A wallet is a place to hold tokens, it might be online at an exchange, at your browser like metamask or a piece of software running on your computer or mobile phone.
A wallet has an address and it’s protected by a seed phrase that is used to restore it on another device and usually by other methods like pin or passwords to protect it from misuse.
Each wallet is used on a network and others, allow several networks, providing different addresses on each one to receive the funds or cryptocurrencies.
