Why is ROM needed in a computer?

Answer 1

First off ROM stands for Read Only Memory. ROM is important to the computer's functionality because it retains all of the data even if the computer is powered off. ROM is usually what is used to store the data in order to even boot up a computer.

Answer 2

Technically speaking, you don't - ROM (read-only memory) is just a convenient way to store computer instructions and data which persist (won't disappear) when power is removed from the system (i.e., it's a type of non-volatile memory).

There are other ways to address the situation, but in the world of PCs-workalikes, it's a common way to store the programs & data used to bootstrap the PC so it runs initial tests, sets all the hardware and critical volatile memory locations to a "known" condition, and loads the operating system. Typically these days, though, the ROM in a PC is more likely to be an EEPROM - an electrically erasable programmable read-only memory - to permit changes in the field (e.g. updates).

Answer 3

The ROM chip - is a semi-permanent piece of memory. It' kick-starts the computer's boot system so that it loads all necessary drivers and 'start-up' programs to RAM when the machine is switched on. RAM is only temporary storage space - it loses its contents when the power is switched off.

Answer 4

The Read Only Memory (ROM) is a chip on the motherboard that the manufacturer of the computer has burnt in specific instructions. The ROM carries code that is not designed for the user to alter or interfer with. The ROM is there to give instructions to what the computer should do next in order to make the computer ready for the user to 'use'.

Answer 5

it is needed because ROM and RAM is what makes up the hard-drive and without the ROM the computer would not be able to start.
