Answer Details
The rectangular image that consists of black lines and white spaces representing data that can be optically read is called a barcode. Barcodes are widely used in various industries and businesses to automate the process of identifying and tracking products, inventory, and other data. The black lines and white spaces in a barcode represent a specific code or information that can be read by a barcode scanner or reader. When the scanner reads the barcode, it translates the code into a digital signal that can be processed by a computer or other devices. This makes barcodes a simple and efficient way to store and retrieve information.
