Is an optical reader that uses laser beams to read bar codes?
Yes, an optical reader that uses laser beams to read bar codes is commonly known as a laser barcode scanner. These devices emit laser light to scan and capture the information encoded in bar codes, which is then processed and converted into readable data. Laser scanners are widely used in retail, logistics, and inventory management due to their speed and accuracy. They can read bar codes from a distance and are often preferred for their efficiency in high-volume scanning environments.

Which storage device uses laser beams to read and write?
Laser beams are used to read and write data on CDs and DVDs. Apart from writing on these disks, the laser beam can also be used to erase the data stored or even overwrite the data stored with fresh data depending on the type of disk used.
How are bar codes read?
Bar codes are read by a bar code reader. A low-powered laser in a bar code scanner emits a beam that crosses the bar code, generating a series of light and dark reflected flashes. These are read by the sensitive laser detector in the scanner and decoded to produce the numerical values shown on the label. These are compared to the codes in the store's computer to identify the item, look up the price, and add it to the register bill. Modern self-service check-outs have lasers that scan in two perpendicular directions, to read barcodes in any position relative to the scanner.
Is a barcode scanner a input or output?
A bar code scanner is an input device. While it does contain a laser, the laser is used to read the data, not to communicate anything to the user. The bar code scanner reads the UPC codes into the cash register or point of sale system.
How do CD-ROMs read information?
Compact Disc-Read Only Memory (CD-ROM) drives use laser beams to read information on a rotating synthetic disk.
Is a barcode scanner an input or output device?
A bar code scanner is an input device. While it does contain a laser, the laser is used to read the data, not to communicate anything to the user. The bar code scanner reads the UPC codes into the cash register or point of sale system.
