Final answer:
The term 'manual input' represents the process of entering data into a system by hand, using devices like keyboards or touchscreens, and is essential for situations where automatic data entry is not feasible or when human judgment is necessary.
Step-by-step explanation:
The term 'manual input' refers to the process of entering data into a system by hand, as opposed to automatic data entry methods. This often involves a user typing data using a keyboard or entering it via a touchscreen. Manual input is an essential aspect of user interaction with computers and various software applications. It requires careful attention to detail to ensure that the data entered is accurate and free of errors.
Manual input methods are commonly used in situations where automatic data capture is impractical or when a human touch is necessary, such as entering unique or variable data that a computer cannot predict or when a level of human judgement is required.
