Answer:
There is one major difference between a ROM (read-only memory) and a RAM (random-access memory) chip: ROM can hold data without power and RAM cannot. Essentially, ROM is meant for permanent storage, and RAM is for temporary storage.
A ROM chip is used primarily in the startup process of a computer, whereas a RAM chip is used in the normal operations of a computer once the operating system is loaded.
A RAM chip can store multiple GB (gigabytes) of data, ranging from 1 to 256 GB per chip. A ROM chip stores several MB (megabytes) of data, usually 4 to 8 MB per chip.
