In this post, we will understand the difference between RAM and ROM memory −
It is known as Random Access Memory.
It is a volatile memory that can store data as long as power is being supplied.
The data stored over RAM can be retrieved and changed.
It is used to store data that needs to be currently processed by CPU (temporary).
It has a high-speed memory.
The CPU can access the data stored on a RAM.
It is large in size and comes with a higher capacity.
It can be used as CPU cache, and as primary memory.
The data stored on a RAM can be accessed easily.
It is expensive.
It refers to Read Only Memory.
It is a non-volatile memory which can retain the data after the power is turned off.
The data stored in a ROM can be read only, not written to.
It stores the instructions that would be required during the bootstrapping of the computer.
It is slower in comparison to RAM.
The CPU can’t access the data stored in ROM.
It is small in size.
It has less capacity.
It can be used firmware and micro-controllers.
The data stored on ROM can’t be accessed as easily as in RAM.
It is less expensive in comparison to RAM.
