What does ERC mean?

ERC... hmm, what exactly does it stand for? I'm curious about this acronym as it seems to be quite prevalent in the cryptocurrency sphere. Could it be related to a specific blockchain protocol or perhaps a token standard? I've heard it mentioned in conversations about Ethereum, but I'm not entirely sure of its significance. Could you please elaborate on ERC and its role in the crypto ecosystem? I'm eager to learn more about this topic.
