What is the meaning of ERC?

Could you please clarify the significance of ERC for me? I've encountered this term quite frequently in the realm of cryptocurrency and finance, but its exact meaning remains elusive to me. Is ERC associated with a specific type of blockchain technology? Or perhaps it refers to a certain standard or protocol within the crypto ecosystem? Additionally, how does ERC fit into the broader context of cryptocurrency and finance? I'm eager to gain a deeper understanding of this term and its relevance in today's digital economy.
