In the history of the humanity, the man has used different forms of communication like the communication with signs, up to the communication distantly by meansof technological advanced devices. The communication by cell phone is one of the most important inventions in the history. It is very important all over of the world.Many people cannot live without a cell phone.
The telephone was invented by Alexander Graham Bell in 1876, and the wireless communication has his roots in the invention ofthe radius as Nikolai Tesla in the decade of 1880. It was only natural that these two great technologies would eventually be combined. The first cell phone of the history isMotorola DynaTAC 8000X that appeared for the first time in the year of 1983.
New technology grows everyday and the cell phone is one these. Its function is very importantin the days. Some examples are: people can talk to anyone on the planet from just about anywhere and report to another person that is far. They can even use the built-incalculator for simple math, send or receive e-mail, get information (news, entertainment, stock quotes) from the Internet, play games, watch TV, send text message, mp3,between others.
Before the invention of a cell phone the life of people was more complicated because the distance was terrible for communication. Now it is very important.One clear example is when anyone person crashes theirs car, they can immediately call the police. It is so easy to use it.
I think that we can give thanks to the cellphone because we have done more advanced in the trade, in technology and in communication. Also I believe that is very necessary for the human development for the century.
