Emulation, in computing, refers to the process of using hardware or software to enable one computer system to behave like another computer system. This allows the host system to run software or use peripheral devices designed for the guest system. Emulation is commonly used for various purposes, such as running an operating system on a hardware platform for which it was not originally engineered, running arcade or console-based games on desktop computers, and running legacy applications on devices other than the ones for which they were developed.
Emulation is also a strategy in pursuit of digital preservation and combating obsolescence. It focuses on recreating an original computer environment, which can be time-consuming and difficult to achieve, but valuable because of its ability to maintain a closer connection to the authenticity of the digital object, operating system, or even gaming platform. Emulation addresses the original hardware and software environment of the digital object and recreates it on a current machine. It is also commonly used during the design and development of new systems to detect, recreate, and repair flaws in the design before the system is actually built.
In addition to its computing context, the term "emulation" can also refer to ambition or endeavor to equal or excel others in achievement. This broader definition is not specific to computing and can be applied in various contexts beyond technology.
Overall, emulation plays a crucial role in the field of computing, enabling compatibility, preservation, and innovation in software and hardware systems.
