Explanation:
1. Random Access Memory (RAM) –
It is also called read-write memory or the main memory or the primary memory.
The programs and data that the CPU requires during the execution of a program are stored in this memory.
It is a volatile memory as the data lost when the power is turned off.
RAM is further classified into two types- SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory).
2. Read Only Memory (ROM) –
Stores crucial information essential to operate the system, like the program essential to boot the computer.
It is not volatile.
Always retains its data.
Used in embedded systems or where the programming needs no change.
Used in calculators and peripheral devices.
ROM is further classified into 4 types- MROM, PROM, EPROM, and EEPROM
