Exam 220-1101 topic 1 question 365 discussion

The first step that a technician should do is A. Reseat the webcam. Reseating the webcam means unplugging and plugging back the webcam into the laptop’s USB port. This can help to ensure that the webcam is properly connected and recognized by the laptop. Reseating the webcam is a simple and quick troubleshooting technique that can solve many common issues, such as loose or faulty connections, power or bandwidth problems, or driver or software conflicts. Reseating the webcam is the first step that a technician should do, because it follows the principle of starting with the easiest and most obvious solution before moving on to more complex and time-consuming ones. Reseating the webcam can also help to isolate the problem and eliminate other possible causes.

How can you reset a web cam when almost everyone are usb? plug it out and plug it in?

It says a laptop's external webcam Software and not a laptop's external webcam. I believe there is a difference.
