What is defined as 'input' in computer processing?

Input in computer processing refers specifically to the data supplied to the computer for analysis and operation. This information is essential as it forms the foundation upon which the computer performs tasks, makes decisions, and generates outputs. Input can come in various forms including keyboard entries, mouse clicks, sensor readings, and data from external files or databases.

Understanding input is crucial for grasping how computers operate because the efficiency and correctness of processing largely depend on the quality and nature of this input data. Without properly defined input, the computer may not execute tasks correctly or may produce unexpected results.
