A BCR (barcode reader) or scanner, also known as a POS (point of sale) scanner is a hardware input device capable of reading a barcode using a laser. It can also load the details of the product or log information about that product into a database. An example of a barcode reader is a supermarket barcode scanner that reads and logs the price of a product.

Like other input devices, a barcode reader is bringing in (inputting) information from the outside world into a computer or other electronic device. If the barcode reader also has a screen that displays (outputs) results or prints results, it would be considered an input/output device.

Barcode printers:

A barcode printer is a hardware device capable of printing adhesive barcodes that are attached to a product to identify it and help keep track of inventory.

Q7 Answer)

A bitmap is an array of bits that specifies the color of each pixel in a rectangular array of pixels. The number of bits devoted to an individual pixel determines the number of colors that can be assigned to that pixel. For example, if each pixel is represented by 4 bits, then a given pixel can be assigned one of 16 different colors (2^4 = 16). The following table shows a few examples of the number of colors that can be assigned to a pixel represented by a given number of bits.

So, 8 bit has 2^8 = 256 Number of colors that can be assigned to a pixel.
