Which of the following is a device that uses a light source to read characters, marks, and codes and then converts them into digital data that a computer can process? A printer, such as that shown in the accompanying figure, creates images using a laser beam and powdered ink.

Which of the following is a device that uses a light source to read characters marks and codes?

optical character recognition devices
Abbreviated OCR, optical character recognition devices also use a light source to read special characters and convert them into electrical signals to be sent to the central processing unit.

Which of the following reads the magnetic stripe on back?

A magnetic stripe reader, also called a magstripe reader, is a hardware device that reads the information encoded in the magnetic stripe located on the back of a plastic badge.

What is the full from of OMR?

Optical mark recognition (also called optical mark reading and OMR) is the process of capturing human-marked data from document forms such as surveys and tests.

What is OMR and OCR?

The difference between OMR and OCR is that OMR is the abbreviation of optical mark recognition that is used to recognize the check and bubble marks on the paper; mostly exams and surveys, whereas OCR is optical character recognition that is used to recognize the characters from documents and collects and converts it …

What is input and output with examples?

An input is data that a computer receives. An output is data that a computer sends. Computers only work with digital information. Any input that a computer receives must be digitised. Often data has to be converted back to an analogue format when it’s output, for example the sound from a computer’s speakers.

How does a barcode and magnetic stripe protect the information?

Barcodes vs. Magnetic Encoding

1. Barcodes store information optically in parallel lines of different widths and spacing. The numbers.
2. Magnetic stripes are encoded with a unique serial number on a single stripe and are read by swiping them through a magnetic stripe card reader like the ones used to read credit cards.
