Banking is the business of securing the funds of others. Banks lend this money, earning interest and profit for themselves and their customers. In simple words, a bank is a type of financial institution that is authorised to take deposits and provide loans. They may, however, provide additional financial services. The term "bank" can apply to a variety of financial institutions, such as trust companies, savings and loan associations, credit unions, and any other sort of deposit-taking institution. You can enhance your skills or be a part of the banking sector by doing a diploma in banking and finance.
