Read MoreDifference between Virtualization and Hypervisor
Virtualization and hypervisor are closely related concepts in the field of computer science, specifically in the domain of system virtualization. While they are interconnected, they represent different aspects of the virtualization technology. What is Virtualization? Virtualization is a technique that allows the creation and operation of multiple virtual environments or virtual machines (VMs) on a single physical computer or server. It enables the sharing of hardware resources, such as processing power, memory, and storage, among multiple operating systems or applications. Each virtual machine functions as an independent and isolated entity, running its own operating system and applications. There are 4 ...
