The correct answer is: A. ROM
ROM stands for Read-Only Memory. It is a type of non-volatile memory that stores permanent data. This data can be read by the computer, but it cannot be changed. ROM is often used to store the BIOS, which is the basic input/output system that controls the computer’s hardware.
RAM stands for Random Access Memory. It is a type of volatile memory that stores data that is currently being used by the computer. This data can be changed or deleted at any time. RAM is much faster than ROM, but it loses its contents when the power is turned off.
LIFO stands for Last In, First Out. It is a type of data structure that stores data in a stack. The last piece of data that is added to the stack is the first piece of data that is removed. LIFO is often used in computer programs to keep track of the order in which events occur.
PROM stands for Programmable Read-Only Memory. It is a type of ROM that can be programmed once. Once the data has been programmed into PROM, it cannot be changed. PROM is often used to store firmware, which is software that is embedded in hardware.
None of the above is not a correct answer.
