Q22. What are Ram and ROM? How are there alike? How are they different?
Ans. Ram stands for Random Access Memory. The data is held in Ram, but temporarily the data disappears if the power is switched off. In other words, RAM is volatile memory.
ROM stands for read only memory. The data stored in ROM is not erased when the power is switched off I.e., it is permanent. ROM is a non volatile memory. This is held on chip inside the processor and is used to hold data that cannot be changed by the user.
RAM and ROM has one thing in similar i.e. both of them are hardware components in the motherboard .
