Introduction: Operating System

An operating system (OS) is a software that manages a computer’s hardware resources and provides services for running applications. The operating system is responsible for managing the computer’s CPU, memory, storage devices, and other hardware components. It also provides a user interface that allows users to interact with the computer and run applications.

An operating system is essential for the proper functioning of a computer system. It acts as a bridge between the hardware components and the software applications. The operating system provides an environment in which applications can run, and it manages system resources to ensure that applications run efficiently.

There are several different types of operating systems, including Windows, macOS, Linux, and mobile operating systems like Android and iOS. Each operating system has its unique features, user interface, and system requirements.

Operating systems have evolved over the years, becoming more user-friendly and efficient. Modern operating systems offer features such as multitasking, virtual memory, and security features like user accounts, passwords, and permissions.

IT support professionals often work with operating systems, troubleshooting issues such as software bugs, system crashes, and performance issues. They may also perform maintenance tasks such as updating the operating system, installing security patches, and optimizing system performance.
