What is an operating system?
An operating system is software that acts as an interface between the computer (or device) and the user. It serves as a mediator between the various hardware components of the computer and the programs you use on a daily basis. Here are some of its essential functions:
- Resource Management: The operating systems manage access to hardware resources such as the processor, memory, storage, and peripherals. They ensure that programs run in an orderly manner and do not compete for resources..
- User interface : The operating systems provide a graphical user interface (GUI) that allows users to communicate with the computer in a user-friendly manner. It is the part of the OS that you see and interact with.
- File Management : Operating systems manage the storage and organization of files and folders on your device. They allow you to create, move, copy, and delete files..
- Security: Operating systems are responsible for the security of your device. They provide protection mechanisms against malware, as well as permissions to control access to data and features..
Types of operating systems
There are different types of operating systems, suited to different types of devices and uses. The main types of OS include:
- Desktop operating systems : These operating systems are designed for desktop and laptop computers. Examples include Microsoft Windows, Apple's macOS, and various Linux distributions..
- Mobile operating systems: These operating systems are specially designed for smartphones and tablets. The most popular are Google's Android and Apple's iOS..
- Embedded operating systems : These operating systems are integrated into specific devices, such as GPS navigation systems, smart home appliances, and even automobiles. Linux and customized variants are commonly used in this field..
- Server operating systems: These operating systems are optimized for running servers and data centers. Linux (notably with distributions like Ubuntu Server and Red Hat Enterprise Linux) and Windows Server are well-known examples..
