messages. The growth and development of science and technology have
developed various means of communication such as telephone, radio, TV,
newspaper, teleprinter, fax machine, e-mail, etc. Now communication
has become easier.
Post Office
Letters, money orders and parcels can be sent to different
places through the post office. The cost of sending
them can be paid through stamps, which we can buy
from the post office. The hobby of collecting stamps
is called philately.
The telegraphic method was invented and developed by
Samuel Morse. This method of sending messages used
telegraph wires and cables. It used a coded language of
dots and dashes. The instrument is called Morse Key.

Teleprinter
The invention of the teleprinter was very useful in sending telegrams
at a very fast rate. It could send messages more efficiently than the
telegraphic machine. It was an automatic system in which the teleprinter
could print the letters as the messages were sent from one end to another.
The telegram service was officially stopped in India on 14 July 2013.
Telephone
The telephone further improved the system of
communication from one person to another. It helped
us talk directly with other persons. The telephone was
invented in 1876 by Alexander Graham Bell in the USA.
Many new changes have been introduced in telephonic
communication. Today, we have the STD (Subscriber’s
Trunk Dialling) facility and mobile phones. Today, the
telephone is the most popular means of communication.
