Is an Optical Character Recognition (OCR) device classified as an input or output device?

An Optical Character Recognition (OCR) device is classified as an input device because its primary function is to convert different types of documents, such as scanned paper documents or PDFs, into editable and searchable data. This process involves capturing images of text and then using software algorithms to identify and translate the shapes of characters into machine-encoded text. As a result, OCR devices are utilized to input data into computer systems for processing, editing, or storing in a database.

While some devices may have dual functions or might be part of a system that includes output functionalities, the core operation of OCR specifically pertains to the input of data, confirming its classification as an input device.
