- Emulation is what we do when we try to make one system behave like or imitate a different system. We want to take System A (something we already have) and give it the inputs we would normally use for System B (which we may not have) and have System A produce the same results as System B.
- Virtualization is a technique for using computing resources and devices in a completely functional manner regardless of their physical layout or location. This includes splitting a single physical computer into multiple "virtual" servers, making it appear as though each virtual machine is running on its own dedicated hardware and allowing each to be rebooted independently.
