To prevent software from being used on other devices, people prefer to use non-standars instruction sets. But there are still a few different 'instruction sets'. As an example, a program written for a CPU made by A will not run on a CPU made by B. The problem is that their CPU understood their proprietary instructions. I'm glad you asked! To answer this question, I'll need to explain something else: compiling.Ī long time ago, back when computers were less powerful than a calculator, a lot of different companies tried to make their CPU (a CPU is the part of the computer that executes instructions). Why don't we just run the software from the PS2 on the PC? This window is a 'virtual' or 'fake' screen that is connected to a 'fake' playstation 2. There will be a window on your desktop, just like your web browser. The Playstation 2 that will run as another software will be called the guest.Īn emulator typically enables the host system to run software or use peripheral devices designed for the guest system. To behave like another computer system (called the guest) There are two states you can be in right now: You're either even more confused, or trying to figure out how this is useful.Īn emulator is hardware or software that enables one computer system (called the host)

An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. In computing, an emulator is hardware or software that enables one computer system (called the host) to behave like another computer system (called the guest). Since this is the basics of what we're about to do, let's take a while and explain what it is. 'emulation' You've been hearing this for ages (maybe) but you don't know what it is.
