Main Memory is referred as Computer memory or hard disk, While RAM is basically standing for Random Access Memory. As it name shows that it is to be accessed randomly.
Availability of data in RAM is random; it means that data keep changing with the requirement of the CPU. RAM is used as "Working memory" storage area within the computer.
Hard drive stores data on the computer, but if the CPU has to process on data that is stored in a computer. Then CPU Uses ram, data from hard drive is fetched to ram chips. The CPU doesn’t access the data directly from the hard disk.
You can add more RAM to your computer; It will reduce the number of times your CPU to read data from hard disk. This usually will enhance the speed of your computer and allows it to work faster.
Because accessing the data from RAM is much faster than a hard drive. When you turn on the computer, it boots firmware (BIOS).Â
It Loads instructions in RAM which is stored in semi-permanently ROM chips. That instruction describes the information and configuration related to computer.
Similarly if there is no RAM in the computer, the computer will be unable to load the file and thus it will not perform any task at all.

Memory is a device that we used in storing data and programs. We have RAM, ROM, Cache, Memory sticks, Flash Memory, Virtual Memory, Dynamic and Static RAM and more.
When we say memory, it pertains to a data storage that comes in the form of a electromagnetic ships that can hold data. It often refers as a physical memory. We also used virtual memory that inflates the physical memory on a hard disk.Â
