Quick Answer: What Is The Different Between RAM And ROM?

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..

Which is bigger RAM or ROM?

A ROM chip stores several MB (megabytes) of data, usually 4 to 8 MB per chip, whereas a RAM chip can store multiple GB (gigabytes) of data, ranging from 1 to 256 GB per chip.

What is ROM used for?

Short for read-only memory, ROM is a storage medium that is used with computers and other electronic devices. As the name indicates, data stored in ROM may only be read. It is either modified with extreme difficulty or not at all. ROM is mostly used for firmware updates.

What is ROM with example?
