Question

64) What is virtualization and how and why is it used?
Short Answer:

Answer 1

Virtualization is the process of creating virtual versions of physical resources. It is used in server, desktop, and network environments to optimize resource utilization and enhance flexibility and efficiency.

Step-by-step explanation:

Virtualization is the process of creating a virtual version of a physical resource, such as a computer system, software, or network. It allows multiple virtual instances to run simultaneously on a single physical machine, thereby maximizing the utilization of resources and enabling greater flexibility and efficiency.

Virtualization is used in a variety of scenarios, including:

1. Server Virtualization: It enables multiple virtual servers to run on a single physical server, reducing hardware costs and improving scalability and manageability.
2. Desktop Virtualization: It allows users to access their desktop environment and applications remotely, increasing mobility and simplifying software administration.
3. Network Virtualization: It abstracts network resources, such as routers and switches, into virtual networks, enhancing flexibility and ease of management.

By consolidating resources and providing isolation between virtual instances, virtualization offers cost savings, improved performance, and increased agility in managing IT infrastructure.
