Kopec Explains Software

Emulators allow software designed for one computing system to run on another. They act as a kind of translation layer, simulating the hardware of the emulated system in software. Common applications include running software designed for video game systems on personal computers, and running business applications designed for a computing platform that the user doesn’t own. We discuss what emulators do, how they work, and some of the legal issues around them in this episode. Follow us on Twitter @KopecExplains.
