What is the difference between ETH and ERC20 address?

Could you please elaborate on the distinction between ETH and ERC20 addresses? As I understand, both play significant roles in the blockchain ecosystem, but I'm curious about their specific differences. For instance, how do they function differently when it comes to transactions and interactions with the blockchain? Additionally, is there a specific use case where one might be preferred over the other? I'm eager to gain a deeper understanding of these two addresses and how they fit into the broader cryptocurrency landscape.
