Volatile Memory Definition
Volatile memory is computer memory that requires power to maintain the stored information. If the power is turned off, the data stored in volatile memory is lost.
Memory Type Analysis
Let's examine each option to determine which is volatile:
- RAM (Random Access Memory): RAM is the primary working memory in computers. It requires continuous power to hold data. When the power is cut, RAM loses its contents, making it volatile.
- EPROM (Erasable Programmable Read-Only Memory): EPROM is a type of non-volatile memory. It retains data even when not powered.
- ROM (Read-Only Memory): ROM is non-volatile memory. The data stored in ROM persists even after the power is removed.
- PROM (Programmable Read-Only Memory): PROM is also non-volatile memory. It stores data permanently after being programmed.
Identifying Volatile Memory
Comparing the options against the definition of volatile memory, only RAM fits the description.
