Is Tezos a Wallet?

Excuse me, I have a question that I've been puzzling over. Could you possibly clarify something for me? I've heard the term "Tezos" mentioned in the context of cryptocurrencies, and I'm a bit confused about its exact function. Could you tell me, is Tezos a wallet? Or is it something else entirely? I'm trying to understand the different components of the cryptocurrency ecosystem, and this is one piece of the puzzle that I'm still trying to fit into place. Your expertise in this area would be greatly appreciated. Thank you for your time and assistance.
