Which of the following is considered 'volatile' memory in a computer system?
ROM
Hard Disk
RAM
Flash Drive

Computer memory architecture classifies storage into primary memory (volatile RAM and non-volatile ROM) and secondary memory devices like hard disks and flash drives.
RAM stands for Random Access Memory and acts as the CPU's primary working workspace.
Volatile memory requires continuous power to maintain its stored data state.
Non-volatile memory like ROM and Hard Disks retain data even after power is completely removed.
Option A (ROM) is non-volatile memory used to store essential boot instructions like the BIOS.
Option B (Hard Disk) and Option D (Flash Drive) are non-volatile secondary storage devices.
RAM is divided into Dynamic RAM (DRAM), which needs constant refreshing, and Static RAM (SRAM).
C is correct тАФ RAM is classified as volatile memory because it loses its data when power is turned off.
Computer awareness questions in competitive exams frequently test differences between volatile and non-volatile memory components.
