The hypervisor which works on older PC's without hardware virtualization support is called VirtualBox. It is a software allows you to run operating systems in special environment which is called virtual machine. It means that you can run another OS without re-installing existing one.
Virtual memory frees up RAM by transferring data that hasn't recently been used to a storage device, such as a hard disk or solid-state drive (SSD). Virtual memory is useful for multitasking, running large programs, and speeding up the system.
<h3>
What is the role of virtual memory in disk storage space?</h3>
Virtual memory fulfills two functions. First, by using disk, it enables us to increase the utilization of physical memory. Because each virtual address is converted to a physical address, it also enables memory protection.
An operating system may load programs larger than its physical memory thanks to virtual memory, which is its fundamental benefit. The users get the idea that the machine has boundless memory. Additionally, it offers memory security.
Therefore, operating systems move code and data, as necessary, to a portion of the disk that is used as if it were memory, not just disk storage space.

Answer:
How to convert binary to decimal ?
It consists of digits from 0 to 9. Binary to decimal conversion can be done in the simplest way by adding the products of each binary digit with its weight (which is of the form - binary digit × 2 raised to a power of the position of the digit) starting from the right-most digit which has a weight of 20.
what is digital and analogue?
In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape.In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device.
