Emulation is the process of simulating the hardware of one computer (particularly the processor) via software on a different one.

For instance, an emulator will let you use an arcade machine that no longer exist or use a game console that can no longer be purchased. Note that this section is different from Games: Video Games: Emulation because the focus here is on the emulation of personal computer systems and Operating Systems running on these.
