The defined term for a list of instructions that a microprocessor uses to manipulate data is a program. A program consists of a sequence of operations and commands that tell the microprocessor exactly what tasks to perform and in what order. This set of instructions can include various coding languages that the microprocessor interprets to execute functions such as calculations, data processing, and communication with other hardware.

To provide further context, other terms mentioned are often related to data manipulation but serve distinct purposes. A data stream refers to a continuous flow of data being transmitted, typically in real-time. An algorithm is a more general concept that outlines a step-by-step procedure for solving a problem, but it does not specify how to implement that procedure on a microprocessor. A protocol defines the rules and conventions for communication between devices, primarily focusing on data transfer rather than the direct manipulation of data by a microprocessor. Hence, the correct answer that aligns directly with a list of instructions for microprocessor operations is clearly the program.
