RAM & ROM are the two major types of computer memory. ROM stands for Read-Only Memory. While RAM stands for Random Access Memory.
Unlike RAM, the Read-Only Memory cannot be directly accessed by the CPU. It plays an important role in the Booting Process. The info is first transferred to the RAM then CPU can access that data from the RAM.
Read-Only Memory may be a non-volatile memory. The info inside the Read-Only Memory retains albeit the facility of the CPU is transitioned.
What is ROM (Read-Only Memory)?
The capacity of ROM is relatively smaller than RAM. It’s slower and cheaper than RAM. The info in Read-Only Memory can only be read by a CPU. That’s why it’s said read-only. The info in Read-Only Memory can’t be modified.
What Does Read-Only Memory Do?
ROM stores “Firmware,” which is everlasting software that’s difficult-stressed out with integrated circuits. The producer suits a specially designed Read-Only Memory chip into a tool.
ROMs forward the instruction that a computer requires during bootstrapping. I feel that you guys must remember the BootStrapping process.
It may be a self-starting process where the essential software is loaded into the pc memory after power on or on a reset.
Unlike the non-unstable reminiscence of hard power, it’s tough and time-eating to rewrite a Read-Only Memory chip’s reminiscence.
In most cases, it’s impossible to adjust included circuits, which may additionally suggest you can’t update more primary forms of Read-Only Memory.
You’ll be capable of reprogramming a few cutting-edge sorts of Read-Only Memory, but best at sluggish speeds and with a special gadget.
