Pre-verbal communication is the first method that human babies use to express their emotions prior to speaking. These expressions start as involuntary and then become voluntary as the movements and effects of making them are learned.
Language it the vehicle which allows people to communicated their thoughts and ideas to other people and through print to save those ideas and not only share them with their contemporaries but to pass them down to the generations to come.
The development of the electric telegraph in the 1840s and the telephone in the late 1870s made rapid long-distance communications possible. Both media began in local areas and then rapidly spread to connect large parts of the Nation and the world.
Radio was the invention that allowed communications to become international and eventually connected the world. Starting out as point to point and later with the invention of the vacuum tube, became an international communication method.
In the 20th century the radio was invented and this allow an increased mobility for communications, such as ship to ship and police department broadcasts. When the vacuum tube was invented radio then became capable of international communications.
The development of electronic surveillance for legitimate purposes such as intelligence and law enforcement investigation, as well as for illegitimate purposes, spurred enactment of a number of laws intended to comprehensively address such activities. Congress enacted the first federal wiretap statute as a temporary measure to prevent disclosure of domestic telephone or telegraph communications during the First World War.
The first experimental communications satellite was launched in 1962. It was the first satellite to receive, amplify, and simultaneously re-transmit signals from earth. The development of satellite communications available not only to governments but also the commercial sector and individuals led to even greater volumes of communications worldwide.
The Internet is a globally distributed network comprising many voluntarily interconnected autonomous networks. It operates without a central governing body. However, to maintain interoperability, all technical and policy aspects of the underlying core infrastructure and the principal name spaces are administered by the Internet Corporation for Assigned Names and Numbers (ICANN), headquartered in Marina del Rey, California. ICANN is the authority that coordinates the assignment of unique identifiers for use on the Internet, including domain names, Internet Protocol (IP) addresses, application port numbers in the transport protocols, and many other parameters
