Communication then & now
Visual Communication
Visual communication as the name
suggests is communication through
visual aid & is described as the
conveyance of ideas & information in
forms that can be read or looked upon.
The smoke signal
   It is one of the oldest forms of long-distance
    communication. It is a form of visual
    communication used over long distance.
   In Ancient China, soldiers stationed along the Great
    Wall would alert each other of impending enemy attack
    by signalling from tower to tower.
   In this way, they were able to transmit a
    message as far away as 750 km(470 mi)
    in just a few hours.
Pigeon Post
   It is the use of homing pigeons to carry messages.
    Pigeons were effective as messengers due to their
    natural homing abilities.
   The pigeons were transported to a destination in cages,
    where they would be attached with messages, then
    naturally the pigeon would fly back to its home where
    the
    owner could read his mail.
   Pigeons have been used to great effect in
    military situations.
Mail
   Mail, or post, is a system for transporting letters & other
    tangible objects: written documents, typically enclosed in
    envelopes, & also small packages are delivered to
    destinations around the world.
   Anything sent through the postal system is
    called mail or post.
   A postal service can be private or public, though many
    governments place restrictions on private systems.
   Since the mid-19th century national postal systems have
    generally been established as government monopolies
    with a fee on the article prepaid.
Heliograph
   It is a wireless solar telegraph that signals by flashes
    of sunlight (generally using Morse code) reflected by
    a mirror. The flashes are produced by momentarily
    pivoting the mirror, or by interrupting the beam with a
    shutter.
   The heliograph was a simple but effective instrument for
    instantaneous optical communication over long
    distances during the late 19th & early 20th century.
Maritime flag
   It is a flag designated for use on ships, boats, & other
    watercraft.
   Naval flags are considered important at sea & the rules &
    regulations for the flying of flags are strictly enforced.
   The flag flown is related to the country of registration: so
    much so that the word "flag” is often used symbolically
    as a synonym for "country of registration".
Signal lamp
   It is a visual signalling device for optical communication
    (typically using Morse code).
   Modern signal lamps are a focused lamp which can
    produce a pulse of light. In large versions this pulse is
    achieved by opening & closing shutters mounted in front
    of the lamp.
Newspaper(Print Media)
   A newspaper is a
    scheduled publication containing news of current
    events, informative articles, diverse features,
    editorials, & advertising
   Johannes Gutenberg's work on the printing press
    began in approximately 1436.
   The invention of printing press led to an entire new
    era of mass communication. Newspapers,
    magazines, periodicals etc.
   This techinique of mass communication diversified
    with technology & is still the most used medium of
    mass communication.
   By 2007, there were 6,580 daily newspapers in the
Timeline Of Printing Press
Communication then & now
Oral Communication
Oral communication, while primarily
referring to spoken verbal communication,
can also employ visual aids & non-
verbal elements to support the conveyance
of meaning.
Oral communication includes speeches,
presentations, discussions, & aspects of
interpersonal communication.
Horn & Drums
   A horn is a tapered sound guide designed to provide
    an acoustic impedance match between a sound source
    & free air.
   This has the effect of maximizing the efficiency with
    which sound waves from the particular source are
    transferred to the air. Conversely, a horn can be used at
    the receiving end to optimize the transfer of sound from
    the air to a receiver.
Electrical telegraph
   It is a telegraph that uses electrical signals, usually
    conveyed via telecommunication lines or radio.
    The electromagnetic telegraph is a device for human-to-
    human transmission of coded text messages.
   It is the first form of electrical telecommunications.
   Later electrical telegraph networks permitted people &
    commerce to almost instantly transmit messages across
    both continents & oceans.
Telephone

    other.
   Developed in the mid-1870s by Alexander Graham Bell.
   The telephone has long been considered indispensable
    to businesses, households & is now one of the most
    common appliances in the developed world.
Photophone
   The photophone (also known as a radiophone) is
    a telecommunications device which allowed for
    the transmission of both articulated sounds & normal
    human conversations on a beam of light.
   The device was a precursor to fibre-optic
    communications that came into widespread use during
    the 1980s.
Radio
   Radio is the transmission of signals through free space
    by electromagnetic waves with frequencies significantly
    below visible light, in the radio frequency range, from
    about 3 kHz to 300 GHz. These waves are called radio
    waves.
   Electromagnetic radiation travels by means of oscillating
    electromagnetic fields that pass through the air &
    the vacuum of space.
Advanced Electrical
Signals
Television
   Television: (TV) is a telecommunication medium for
    transmitting & receiving moving images that can
    be monochrome (black-and-white) or coloured, with or
    without accompanying sound.
