The automated input technique that eliminates the need for manual keying of input data is known as Optical Character Recognition (OCR). OCR technology scans and converts different types of documents, such as printed or handwritten text, into machine-readable data. This process enables automatic data entry, significantly improving efficiency and reducing human error in data processing. Other similar techniques include barcode scanning and RFID technology, which also automate data capture without manual input.
Ya its manual input device
A webcam is not typically classified as an automated input device; rather, it is a type of input device that captures video and images when activated by the user or a software application. While it can operate automatically in certain contexts (like video conferencing software), it requires user input or action to function. Therefore, it primarily serves as a manual input device rather than an automated one.
Manual keying offers several advantages, including enhanced accuracy in data entry, as individuals can carefully review and correct information as they input it. It allows for greater flexibility in handling complex or unique data that automated systems might struggle with. Additionally, manual keying can be more cost-effective for small-scale operations or one-time tasks, eliminating the need for expensive software or technology investments. Lastly, it can provide a personal touch in customer service or data handling scenarios where human interaction is valued.
The difference is that an Non-Automated Input Device is used when the user is the source of input (e.g the data will be typed in or draw by the user), while Automated Input Devices are use in situations where the data is already prepare in a form which the input device can pick up and transmit directly into the computer.

It is an device that does not need a human to interact with to work correctly
The two primary ways of entering data are manual input and automated input. Manual input involves users directly typing or selecting data through interfaces like forms or spreadsheets. Automated input utilizes technology such as sensors, scanners, or software integrations to collect and enter data without human intervention, enhancing efficiency and accuracy.
A manual system analysis require individuals to supply input directly into a system designed to simulate real life events. An automated system is controlled by technology to automatically supply input.
Its fairly self explanatory, put the input IN then check the output at the OUTPUT.
Boundary Value Analysis
In FSK the output frequency is dependent on the input bit stream. Here 2 (for Binary FSK) different carrier frequencies are used and they are switched according to input bit stream. When input is at logic1 output is freq. f1 and when input at logic0 output is freq. f2, where f1 and f2 are different.
Automated input devices are more accurate because there is a decreased chance of human error due to the following factors; computers never get tired, they are not biased in any way and more accurate calculations can take place quickly and repetively. The same task can be performed with 100% efficiency.
