FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -In computing, a virtual machine (VM) is the virtualization/emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination.

Detailed explanation-2: -In emulation, you use full hardware and software that you want to imitate on top of the host system. In virtualization, you mimic the only parts of the hardware according to your requirements with the help of guest OS to run correctly to have the same architecture.

Detailed explanation-3: -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-4: -A virtual machine (VM) is a virtual environment that functions as a virtual computer system with its own CPU, memory, network interface, and storage, created on a physical hardware system (located off-or on-premises).
