Server Virtualization
Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments. The virtual environments are sometimes called virtual private servers, but they are also known as guests, instances, containers or emulations.
There are three popul...

Storage Virtualization Definition
Storage Virtualization Definition
Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.
Storage virtualization helps the storage administrator perform the tasks of backup, archiving, and recovery more easily -- and in less time -- by disguising the actual complexity of a storage area network (SAN). Administrators can implement virtualization with software app...

Network Virtualization
Network Virtualization
Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. Each channel is independently secured. Every subscriber has shared access to all the resources on the network from a single computer.
Network management can be a tedious and time-consuming...

Virtualization Meaning
Virtualization Meaning: In computing, virtualization means to create a virtual version of a device or resource, such as a server, storage device, network or even an operating system where the framework divides the resource into one or more execution environments. Even something as simple as partitioning a hard drive is considered virtualization because you take one drive and partition it to create two separate hard drives. Devices, applications and human users are abl...

Virtualization Definition
Virtualization is the creation of a virtual -- rather than actual -- version of something, such as an operating system, a server, a storage device or network resources.
You probably know a little about virtualization if you have ever divided your hard drive into different partitions. A partition is the logical division of a hard disk drive to create, in effect, two separate hard drives.

guest OS (guest operating system)
A guest OS is the software installed on either a virtual machine (VM) or partitioned disk that describes an operating system that is different than the host operating system.
Virtualization technology allows a computer to run more than a single OS at the same time. A guest OS on a virtual machine can be different from the host OS while a guest OS on a partitioned disk must be the same be the same as the host OS. For example, if the host OS is running Windows...
