Virtual Machine Definition & Importance

While I have research or something (testing) doing in my operating system, that time I want some prevent actions, so I am using this Virtual machine to testing my research. Virtual machine is nothing but, run other operating system in your host operating system. This is the major thing of your operating system. 

Why virtual machine

• Isolation from your host operating system (multiple os environment)
• Easy to start and stop
• No need any other maintenance.

Disadvantage:

• It will run indirectly access to your host operating system. So your host operating system performance will be decreased. Sometimes it will unstable (Don’t worry).
• Isolation from host operating system
• This will run multiple operating system environments, so it’s strongly isolation from each other. So if you’re are running or test some software, it will never hurt you host operating system. For example if you’re testing potentially unstable software, this is the right method to use your research.

Easy to start and stop

This isn’t a dual boot method. It will run by a third party program. So it’s easy to start and stop. In case you are using dual boot method, then how to switch to other operating system. This is not possible for without restart your pc. So in the virtual machine, you also switch to host operating system and guest operating system without any failure and risk. One can start the virtual machine in same state; it was in when it was stopped.

Quick recovery

In most case you are getting any unstable condition, VM having snapshot function. It will help you for when you want. So this is always save your Time.
