Hieroglyphic Language


Hieroglyphics is the oldest language in the world. It was used in 3500 BC by Egyptians. The dates of invention varies by research. This language has been used from early to end of the Egyptian empire. Hieroglyphics is very hard to learn. It has different types of pictures instead of letters. This language was found on limestone. This was one of the first discoveries in communication. This was a new way of communication. They used to carve messages on the wall, limestones and wood. This was a new way to convey the messages to eachother.

FAX machine


The FAX was originally invented in 1843 by Alexander Bain. The fax is a method of encoding data, transmitting it over a telephone line and receiving a hard copy of the text, line drawings, or photographs at a remote location. The fax needs is consists of image scanner, a modem and a printer. Fax was a revolutionary invention for communication because it was a fast way to transmit information. in 1840's other way to transmit information was mail which would take couple of days to deliever. Fax would take couple of minutes to transmit the information. Invention of fax was a major discovery at that time.

Telegraph to telephone



In 1870's Alexander Graham Bell and Elisha Gray both independently invented a device that could transmit speech electrically. Thier designs were similar. Both rushed thier designs to the patent office. Alexander Graham Bell patent his telephone first. Both inventors had a huge legal battle over invention of telephone, which Bell won. So Alexander Graham Bell is considered the inventor of the phone. Before the invention of the telephone, telegraph was a major medium of communication. The Telegraph was establushed mean of communication for past 30 years. It was a revolutionary invention. It took communication to a whole new level. It opened up a new window for communication and technology. The telegraph and telephone are both wire-based electrical communication system and Bell invented telephone in attempts to improve telegraph. The telephone was better than telegraph mainly because voice transfer with electricity. The telephone was a revolutionary invention in communication technology.

Typewriter


As we all know what this is, this is a picture of a typewriter. Before the computers and cell phones, this machine was used for a long time. Although some people might say that y do we need a typewriter? But typewriter is still being used in some small countries. And type writer is inexpensive and easy to use. Typewriters were the first writing tool after the ink pen and a tree leaf. In today’s world people just go online and send an email and communicate via computer. But, back then they had to type a paper in this equipment. Although it took so much time and energy, it was reliable. Nowadays, if we don’t have electricity we can’t use most of the communication devices. But this typewriter does not need any electricity or any type of natural resource to run it. All it needs is an Ink, and it is ready to use.
Here is the wikipedia web site where it shows most the typewriters from the past to present.

CB Radio

We often think, what if all the satellites and communication towers shuts down? There are few ways to still communicate and find out what’s going on around nearby area. Some of you might know what CB radio is, but those of you who don’t know what it is may question. How does it work? And don’t we need satellites or towers to communicate? The answer is no, we do not need satellites or towers. This old technology only uses an antenna which gets the signal out and the other is a receiver, which scrambles a signal from the antenna. People in today’s society still use this technology, people who travels a lot outside of a network area. So, this technology is also effective even though some people might have never used it.

Here is a link of a short video, that shows how CB radio works.

Use Of A Telegraph

This is one of the eqipments that was used in early 1900s. I think this is one of the best ways of a communication because it is easy to use and more reliable than anything that we use in todays latest technologies. This telegraph was also showed in a movie called "transformers", where they had problems communicating with other people at the near death situation. So, it shows that even though we have a good technology existing today, there is still some hope for telegraph to be used in a near future.

Beginning of Communication


Pigeons were used as convey massages in early days. They were called pigeon messengers. Pigeons were trained to deliver the parcel or note to particular places.
These pigeons are specially breded. They have trained to learn their way home over a long distance. Notes or parcel were tied to pigeon's legs or sometimes put in their mouths. First time this pigeon messengers were used in 776 BC. This technique was excessively used in World War I.

Here is a video that shows use of pigeon messengers in World War I.
