RAM + ROM
All about RAM & ROM, what they do and how they are used.
What Are They?
RAM, unlike ROM, is considered to be "volatile" (its stored information is lost if power is removed) and as such is used for temporarily storing data of operating programs when they are not saved, like a short term memory. When you save a file the computer saves it to a hard disk which is akin to a long term memory.
More about RAM and ROM
There are many types of ROM including EPROM, EEPROM, EAROM and PROM, which all allow for varying amounts of rewritability. A cross between RAM & ROM is Flash Memory which allows for data to persist without power yet still be rewritable.
