Which characteristic describes EPROM?

• A. A chip that is volatile and requires power to maintain data
• B. A chip that is nonvolatile and can be erased by exposing it to strong ultraviolet light
• C. A memory type that cannot be erased once written
• D. A fast-access temporary storage type

Answer: (B)

EPROM, or Erasable Programmable Read-Only Memory, is defined by its nonvolatile characteristic, meaning it retains stored data even when power is removed. The specific attribute that sets it apart is the ability to be erased by exposure to strong ultraviolet light. This feature enables EPROM to be reprogrammed, making it a flexible option for applications requiring data updates or corrections. This method of erasure is notable because it differs from other types of memory that either lose their data without power or cannot be altered once written. Understanding this allows for a clearer distinction between various types of memory technologies, such as volatile and nonvolatile memories, which operate under different principles of data storage and retention.
