Final answer:
A keyboard is accessed through a character stream interface, which sends data one character at a time to the computer.
Step-by-step explanation:
A keyboard is an example of a device that is accessed through a character stream interface. When you type on a keyboard, each press of a key sends a character to the computer. Unlike block devices that send data in larger, fixed-size blocks, character devices send data one character at a time, making them more suitable for devices like keyboards where input is provided in a sequential manner.
