Answer to Question 1

Three types of virtualization exist: PC virtualization, server virtualization, and desktop virtualization.
With PC virtualization, a personal computer, such as a desktop or portable computer, hosts several different operating systems. Say a user needs to have both Windows 8 and Linux running on his or her computer. In that circumstance, the user can install a virtual host operating system and then install both Windows 8 and Linux on top of it. In that way, the user can have both systems on the same hardware. VMWare Workstation is a popular PC virtualization product that can run both Windows and Linux operating systems.
With server virtualization, a server computer hosts one or more other server computers. In a Windows Server computer hosting two virtual machines, users can log onto either of those virtual machines and they will appear as normal servers. Server virtualization plays a key role for cloud vendors.
PC virtualization is interesting and sometimes quite useful and server virtualization is key to cloud economics. Desktop virtualization, on the other hand, has the potential to be revolutionary. With desktop virtualization, a server hosts many versions of desktop operating systems. Each of those desktops has a complete user environment and appears to the user to be just another PC. However, the desktop can be accessed from any computer to which the user has access. Thus, the user could be at an airport and go to an airport computer and access his or her virtualized desktop. To the user, the airport computer appears as his or her own personal computer. Later, the user could do the same to a utility computer sitting in a hotel room. Meanwhile, many other users could have accessed the computer in the airport, and each thought he or she had his or her personal computer.
