FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Virtualization relies on software to simulate hardware functionality and create a virtual computer system. This enables IT organizations to run more than one virtual system – and multiple operating systems and applications – on a single server. The resulting benefits include economies of scale and greater efficiency.

Detailed explanation-2: -Service virtualization is the process of creating replicas of systems that new applications depend on to test how well the application and systems integrate.

Detailed explanation-3: -Hardware virtualization is the method used to create virtual versions of physical desktops and operating systems. It uses a virtual machine manager (VMM) called a hypervisor to provide abstracted hardware to multiple guest operating systems, which can then share the physical hardware resources more efficiently.

Detailed explanation-4: -Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer-processors, memory, storage and more-to be divided into multiple virtual computers, commonly called virtual machines (VMs).
