The correct answer is: D. Memory
Memory is the hardware in which data may be stored for a computer system. It is a temporary storage area where data is held while it is being processed by the computer. Memory is divided into two main types: RAM (random access memory) and ROM (read-only memory). RAM is a volatile memory, which means that it loses its contents when the power is turned off. ROM is a non-volatile memory, which means that it retains its contents even when the power is turned off.
