Which of the following statements about onboard devices is true?

Onboard devices are components that are integrated directly into the motherboard of a computer. This integration allows for better space management and typically ensures that these devices operate more efficiently since they are designed to work seamlessly with the other components of the system.

The nature of onboard devices means they often include essential components such as the network interface controller, sound card, and various storage connectors. By being part of the motherboard, these devices benefit from direct communication pathways and shared resources that enhance overall system performance.

In contrast, the other statements do not correctly describe onboard devices. For instance, onboard devices do not always require additional installation, as they are ready to use as soon as you set up your computer. Also, while they typically cannot be upgraded in the same manner as discrete components, this statement overlooks the fact that some systems allow for additional features to be added or replaced. Lastly, the assertion that onboard devices are external contradicts the very definition of what makes a device "onboard," as external devices are, by nature, separate from the motherboard.
