Explanation

The Control Panel provides access to hardware settings and options.

Users can manage and configure hardware devices, such as printers, sound cards, and graphics cards.

Additional points:

• Device Manager: Manages and troubleshoots hardware devices
• System Properties: Displays system information and settings
• Settings App: Provides access to system settings, including hardware options (in Windows 10 and later)

Explanation

Devices like mouse, printer, and network adapters need specific drivers to communicate with the operating system.

Without drivers, the OS can't recognize or control these devices properly.

Explanation

A device driver is a program that controls and manages a specific type of device attached to a computer, such as a printer, mouse, or keyboard.

It allows the operating system and other software to communicate with the hardware effectively.

Explanation
