Before you find yourself on this page, I believe you know what RAM (Random Access Memory) is used for in any computing device (A computer, to be precise).

According to Wikipedia,

Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code.

In summary, the RAM is needed to enjoy super-fast computation since it is used as a short-term memory storage space for the computer to place data it’s currently working on for easy accessibility.

On a PC, there are two types of RAM: Physical RAM and Virtual RAM, both used for memory management.

Physical RAM is the memory that holds applications, documents, and procedures on a computer (More RAM, More Speed).

Virtual Memory, on the other hand, is a memory management technique that allows data in RAM that is not currently in use to be transferred to the hard disk, making space available in RAM for other programs.

Virtual memory holds the files on your hard drive for easy retrieval when a computer runs out of physical RAM.
