Historically, each computer has its own operating system, applications, and dedicated hardware components. Now, using software emulation, several virtual computers can run on a single physical computer. This means each virtual computer has its own operating system, applications, and dedicated hardware components. This is known as virtualisation in computing. Each virtual machine, shown in the figure, operates independently.
In the corporate world, a single physical infrastructure can run multiple virtual infrastructures. By virtualising the servers and networks, companies can reduce operational and administrative costs. The operational savings can come from the reduction in power and cooling requirements and the number of physical machines. A virtual server can be added to support additional applications.
You can also use virtualisation for your personal computing needs. You can try a new operating system on your computer without damaging your current system. You can browse the internet safely with your virtual machine. The virtual machine can be deleted if anything goes wrong.
