There are critical differences between virtualization and emulation that demand particular attention. Virtualization is a method of splitting a single physical device into several environments (Taylor, n.d.). Emulation is a way to execute processes for one type of a system within another one with a different architecture (Taylor, n.d.). This research paper will discuss what differences exist between these two concepts and their importance.

Virtualization and emulation may often be mistaken by a regular user, although they are fundamentally distinct. Virtual machines possess the code that is sufficient to run on a computer, while an emulator uses an interpreter to converse with the already running operating system (Taylor, n.d.). Virtualization accesses the systems hardware resources directly, creating the potential for optimization (Hammad, 2021). In turn, emulation is much slower than virtualization since it translates its actions first (Hammad, 2021). The significant advantage of emulation is its cost efficiency, as virtual machines are often more demanding (Taylor, n.d.). Their usage differs since virtualization is usually implemented to increase the workload efficiency, while emulation is deployed when the product must be used or tested within a different environment (Hammad, 2021). Understanding these concepts makes it easier for a developer to assess the necessary resources for work adequately. Virtualization can take the form of several instances of an operating system on a machine, while emulation can be presented as software that behaves in a way the real machine with the desired specifics would.

In conclusion, virtualization and emulation are two different processes that are defined by their usage of the systems resources, cost-efficiency, their role in testing environments, and the general purpose. Machines that run virtualizations have these systems installed directly and use more resources, while emulation is deployed upon the existing structure, making it easier to manipulate. They can serve as testing environments, but each has its specific application.
