
- Suitable for professionals in design, video editing, music, and programming
Linux (Linux)
Linux is an Open Source operating system that comes in various versions or distributions (such as Ubuntu, Fedora, Debian). Although it has a smaller share in the consumer market compared to Windows and macOS, it holds a special place among developers, server administrators, and professional users.
Features:
- Completely free and open source
- High security and unparalleled stability
- Full customization possibilities
- Suitable for software development, programming, networking, and servers
2. Mobile Operating Systems
These systems are designed for smartphones and tablets:
- Android: The most popular mobile operating system developed by Google and is open source.
- iOS (iPhone Operating System): Apple’s proprietary operating system used for iPhones and iPads.
3. Server Operating Systems
Server systems are designed for managing networks, databases, and cloud services:
- Windows Server: Developed by Microsoft for managing corporate networks.
- Linux Server: Various Linux distributions such as Ubuntu Server and CentOS are popular in server environments.
4. Embedded Operating Systems
These operating systems are used in devices such as cars, smart TVs, routers, and IoT devices:
- FreeRTOS: An open-source operating system for embedded devices.
- VxWorks: A stable operating system for industrial and medical equipment.
5. Real-Time Operating Systems (RTOS)
It is used for real-time data processing and is mostly used in sensitive industries such as medicine, aerospace, and automotive.
Key Features of a Good Operating System
Choosing the right operating system has a direct impact on efficiency, security, and user experience. A good operating system should be able to meet the needs of both users and developers simultaneously. In the following, we will get acquainted with its most important features:
۱. High Stability and Security
The operating system must be resistant to software errors and security attacks, and remain stable in long-term operation without crashes or performance degradation. High security is ensured by continuous updates, permission management, and intrusion prevention mechanisms.
۲. Simple and Smooth User Interface
A suitable user interface (UI) increases productivity and user satisfaction. The operating system should provide a smooth, understandable, and customizable experience for users at different levels (from beginner to professional).
