Basic Elements of Communications System

The following five basic elements are required for any communication System.
1.   Massage:  Massage is the information that is communicated over the communication system.  It            includes text, audio, video and images.
2.  Sender:      The node that is used for transferring data is called transmitter, source or sender.  In
     recent digital communication system, the source is mostly a computer or a mobile device.
3.  Medium.    Medium is the pathway through  which data is sent from one point to another.  If the
     receive and transmitter are within a building, a wire can connect them.  If they are located at different
    locations, they may be connected through telephone line, fiber optics or microwaves.
4.  Receiver:  The node that receives the data is called receiver.  The receiver can be a computer, mobile
    device or a printer.
5.  Protocols:  A protocol is set of  rules which govern the data transmission between sender and receiver.
    Without protocol the information is useless for the receiver as a person understanding only Urdu cannot
    understand English messages.  Therefore messages sent over through communication protocols can only
   be understood by the receiver.

Poem

Not gold, but only men can make
A people great and strong;
Men who for truth and honour's sake
Stand fast and suffer long.
Brave men who work while others sleep,
Who dare while other fly....
They build a nation's pillars deep
And left them to the sky.
