There are two types of memory in a computer - volatile and non-volatile. Volatile memory is the Random Access Memory (RAM) which is lost after the power is cut. The non-volatile memory is the hard drive which permanently writes information (binary code) to metal platers using magnet charges. After the computer is powered off, the magnetic charges do not change.
