Question: Codes consisting of lines of varying widths or lengths that are computer-readable are known as-

Answer:

Codes consisting of lines of varying widths or lengths that are computer-readable are known as "barcodes." Barcodes are graphical representations of data that can be scanned and interpreted by barcode scanners or other devices equipped with barcode reading capabilities.

Barcodes are widely used in various industries for purposes such as product identification, inventory management, and tracking. They consist of a series of parallel lines or bars, with each bar representing a specific pattern of binary digits. The width or length of the bars and spaces between them encodes the information, which could be a product code, a serial number, or other relevant data.

When a barcode is scanned using a barcode reader or scanner, the device captures the pattern of the lines and converts it into a digital representation that can be processed by a computer system. This allows for quick and accurate data entry, eliminating the need for manual typing or data entry errors.

There are different types of barcode symbologies or formats, such as UPC (Universal Product Code), EAN (International Article Number), Code 39, QR Code, and many more. Each symbology has its own specifications and encoding rules, catering to specific use cases and requirements.

Overall, barcodes provide a convenient and efficient way to store and retrieve data in a computer-readable format, enabling automation, data capture, and streamlined operations in various industries.
