An Erasable Programmable Read-Only Memory (EPROM) retains its content until it is exposed to the 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. ultraviolet light

  • An Erasable Programmable Read-Only Memory (EPROM) retains its content until it is exposed to ultraviolet (UV) light.
  • EPROM is a type of non-volatile memory that can be programmed or written to, but its data can also be erased.
  • To erase the data stored in an EPROM, it needs to be exposed to ultraviolet light for a specified duration.
  • This UV light erases the data by resetting the memory cells, making the EPROM ready for reprogramming.
  • EPROMs were widely used in early computer and electronic devices for storing firmware and software that needed occasional updates or reconfiguration.
