When a user enters data using input devices, the computer system stores this data in a memory unit i.e. storage unit. The storage unit uses a set of pre-programmed instructions to further transmit this data to other parts of the CPU. There are two types of memory
- Primary Memory
- Secondary Memory
RAM: It stands for Random Access Memory. RAM is known as reading/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 the power supply is switched off. ROM cannot be overwritten by the computer, so it is also called “Non-Volatile Memory”.
