Answer (1)
The correct answer is D. A set of programs that manages the computer's resources.
An operating system (OS) is a crucial type of software on your computer that performs a variety of essential tasks. It acts as a manager for all other programs you use, helping them run smoothly and work together efficiently. Here’s a simple breakdown of what an operating system does:
Resource Management : The OS manages the computer’s hardware resources, such as the CPU, memory, disk space, and input/output devices. It assigns the necessary resources to each application when they need them.
User Interface : It provides a user interface, which can be graphical (like Windows or macOS) or command-line based (like Linux or older versions of DOS), allowing you to interact with the computer easily.
File Management : Operating systems organize and track where information is stored on your computer’s hard drive, so you can save, find, and retrieve files quickly.
Multitasking : The OS allows multiple applications to run simultaneously, like browsing the web, writing documents, and listening to music, by managing the available processor time and memory.
Security and Access Control : It helps protect your data and system integrity by controlling access to files and resources, ensuring that unauthorized users can't misuse the system.
In summary, an operating system is essential because it serves as the foundation that allows you to interact with your computer and allows other software to function properly.
