What does EPROM stand for?

EPROM stands for Erasable Programmable Read-Only Memory. This type of memory is notable for its ability to be programmed and then erased through exposure to ultraviolet light, allowing it to be reused multiple times. Unlike standard ROM, which is typically hardwired with data that cannot be changed, EPROM offers flexibility in programming and allows for updates, making it valuable in applications where changes to stored data are necessary after the initial programming.

The key feature that defines EPROM is its reprogrammability, which distinguishes it from other types of read-only memory. This characteristic is particularly important in various electronics, especially in situations where firmware updates or changes in data need to be implemented without replacing the memory chip. Thus, the term "erasable" in the name highlights this capability, making option B the correct choice.
