Emulation refers to the process of imitating the behavior of one computer system or electronic device using another computer system or electronic device. In other words, it's the ability of a system (the emulator) to behave like another system (the emulated system), often for the purpose of running software or applications designed for the emulated system.

"Emulation can be used for various purposes, such as:\n\n1. Running software or games designed for older systems on modern hardware.\n2. Testing software in a simulated environment before deploying it on real hardware.\n3. Developing and debugging software for different platforms.\n4. Preserving and accessing legacy software and systems.\n"
