Antonyms for "outputs" are "inputs" or "intakes." These terms refer to the flow of materials or information into a system, rather than out of it. Examples of inputs include raw materials, energy, or data that are used as the basis for producing something else. The concept of inputs is fundamental to various fields, such as biology, economics, and computer science. For instance, in biology, the inputs for the process of photosynthesis are water and carbon dioxide. In economics, inputs refer to the factors of production, such as labor, capital, and resources, that are combined to create goods and services. Similarly, in computer science, inputs represent the data that is processed or analyzed by a program.
