In windows 8.1 which of the following options in control panel is related to adjustment of display brightness, volume and power options ?

Question

Accepted Answer

The correct option is (1):
The **Windows Mobility Center** is a specialized utility in the Control Panel, designed explicitly for laptop and mobile device users in Windows 8.1. Its primary design goal is to provide a single, centralized dashboard for managing the most common and frequently adjusted mobile settings. These settings invariably include controls for hardware features vital to mobile usage, such as an adjustable slider for the **Display Brightness** and a master control for **Volume**. Crucially, it also features a tile that links directly to the detailed **Power Options**, allowing for quick switching between different power plans like Balanced or Power Saver, making it the definitive answer for the question's requirements.

The incorrect option is (2):
The **Sync Center** is a feature focused purely on file management and data consistency, specifically dealing with Offline Files. Its role is to help users synchronize copies of files between their computer and network folders so they can work on them even when disconnected from the network. It reports on the status of these synchronizations and allows users to manage them. The Sync Center holds no controls related to the physical hardware adjustments like brightness, volume, or power scheme selection.

The incorrect option is (3):
The **Action Center** serves as a notification hub and is the primary location for system alerts and recommended maintenance tasks. It aggregates warnings about security issues, such as an out-of-date firewall or antivirus, and maintenance needs like backups or disk errors. Its function is to inform the user about system health and necessary actions. However, it is not a configuration tool and therefore does not contain any direct controls, such as sliders, for modifying display brightness or system volume levels.

The incorrect option is (4):
The **Device Manager** is an administrative tool used for managing the physical hardware components installed on the system. Users employ it to view the status of devices (like the display adapter, sound card, and battery), install, update, or roll back drivers, and troubleshoot hardware conflicts. While it lists the devices that control brightness and volume, it is not the user-facing utility for making routine adjustments to these settings, nor does it typically offer the interface for managing power schemes.
