Techopedia Explains Legacy Device

Typically, a legacy device consists of non plug-and-play (PnP) devices that lack a peripheral controller interface (PCI) and requires manual configuration and jumper installation. A legacy device also includes computing equipment rendered obsolete by modern technologies.

For example, because CD drives replaced floppy disk drives, there are few new computers distributed with built-in floppy drives. Similarly, native legacy devices are not supported by most modern software applications.
