Concept:
RAM and ROM are two types of primary memory used in a computer system. Both are essential for storing data, but they differ in purpose, behavior, and functionality.
RAM (Random Access Memory):
RAM is a volatile memory that temporarily stores data and programs currently in use by the computer. The data in RAM is lost when the power is turned off.
Features of RAM:
Temporary storage
Fast read and write operations
Volatile (data lost when power is off)
Used while running applications
Examples: DDR4 RAM, DDR5 RAM
ROM (Read Only Memory):
ROM is a non-volatile memory that permanently stores important instructions required to start the computer. The data remains even when the power is turned off.
Features of ROM:
Permanent storage
Mostly read-only
Non-volatile (data retained without power)
Stores firmware like BIOS
Examples: BIOS chip, Firmware memory
