What device is typically not categorized as plug-and-play?

The typical characteristics of plug-and-play devices involve their ability to be connected to a computer system without requiring extensive user intervention to install drivers or software. Devices that are plug-and-play are generally recognized by the operating system as soon as they are connected.

The old external hard drive is often not categorized as plug-and-play due to its reliance on specific drivers or setup processes that may not be automatically recognized by more current operating systems. Many older external hard drives require manual installation of drivers or configuration, which means that when they are connected, the operating system may not correctly recognize them without additional user input.

In contrast, USB keyboards, digital cameras, and standard printers typically support plug-and-play functionality. These devices are generally designed to be user-friendly, allowing users to easily connect them and have the operating system recognize them with minimal hassle. This immediate recognition and usability make them standard examples of plug-and-play devices, distinguishing them from older external hard drives that may not have this seamless integration.
