Inputs refer to the resources or information that are put into a system to produce an output. In various contexts, such as computing or manufacturing, inputs can include data, materials, or energy. For example, in a computer program, user commands and data files serve as inputs that the program processes to generate results. In economics, inputs are the factors of production used to create goods and services. These can be categorized into three main types: land, labor, and capital. Each type of input plays a crucial role in the production process, influencing efficiency and overall output.
