A barcode scanner is the device that captures barcodes on products. It uses a laser or camera to read the pattern of bars and spaces in a barcode, converting it into a digital signal that can be processed by a computer or point-of-sale system. Barcode scanners come in various forms, including handheld devices, fixed-mount scanners, and mobile scanning applications on smartphones.

What captures sound?
A microphone is a device that captures sound by converting acoustic energy into electrical signals. These signals can then be processed and recorded for playback or transmission.
A device which records what is spoken into it and then reproduces it?
The device you are referring to is called a voice recorder or a digital recorder. It captures audio input using a microphone and stores it digitally for playback at a later time. These devices are commonly used for taking notes, recording meetings or interviews, and for dictation purposes.
What is a recording device that measures the amount of air inhaled or exhaled?
A recording device that measures the amount of air inhaled or exhaled is called a spirometer. It is commonly used in medical settings to assess lung function and diagnose respiratory conditions. The device captures and records the volume of air during breathing cycles, providing important data for healthcare professionals.
What part of the plant captures sunlight the leaf root or stem?

What is is an electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve?
An electronic device that bypasses damaged portions of the ear and directly stimulates the auditory nerve is called a cochlear implant. This device consists of an external component that captures sound and converts it into digital signals, which are then transmitted to an internal component implanted in the cochlea. The internal device stimulates the auditory nerve, allowing the brain to perceive sound. Cochlear implants are typically used for individuals with severe to profound hearing loss who do not benefit from traditional hearing aids.
What is the purpose of a CCD scanner?

Why is barcode reader a direct input device?
A barcode reader is considered a direct input device because it captures data directly from a barcode and converts it into a digital format that can be processed by a computer or system. This process occurs in real-time, allowing for immediate data entry without the need for intermediary steps. By scanning barcodes, it eliminates manual data entry errors and enhances efficiency in tracking inventory or processing transactions.
What does a scanner do in ict?
In Information and Communication Technology (ICT), a scanner is a device that converts physical documents, images, or objects into digital format. It captures the content using sensors and translates it into a file that can be processed, stored, or shared on computers. Scanners are commonly used for digitizing paper documents, photos, and barcodes, facilitating easier access and management of information.
