Question

question 7 (1 point) listen which of the following best describes optical scanning devices? 1) photoelectric devices that scan data 2) hand - held wands used to read data on merchandise tags 3) converts reflected light patterns into electronic impulses, which are accepted as input into the computer system 4) all of the choices are correct.

Explanation:

1. Option 1: Optical scanning devices are photoelectric as they use light - related principles to scan data.
2. Option 2: Hand - held wands (like barcode scanners, a type of optical scanning device) are used to read data on merchandise tags.
3. Option 3: The fundamental working principle of optical scanning devices is to convert reflected light patterns (e.g., from barcodes) into electronic impulses that can be input into a computer system.

Since all three options correctly describe aspects of optical scanning devices, option 4 is correct.

Answer:

1. All of the choices are correct.
