* Hardware Abstraction: The OS presents a standardized interface to the user, hiding the complexities of the underlying hardware. You don't need to know the specific details of your hard drive or graphics card to use your computer; the OS handles those interactions.
* Resource Management: The OS manages the computer's resources, such as memory, CPU, and storage devices, ensuring that applications can access them efficiently and without conflict.
* Device Drivers: The OS uses device drivers, small programs that translate instructions from applications into signals understood by specific hardware components.
* Security: The OS enforces security measures to protect the system from unauthorized access and malicious software.
In short, the OS acts as a software layer that allows users and applications to interact with the hardware without needing to understand the intricate details of each individual component.
