The operating system is the basic software for managing hardware resources, running programs, and providing user interaction interfaces. It coordinates the relationship between hardware and software and is responsible for memory allocation, device scheduling, file management and multitasking. Common systems include Windows (suitable for office and gaming), macOS (Apple devices, suitable for creative work), Linux (open source, suitable for developers), and Android/iOS (mobile device system). The choice of ordinary users depends on the usage scenario, such as software compatibility, security and customization requirements. How to view system information: Use winver command for Windows, click on the machine for macOS, use terminal commands for Linux, and find the phone in settings. The operating system is the underlying tool for daily use, which directly affects the function and experience of the device.
An operating system (OS) is the software at the lowest level of a computer or device. It is responsible for managing hardware resources, running programs, processing files, and providing an interface for users to interact with the device. You can think of it as the foundation of a house, without it, other software is like furniture that has nowhere to be placed.
What exactly is it doing?
The core task of an operating system is to coordinate the relationship between hardware and software. For example, if you open a browser, the operating system actually assists you in allocating memory, calling the CPU, and reading data from the hard disk. It is also responsible for scheduling of multiple programs when they run simultaneously, ensuring that they do not interfere with each other.
Common features include:
- Manage files and folders
- Control input and output devices (such as keyboard, mouse, printer)
- Provide network connection support
- Run and manage applications
What are the common operating systems?
There are several mainstream operating systems on the market, each suitable for different scenarios:
- Windows : The most widely used desktop system for office, gaming and general purpose.
- macOS : A dedicated system for Apple computers, with a simple interface, suitable for creative workers.
- Linux : Open source system, suitable for developers and technicians, and has many distributions (such as Ubuntu and Fedora).
- Android/iOS : Operating system on mobile devices, used for Android phones and iPhones respectively.
Although they look different, their underlying logic is similar, but they are targeted at different user groups and usage methods.
What does an operating system mean for ordinary users?
For most people, the operating system determines which software you can use, how to operate the device, and how safe and stable the device is.
For example:
- If you are using Windows, you can install various office software, games, and even virtual machines to run other systems;
- If you are using a MacBook, it may be more suitable to use Final Cut Pro to cut videos, or use Xcode to develop iOS applications;
- And if you are using Linux, it may be to customize the system more freely, or learn programming.
Which system to choose actually depends to a large extent on what you are going to use for.
How do you know which system you are using?
It's actually very simple to know which operating system your device is running on:
- Windows: Press
Win R, enterwinver, and press Enter to see the version information. - macOS: Click the Apple icon in the upper left corner → About this Mac.
- Linux: Open the terminal and enter
uname -aorcat /etc/os-release. - Mobile: Find "About Mobile" or "System Information" in the settings.
Basically that simple. The operating system sounds quite technical, but it is actually the basic tool you deal with every day.
