Why RAM is needed

RAM is needed when the software starts and while working. Because the speed of ROM is low, our computer can make the software work faster, so the computer needs RAM. Because the speed of RAM is very high, so our computer starts the software or application on RAM.

Due to which our software opens faster and works during this time RAM is used. As soon as we close the software, that data gets deleted from RAM but it gets saved in ROM. That's why RAM is very much needed to complete all these processes.
