COMMUNICATION AND ITS CHANGING TRENDS!
Cave
paintings:
The
oldest known symbols created for the purpose of communication were cave paintings, a form of rock art.
Most cave paintings date from 10,000 to 20,000 years ago. Most often, animals or hunting scenes were painted. Sometimes hands are
there too.
Pictogram:
A pictogram is a symbol representing
a concept, object, activity, place or event by illustration. Pictograms were used by various ancient cultures all over the world since around 9000 BC.
Pigeon
post:
Pigeon
post 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
their mail.
Telegraphs:
The first telegraphs came in the form of
optical telegraph, including the use of smoke signals, beacons, or reflected
light, which have existed since ancient times. The first successful semaphore
network was invented by Claude Chappe and operated in France from 1793 to 1846.
Electrical
telegraphs
The first suggestion for using electricity
as a means of communication appeared in the "Scots Magazine" in 1753.
Using one wire for each letter of the alphabet, a message could be transmitted
by connecting
the wire terminals in turn to an electrostatic machine, and observing the
deflection of pith balls at the
far end. Telegraphs employing electrostatic attraction were the basis of early
experiments in electrical
telegraphy in Europe but were abandoned as being impractical and were never
developed into a
useful communication system.
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.
Radio:
The radio has been the first device to
allow for mass communication. It has enabled information to be transferred far
and wide, not only nationally wide but internationally as well. The development
of the radio began in 1893 with Nikolai Tesla’s demonstration of wireless radio
communication in St. Louis, Missouri. The early uses of the radio were mainly
for maintaining contact between ships out a sea.
Telephone:
The earliest mechanical telephones were
based on sound transmission through pipes or other physical media. The
acoustic tin can telephone, or lover's phone,
has been known for centuries. It connects two diaphragms with a taut string or
wire, which transmits sound by mechanical vibrations from one to the other
along the wire. Early telephones were technically diverse. Some used a water
microphone, some had a metal diaphragm that induced
current in an electromagnet wound around a permanent magnet, and some
were dynamic.
Cordless phones:
In 1994, digital cordless phones in the 900 MHz frequency range
were introduced. Digital signals allowed the phones to be more secure and
decreased eavesdropping-it was relatively easy to eavesdrop on analog cordless
phone conversations.
Mobile phones:
The first handheld mobile phone was demonstrated by John F.
Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2
kilograms. In 1979, Nippon Telegraph and Telephone (NTT) launched the world's
first cellular network in Japan.
Smart phones:
Smartphones have
quickly gained popularity. Prior to the invention of smartphones, there were
several devices that were used including regular mobile phones, and PDA
devices. Eventually technology was combined and the concept of the smartphone
was born. The first concepts that eventually
led to the invention of the smartphone date back to the 1970s.
Internet:
The Internet debuted in 1969, known as the ARPANET and designed
mainly for the As the Internet gained popularity, communication changed
drastically.
Instead of using the telephone and incurring potentially high
long-distance charges, suddenly, it became possible to converse with people via
the Internet.
Email communication became available with the development of
Web-based services and Internet service providers. Instant messaging and
conversing in Internet forums also became prevalent military's use.
Social Networking:
The first social media site that everyone can agree actually was
social media was a website called Six Degrees. By the year 2000, around 100
million people had access to the internet, and it became quite common for
people to be engaged socially online. Although the younger generation of today
might not know about it, back in the early 2000’s the website My Space was the
popular place to set up a profile and make friends.
Facebook:
In 2004, Mark Zuckerberg launched what would soon become the
social media giant that would set the bar for all other social media services.
Facebook is the number one social media website today and it currently boasts
over a billion users.
You tube:
The domain name
"YouTube.com" was activated on February 14, 2005 with video upload
options being integrated on April 23, 2005. The first YouTube video, titled me
at the zoo, was uploaded on April 23, 2005, and shows co-founder Jawed Karim at
the San Diego Zoo.
Social media today
consists of thousands of social media platforms, all serving the same – but
slightly different purpose. Of course, some social media platforms are more
popular than others.
FUTURE OF COMMUNICATION:
Holographic Video
Calling
This is where holographic video call technology steps in and
with 4G and 5G technology on its way it could certainly be the next big thing
in future. if you will call someone, and they will appear in the room you’re
present.
Smart contact lenses
The tech is being developed as we speak. Scientists at the center
of microsystems technology at the University of Ghent have developed an LCD
display that can be embedded in a contact lens and, with the use of wireless
technology, show projected images. The contacts could be used for watching
movies, showing directions while driving or projecting text messages from a PC,
tablet or smartphone directly to the user’s eye.
Computer-screen glasses are already available from Google Glass
and thought to be only a few years from the mass market.
Eventually there would be no need to text or type anything
because a chip in the temples of the glasses would interface with brain waves
so the tiny micro-computer could know and transmit what a person is thinking,
but only if the person wants to have that information go out.
