Emulation and virtualization are two different technologies which, having points in common and being able to be used to achieve the same goal, present substantial differences . 

Often, in fact, emulation and virtualization are terms used in an alternative way, almost as if they were synonyms. However, things are not like this. 

These two technologies share a common goal: to create a virtual environment capable of running an operating system or application, bypassing software and hardware limitations that can prevent proper execution.

Emulation is a very widespread and versatile system but with very specific limitations, especially in terms of performance. Virtualization, on the other hand, allows you to solve some emulation problems by guaranteeing users the ability to complete various tasks in a simple and safe way. 

So let ‘s see what is meant by emulation and what by virtualization and what are the differences between these two procedures.

Difference between the host system and guest system to better understand emulation and virtualization

In order to analyze, in detail, the differences between emulation and virtualization, it is appropriate to establish, first of all, some very important basic concepts. 

In particular, it is necessary to define the concept of host system or host system which must be accompanied by the guest system or hosted system .
