What Are Virtual Machines?
A virtual machine is like a physical computer but it is actually a digital version of it. Actually, it is not so much different from physical computers because they have also memory, CPU, as well as they have disks to store our data or various files and one more interesting thing is that they can also connect to the internet. So we can say that a VM is actually the software-defined computer that exists only as a code but is present on physical servers.
