An Ethereum wallet is an application that allows you to manage your account, and ETH - the name of the cryptocurrency. Through your wallet, you can read your balance, send transactions, and connect to applications. Since your wallet is only a tool to manage and does not have custody of your funds, you can swap providers at any time.
These wallets are both physical hardware wallets that allow you to keep crypto offline, and digital wallets that are accessed through mobile applications and web browsers.
