there are two computers communicating to each other by means of Parallel
port, that is data is transferred from one computer to other by the parallel
ports. the data line that joins the both computer is four bit, that is it can
transmit four bits at a time. And the communication protocol is
duplex(system composed of two connected parties or devices that can
communicate with one another in both directions). But in only one direction
at a time. And to each of the data line, LED is connected which glows when data bit one
or high ("1") is transmitted through the line. and it doesn't glow when data
bit is zero or low("0")when no data is transmitted through the computer, a test led is connected which glows showing NO COMMUNICATION. And turn off when communication starts
