RAM / ROM

memory used by the programs running

programs use the memory to store info required to run the software

RAM stores instructions that are sent to the CPU to be decoded and executed

volatile memory is where the contents of it is erased when the power is turned of

DRAM - moving RAM that needs to be refreshed every 2 secs, most common

S-RAM - static RAM that does not need refreshing but uses more gates

ROM - read only memory, cannot be changed, on motherboard

BIOS - basic input/output system, makes sure all chips, hard drives, CPU functions and ports work together
