its memory.
Memory cache stores frequently used instructions and data on a computer. Cache memory is stored on a memory chip in an area of the RAM.
ROM (Read Only Memory) stores the information currently being used by the computer. It holds all your loaded programs, and the data that goes along with them, waiting for the processor to make use of the information (to process it, if you will). RAM (Random Access Memory) is memory which cannot be changed. This would be information hard-wired into your electronic device. For a computer, this might be the default BIOS and BIOS settings.
The ROM BIOS chip stores permanent instructions. ROM means read-only memory. BIOS means basic input/output system, meaning the very basic instructions needed to power up the computer. From there, the operating system loads.
Both the processor, which allows the computer to do tasks, the better that is, the faster your computer can work the RAM which stores the things for the processor to process, the more you have the better. AND the hard drive, the faster this is, the faster the processor can grab information off it.
Hmmm, a CPU (processor) stores no data. RAM or Memory can store data as long as the computer is ON and the Hard Drive can store data indefinately (forever).
