What’s the difference between a ROM and RAM chip?
A ROM chip is a non-volatile storage medium and does not require a constant source of power to retain the information stored on it. A RAM chip is volatile so it loses any information it is holding when the power is turned off. Test your knowledge of the basics of the two.
What does the ROM do on a computer?
ROM is a special kind of memory which stores the instructions which the computer uses when it ‘boots up’ – the BIOS (basic input output system). It allows it to check the type of hard disk installed, the amount of RAM installed (see next page), the type of CPU being used etc.
When does the Ram look first before the ROM?
