Explain types of primary memory storage.
RAM: It stands for Random Access Memory. RAM is known as read/write memory. It is the main memory of the computer system. The information stored in this memory is lost as the power supply to the computer is switched off, so it is also called as "Volatile Memory.”
ROM: It stands for Read Only Memory. ROM is permanent memory. The content is not lost when power supply is switched off. ROM cannot be overwritten by the computer, so it is also called ”Non-Volatile Memory”,
