Binary code is not a device. It is a numerical representation of data.
Binary code is not a device. It is a numerical representation of data.
A bar code printer or any kind of printer is an output device.
A bar code reader is an input Device. Although they sometimes output a visible light, the purpose is to gather data from a printed code and input that data into your system (computer, Point of Sale, etc.)
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.
Input because it is sending data to the computer.

To convert a decimal number to binary in Verilog, you can use the built-in reg or wire types to store the binary value. First, define a module and declare an input for the decimal number. You can then use an assignment statement to convert the decimal to binary by assigning the input directly to the output, as Verilog implicitly handles the conversion. For example: module decimal_to_binary(input [7:0] decimal, output reg [7:0] binary); always @(*) begin binary = decimal; // Implicit conversion from decimal to binary end endmodule This code will take an 8-bit decimal input and output its binary representation.
Red: Input ( + ) Black: Input ( - ) Green: Output ( + ) White: Output ( - )
Input - the reader is reading the bar code and putting the information into the computer
These are all example's of Data Input device's - as opposed to Data Output Device's like Monitor's, Projector's, Printer's etc.
