The RAM and ROM are two kinds of memory that exist in a computer. The ROM stands for Read-only Memory while the RAM stands for Random -access Memory.
The RAM serves as the temporary memory of the computer. Every application that you open on your computer runs on RAM. Once you close the app, it is removed from RAM.
On the other hand, ROM serves as the storage unit of your computer or device. This is where all of the files in your computer are stored like your music file, favorite photos, ebooks, and more. Examples of ROM that you commonly know are the hard drives (both internal and external), flash drives, and memory cards.
Let's put it into a situation. You want to work on your assignment, so you open a word processing software. Once the word processing software opens, it runs on RAM. Everything that you do on it before you save it is stored in the RAM. However, if you are done and you decide to save your work, that file is stored in the ROM.
