Answer:
RAM and ROM are both types of computer memory. RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. ROM have prerecorded data and it is used to boot computer.
DIFFERENCE RAM ROM
Data retention RAM is a volatile memory which could store the data as long as the power is supplied. ROM is a non-volatile memory which could retain the data even when power is turned off.
Working type Data stored in RAM can be retrieved and altered. Data stored in ROM can only be read.
Use Used to store the data that has to be currently processed by CPU temporarily. It stores the instructions required during bootstrap of the computer.
Speed It is a high-speed memory. It is much slower than the RAM.
CPU Interaction The CPU can access the data stored on it. The CPU can not access the data stored on it unless the data is stored in RAM.
Size and Capacity Large size with higher capacity. Small size with less capacity.
Used as/in CPU Cache, Primary memory. Firmware, Micro-controllers
Accessibility The data stored is easily accessible The data stored is not as easily accessible as in RAM
Cost Costlier cheaper than RAM.
