Q #2) Are virtual machines legal?

Answer: Using a virtual machine is legal if you own a licensed operating system. You must also have the license for the software that you want to test in a virtual environment.

Q #3) What are the uses of a virtual machine tool?

Answer: Virtual machine apps have different uses. Developers use the application to test new software in a controlled environment. They can change the variables to test the app in different virtual environments.

In addition, network security personnel test software in a virtual environment before deployment. VMs also result in reduced overheads as it allows companies to use different operating systems without having to purchase additional hardware.

Q #4) How does a virtual machine work?

Answer: A virtual machine application runs in an isolated environment with its isolated power, CPU, memory, operating system, and other resources.

Q #5) Are virtual machines slower than native systems?

Answer: Virtual machine apps create a virtualized environment on top of an existing operating system. The virtual environment uses more CPU load and physical memory due to which VM apps can be 5 to 100 percent slower than native systems.
