Chapter 8: Client- Side Virtualization Flashcards
What is virtualization
The creation of an environment that seems real but isnt
What are the purposes of virtualization
virtual world, virtual classroom, virtualization, network virtualization, server virtualization, and desktop virtualization
What is client side virtualization
virtualization that occurs on the client side
what is server side virtualization
virtualization that occurs on the server side
what is VDI
virtual desktop infrastructure- the hosting and managing of multiple virtual desktops on network servers
what is a hypervisor
also called a virtual machine monitor ( VMM ), software that creates a virtual machine, providing access to the necessary hardware on the host machine in isolation from other virtual machines, and from a host operating system, if present
what is hardware assisted virtualization
required by most hypervisors, it enables efficient full virtualization using help from hardware
what is the difference between a hypervisor and an emulator
hypervisors must create a virtual machine compatible with that of the underlying machine, emulators allows you to run an OS or device on hardware with which it is completely incompatible. sometimes a virtual machine may emulate some piece of hardware in the virtual machine that is either nor present or not compatible in the underlying hardware.
emulators usually require more computing resources than hypervisors require for virtual machines
what is presentation virtualization
type of virtualization in which support for an app’s user interface and the user interface itself exists on a client computer, while the app itself runs on a server
what is application virtualization
type of virtualization where the entire app is virtualized and the user interface is not separated from the app, but is isolated in a VM
what is storage virtualization
type of virtualization that allows client computers to utilize many networked hard drives as though they are one drive or location
what is server virtualization
type of virtualization where a single machine hosts one or more server operating systems, each in a VM and each performing tasks independently from the other VM and from the host
what is a type I hypervisor
a hypervisor that does not require a host OS i.e. bare metal hypervisor
what is type II hypervisor
a hypervisor that does require a host OS i.e. virtual PC 2007, windows virtual PC
what is a host key
special key or combination of keys that will release the mouse and keyboard from control of the VM
