What is the main difference between a barcode scanner and optical character recognition?

Answer and explanation

Correct answer: A barcode scanner reads fixed line patterns while optical character recognition identifies characters

The governing concept is the difference between machine-readable codes and printed language. A barcode scanner detects the widths and spaces of a coded pattern, whereas optical character recognition, or OCR, analyses the shapes of printed letters and converts them into editable digital text. Therefore, option A is correct. Options B and C are too narrow or false, and a barcode scanner is an input device, not an output device, so D is incorrect.
