Foundational Software Running Devices

The OS is the main software that governs how a device's hardware works and provides an environment where applications can run. The OS is responsible for managing the many facets of computing, including:

* Memory allocation

* File management

* Security permissions

* Network connectivity

* User interaction

Examples of popular operating systems include Windows, macOS, Linux distributions, Android, and iOS.

Without an OS, computers and mobile devices would be unable to carry out even the most basic functions. The OS serves as a conduit between the hardware and all of the programmes that users rely on every day to accomplish their tasks and to run their daily lives: it manages the different processes that need to run in concert with each other and makes sure everything runs efficiently and safely.

Modern operating systems provide users with many features that facilitate the use of computers and other digital devices:

* Graphical user interfaces

* Voice-activated assistants

* Multitasking capabilities

* Notifications

* Accessibility features

Operating systems receive updates to eliminate security vulnerabilities, improve performance, and introduce new features and capabilities.

As a developer, you must be familiar with an OS's architecture to design and develop applications that work well with the OS and deliver optimum results for the user. The operating system provides the overall feel and user interface of your computer. It serves as the silent engine driving all of your digital interactions.
