Write three differences of ROM and RAM.
Data-Retention RAM is a volatile memory that could store the data as long as the power is supplied.
ROM is a non-volatile memory that the could retain the data even when the power is turned off.
Read/Write Read and write operations are supported. Only read operations are supported. Use Used to store the data that has to be currently processed by CPU temporarily.
It is typically used to store firmware or microcode, which is used to initialize and control hardware components of the computer.
Speed It is a high-speed memory. It is much slower than the RAM.

Write definition of a virtual memory.
Virtual memory is a memory management technique that allows a computer to use hard disk space to simulate additional RAM, enabling it to run larger applications than the physical memory would normally allow. It creates the illusion of a large, continuous block of memory, helping to manage multiple processes efficiently.
