Read-only memory

Read-only memory or ROM is like a book that has been already written and cannot be changed. Let's pretend that this book tells a story about your favorite cartoon character. You can read it and follow along with the story, but you can't change anything in the book or make the character do something else.

In the same way, ROM is a type of computer memory where information is stored and cannot be modified or deleted. This memory is usually built into devices, like your computer or your phone, and it stores important information that the device needs to function properly.

For example, your computer's ROM might have the instructions for how to start up when you turn it on. This is like the first chapter in your favorite cartoon book that you always start with. It's set in stone and cannot be changed.

Unlike other types of computer memory, like RAM, where you can add or delete information, ROM is permanent and cannot be changed. So, if you are thinking of writing on this book, sorry, but you can't change what is in there.
