Can Computer Work Without ROM?

So, first of all, if you are asking what ROMs are –
they are the small programs that tell your computer how to function.
if you mean if a computer can function without any ROM at all –
no, computers need ROMs to know which operating system they are running. This is why if you remove both hard drives on your computer then it won’t be able to boot up into anything basically because both HDDs have operating systems installed on them. Computers need memory to function and that’s what the ROM provides for them. If there were no ROM present at all then it would just be a powerless machine with nothing stored in its memory whatsoever.
