Virtual Machine


 Introduction

Some people may think that this technology is recent as a result of the great development that we see every day in computers or the hardware that composes them. The truth is that at all because the beginnings of this technology are very old and go back to the year 1960 and the first to develop it was IBM or International Business Machines, as it is known. Computers in that era, especially the IBM 7044 (M44), were performing one processing at a time, which negatively affected the ability of processors to work, especially since the development of processor power was not difficult, which was the reason for the birth of the virtualization technology that allowed the use of processor power By several people by dividing it into several fake devices that are controlled through dedicated devices or Client and thus allowed them to run more than one application at the same time,This technology faced many problems at the time, such as not enabling customers to run untrusted unsafe programs because their performance could negatively affect the kernel in general in addition to the inability of each client to perform any update or upgrade process for his system and finally there was no possibility to control the hardware division Fairly between clients.


What is meant by default or with machine the Virtual Machine ?

The Virtual Machine is a file that works like any other program, but differs from the rest of the other programs in that it works as a standalone computer! But how?


 A virtual machine allows another operating system to run on the same machine. In other words, it provides the possibility of a computer inside a computer, by acting as a window for any other program. The Virtual Machine works to give the user an integrated environment for a specific operating system identical to the use of any other computer. Thus, the user can use two operating systems on one computer. It also allows the possibility of using one computer by more than one user, as each user works on an operating system and programs different from the others.


For example: you are using the Mac OS and at the same time you are working on Windows 7 or Windows 10.
