When it comes to RAM (Random Access Memory), think of it like your brains notepad. It temporary stores everything your computer is actively using right now at this second. When you turn off your computer, basically the RAM is erased. Primarily, RAM is used for running programs, opening files browsing the web and so forth. Ultimately, it can be fast, but temporary. An example for this can be as if you open up a game, it loads into RAM so it runs quickly. But when you shut it down the computer, its gone from RAM. Moving on to ROM (Read-Only-Memory), in which is like your brains basic instincts. It stores important instructions that your computer needs to start up, like the BIOS or firmware. You can’t easily change what’s in ROM (at least not without special tools), and it remains there even when you turn the power computer off.
