    "Data communication is the process of using computing and communication technologies to transfer data from one place to another, or between participating parites. Data communication enables the movement of electronic or digital data between two or more network modes, regardless of geographical location, technological medium or data contents.";

    "In simplex mode, the commmunication is undirectional, as on a one way street. Only one of the two devices on a link can transmit, the other can only receive. Keyboard and traditional monitors are both examples of simplex. Keyboard can be only intorduce input, the monitor xan only accept the output. ";

    "In Half-Fuplex mode, each station can both transmit and receive is sending, the other can only receive, anmd vice versa. In this mode, the entire capacity of a channel is taken over by whichever of teo deveices is transmittnig at the time. Wakie-Talkie is the best example of half-duplex system.";

String point3Explanations =
    "In the Full-Duplex mode, both stations can transmit and receive simultaneously. This mde is like a two way traffic flowing in both directions at the same time. Here, signals going in either direction share the capacity of the link. Telephone network, online chatting are the example of full-duplex.";
