Why is RAM faster?

RAM can be accessed hundreds of times times faster than a hard drive, which is why active programs are loaded into RAM. Since only small amounts of data from hard disk does need to be loaded into the system memory at one time, computers typically have much more hard disk space than memory.

Why is RAM faster than rom?

RAM is faster than ROM just because writing data to a ROM chip is a slow process, whereas writing data to a RAM chip is a faster process. A RAM chip can store multiple gigabytes (GB) of data, up to 16 GB or more per chip; A ROM chip typically stores only several megabytes (MB) of data, up to 4 MB or more per chip.

What is stored in ROM?

Read-only memory (ROM) is a type of storage medium that permanently stores data on personal computers (PCs) and other electronic devices.
