What type of memory is referred to as 'volatile'?

• A. ROM
• B. Flash memory
• C. RAM
• D. Hard disk

Answer: (C)

Volatile memory is characterized by its ability to hold data only while power is supplied. Once the power is turned off, any data stored in this type of memory is lost. RAM (Random Access Memory) is the primary example of volatile memory, as it is used by computers to store data temporarily while programs are running. This means that whenever the system is powered down or restarted, all information held in RAM is erased. In contrast, other types of memory such as ROM (Read-Only Memory), Flash memory, and hard disks retain data even when the power is off. ROM is used primarily to hold firmware, while Flash memory is often utilized in storage devices such as USB drives and SSDs. Hard disks serve as long-term storage for large amounts of data. Therefore, RAM is specifically noted as volatile memory due to its temporary data retention only during active use.
