What is a virtual Machine💾📀🖥️(VM)
A Virtual Machine (VM) is a compute resource that uses software instead of a physical computer to run programs and deploy apps.
Think of it like computer inception. Running a computer within a computer, by emulating it's hardware and software components.
Here I have an instance of Kali Linux running in KVM using QEMU and VMM.

There are many tools available to accomplish this, some of the free and most well known ones are:
All you need to get started is one of the above applications and an ISO image of your chosen operating system.
After that it's up to you to set a goal for what task you want your VM to do.
That's where - My Projects and Studying Materials🔬 comes in handy.
I will add another page covering Docker and containerisation.
