computer
No computer has more authority than another

Name three qualities of Client Server Architecture:

responds accordingly

How is change control applied in virtualization?

Should be tested in staging environment to ensure no impact to host of guest operating system. (any changes to hardware/software will go through a change control board and then tested in a staged environment)
