Hides the complexities of the hardware from the user
|
Detailed explanation-1: -Answer. Explanation: The Virtual Machine is presented by the Operating System to the user, hiding all the complexities of the hardware behind layers of OS software.
Detailed explanation-2: -Abstraction leads to simplicity Users and applications do not see the hardware directly, but view it through the OS. This is used to hide certain hardware details from users and applications (called abstraction). Due to this abstraction, users cannot see changes in the hardware.
Detailed explanation-3: -Hardware virtualization, sometimes called platform or server virtualization, is executed on a particular hardware platform by host software. Essentially, it hides the physical hardware. The host software that is actually a control program is called a hypervisor.
Detailed explanation-4: -A virtual machine (VM) is an operating system (OS) or application environment that is installed on software, which imitates dedicated hardware. The end user has the same experience on a VM as they would on dedicated hardware.
