I have experienced people always mixed up with bitcoin wallet, address and clients. So I research a bit more to write clear.
What is address? I don't like to write my own word. I picked best quote for that.
Sources:- Bitcoin address.A Bitcoin address, or simply address, is an identifier of 26-35 alphanumeric characters, beginning with the number 1, 3 or bc1 that represents a possible destination for a bitcoin payment. Addresses can be generated at no cost by any user of Bitcoin. For example, using Bitcoin Core, one can click "New Address" and be assigned an address. It is also possible to get a Bitcoin address using an account at an exchange or online wallet service.

What is wallet?Sources:- Bitcoin wallet.A Bitcoin wallet is a collection of private keys but may also refer to client software used to manage those keys and to make transactions on the Bitcoin network.

Useful information about the state of the network and transactions.
