A device that selects one of several inputs to be placed on the output is a multiplexer.

• A VARIABLE can be thought of as a piece of scrap paper used to write down some numbers that can be used later.
• A circuit that converts some binary code into a singular active output representing its numerical value is a comparator.
• A logic circuit that determines if one input is equal to another is called a comparator.
• The select inputs to a multiplexer may also be called address lines.
• It is normal for more than one decoder output to be active at the same time.
• In HDL, a process is usually thought of as a wire connecting two points in a circuit.
• When data input I1 of a 74148 octal-to-binary encoder is active, the data output is: A0 = 0 A1 = 0 A2 = 1
• Basically, a multiplexer changes parallel data inputs to a serial output.
• The outputs of a 7485 four-bit magnitude comparator when the inputs are A = 0110 and B = 1010 are: A < B is 1 A = B is 0 A > B is 1
• Modern computers transfer data between different devices over a common set of connecting lines called a data bus.
