Virtual machines

1.24K views

I’m trying to understand them a bit better, but it’s just not clicking for me. How is it able to operate like a physical computer and what is the benefit of that? Would you be able to say write an essay for your English class on a VM, save it there, and access it at a later time?

A VM is just a program that pretends to be a computer. Where a physical computer has transistors and hard drives, a VM is programmed to simulate those. As far as the software running on a VM is concerned it’s running on a physical computer. The program just says “I want to save a document to the hard drive,” and the VM takes that document as saves it to a file on the actual machine.

It allows us to do some cool things like:

* Run multiple different machines off 1 physical computer (just like you might run Chrome and a video game at the same time)
* Quarantine users to a virtual space that makes it hard for them to mess with anything. EX: A student can’t log into their schools network at 1:00 in the morning and mess around with things they aren’t supposed to. Since it’s a VM if anything got messed with they would just delete the VM and create a new one, no different than deleting a Word doc.
