The Building Blocks of Virtualization
To virtualize a guest operating system with your current PC and operating system as host, you need two software components:
- A virtualization program that supports your current operating system as a host
- A guest operating system that is supported by the virtualization program
In some cases, you might not need to pay anything for either component, which is a boon if you're trying to prepare for the CompTIA A+ Certification exams without spending a fortune on additional software or hardware.
