Operating systems (OS) are essential for managing and coordinating hardware and software resources on a computer or device. Here’s why operating systems are used
OS manages hardware resources such as the CPU, memory, and storage devices. It allocates these resources to different programs and processes to ensure efficient operation.
It provides a user interface (UI) that allows users to interact with the computer or device. This could be a graphical user interface (GUI) with windows and icons or a command-line interface (CLI).
OS handles file storage, organization, retrieval, and management on storage devices. It manages file systems, directories, and file permissions, ensuring data is properly stored and accessed.
It manages processes and tasks running on the system. This includes scheduling processes, managing multitasking, and handling process creation and termination.
OS controls and allocates memory space for programs and processes. It ensures that each process has enough memory and manages swapping data between RAM and storage when necessary.
It provides drivers and interfaces for various hardware devices (like printers, scanners, and USB devices) so that they can communicate with the computer.
OS implements security measures to protect data and system integrity. It manages user authentication, access permissions, and protects against unauthorized access and malicious software.
It manages network connections and communications, allowing computers to connect to and communicate over local networks or the internet.
OS provides a platform for applications to run, offering the necessary services and resources for applications to function effectively.
OS monitors and manages system errors, provides diagnostic tools, and offers troubleshooting options to maintain system stability and performance.
In summary, operating systems are fundamental because they provide the necessary infrastructure for a computer or device to function, ensuring that both hardware and software work together seamlessly and efficiently.
