This is a 22 slide, highly animated, power point presentations on Inventions - The Telephone. Each of the presentation slides are editable so you can change it to fit your individual needs.
One of the most important and revolutionary inventions which has impacted modern day communication is the invention of the telephone. The idea behind the telephone is simple: a system which converts sound into a series of electrical impulses of differing frequencies, and then reverses this procedure to re-create the sound, typically a human voice.
Sounds simple enough, but it took many years and an array of different inventors to finally succeed with the technology. Today the telephone is an all purpose tool. It is used in the home, business and in education. It is a source of entertainment and a vital resource to the illiterate as well as the literate.
The telephone has become an integral part of our lives since it was invented.
