Virtualization is a technique for hiding the physical characteristics of computing resources to simplify the way in which other systems, applications, or end users interact with those resources.

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 able to interact with the virtual resource as if it were a real single logical resource. The term virtualization has become somewhat of a buzzword, and as a result the term is now associated with a number of computing technologies including the following: storage virtualization: the amalgamation of multiple network storage devices into what appears to be a single storage unit. server virtualization: the partitioning a physical server into smaller virtual servers.

virtualization is a broad term that refers to the abstraction of computer resources. One useful definition is "a technique for hiding the physical characteristics of computing resources from the way in which other systems, applications, or end users interact with those resources. This includes making a single physical resource (such as a server, an operating system, an application, or storage device) appear to function as multiple logical resources; or it can include making multiple physical resources (such as storage devices or servers) appear as a single logical resource."[1] The term is an old one: it has been widely used since the 1960s, and has been applied to many different aspects and scopes of computing—from entire computer systems to individual capabilities or components. The common theme of all virtualization technologies is the hiding of technical detail, through encapsulation. Virtualization creates an external interface that hides an underlying implementation, e.g. by multiplexing access, by combining resources at different physical locations, or by simplifying a control system. Recent development of new virtualization platforms and technologies has refocused attention on this mature concept.

he ability to separate the physical layout of a network & its devices from how uses are organized into workgroups (knows a logical configuration).In computing, virtualization is a broad term that refers to the abstraction of computer resources.In storage, virtualization is a means by which multiple physical storage devices are viewed as a single logical unit.

Virtualization allows multiple operating system instances to run concurrently on a single computer; it is a means of separating hardware from a single operating system. Each “guest” OS is managed by a Virtual Machine Monitor (VMM), also known as a hypervisor. Because the virtualization system sits between the guest and the hardware, it can control the guests’ use of CPU, memory, and storage, even allowing a guest OS to migrate from one machine to another.

In storage, virtualization is a means by which multiple physical storage devices are viewed as a single logical unit. Virtualization can be accomplished in–band (in the data path) or out-of-band. Out–of–band virtualization does not compete for host resources, and can virtualize storage resources irrespective of whether they are DAS, NAS or SAN.
