What does a bitcoin address look like?

Could you please elaborate on the appearance and structure of a Bitcoin address? I'm curious to know how these unique identifiers are formatted and if there's a specific pattern or set of characters that distinguish them from other types of cryptocurrency addresses. Understanding their visual representation would help me gain a clearer grasp of their functionality and usage within the Bitcoin network. Additionally, I'm interested in knowing if there are any security considerations or best practices to keep in mind when handling and sharing Bitcoin addresses.
