OS

The operating system (OS) is software that manages computer resources and enables the launch and execution of other applications. The OS provides user convenience, manages the file system, data input and output, memory, and the processor, ensuring the security and confidentiality of information, among other functions.

Modern OSs such as Windows, MacOS, Linux, iOS, Android, and others typically have a graphical user interface, making computer usage more user-friendly. The OSs may also support multitasking, multi-user access, resource virtualization, and other advanced features.

The OS plays a crucial role in computer operation, serving as the primary layer of software between the computer's hardware and its applications, allowing them to interact and function together.

Tailored for particular uses, operating systems are categorized into distinct types, encompassing desktop OSs for PCs and laptops, server OSs for resource management on servers, mobile OSs for smartphones and tablets, and embedded OSs for Internet of Things devices. The principal role of file systems is to facilitate access to data stored on storage media.

Increasingly, OSs integrate additional features such as multitasking, multi-user access, network support, data protection, resource virtualization, and artificial intelligence. Different distributions and versions of OSs support varying hardware and functionality, allowing users to select and customize the OS according to their needs and preferences.
