Final answer:
Rendering other services by commercial banks includes various supervisory and functional support activities such as account maintenance, loan processing through the discount window, and check processing, all performed to facilitate banking operations for other institutions and for government transactions.
Step-by-step explanation:
Rendering other services by a commercial bank refers to various non-traditional banking activities that support the day-to-day operations of both other financial institutions and the government. An example of this is the services provided by the Federal Reserve to commercial banks and other depository institutions. These services include maintaining accounts for commercial banks, processing loan requests through the discount window facility, and handling check processing. For instance, when a person writes a check to a grocery store, the store deposits the check and then the store's bank works with the customer's bank to complete the transaction, with the Fed often facilitating the transfer of funds.
