Input (Data) refers to the information that is fed into a system for processing. This can include numbers, text, images, or any other type of information that can be analyzed or manipulated. In computing, input data is essential for tasks such as calculations, data analysis, and decision-making. Input data can come from various sources, including user entries, sensors, or external databases. For example, when you enter your name and age into a form, that information becomes input data for the system. Properly managing and organizing input data is crucial for achieving accurate results in applications like machine learning and data analysis.
