Document Summary

Chapter 4: the hardware layer (gates and circuits) Signals in a computer are considered to be within one range or the other. input signals and producing a single output signal. Any given electronic signal has a level of voltage. A voltage level in the range of 0 to 2 volts is considered low and is interpreted as a binary 0. A signal in the 2-5 volt range in considered high and is interpreted as a binary 1. A gate: a device that performs a basic operation on electrical signals, accepting one or more. Gates are combined into circuits to perform more complicated tasks. Circuit: a combination of interacting gates deigned to accomplish a specific logical function. In a circuit, the output value of one gate often serves as the input value for one or more other gates. The flow of electricity through a circuit is controlled by the designed logic of interacting gates.
