When people talk about banks, they usually mean retail banks, also known as high street banks or commercial banks. The other main form of banking is investment banking (or merchant banking). In practice, many banks have both retail and investment wings and are thus “universal banks”.
Retail banks engage in all sorts of activities, most of which are variations on managing accounts or lending out money.
