1700 - 1800 A.D.

1713
First typewriter patent filed

In 1714 Henry Mill got granted a patent for his idea of an "artificial machine or method" for forgery-proof writing. Still it was not before 1808 that the first typewriter proven to have worked was built by Pellegrino Turri for his visually impaired friend, the Countess Carolina Fantoni da Fivizzono. The commercial production of typewriters began in 1873.

For a brief history of typewriters see Richard Polt, The Classic Typewriter Page, http://xavier.xu.edu/~polt/typewriters.html

1727
First photocopies

Searching for the Balduinist fluorescenting phosphor (Balduinischer Leuchtphosphor), an artificial fluorescent, Johann Heinrich Schulze realized the first photocopies, but did not put them into practical use.

The first optical photocopier was not patented before 1843, when William Henry Fox Talbot got granted a patent for his magnifying apparatus.

In 1847 Frederick Collier Bakewell developed a procedure for telecopying, a forerunner of the fax machine. Yet it was not before 1902 that images could be transmitted. Almost 200 years after Schulze's discovery, for the first time photo telegraphy was offered as a telecommunication service in Germany in 1922.

1794
Fixed optical network between Paris and Lille

Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.
Because the communication system was designed for practical military use, the transmitted messages were encoded. The messages were kept such a secret that even those who transmit them from tower to tower did not capture their meaning; they transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.

Forerunners of Chappe's optical network are the Roman smoke signals network and Aeneas Tacitus' optical communication system.

For more information on early communication networks see Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks.

Governmental Influence

Agencies like the NSA are currently able to eavesdrop on anyone with few restrictions only - though other messages are spread by the NSA.
Theoretically cryptography can make that difficult. Hence those agencies speak up for actions like introducing trapdoors to make it possible to get access to everybody's data.

See the U.S. discussion about the Clipper Chip some years ago:
http://www.epic.org/crypto/clipper/
http://www.cdt.org/crypto/admin/041693whpress.txt

While encryption offers us privacy for the transmission of data, we do not only wish to have it but also need it if we want to transport data which shall not be seen by anyone else but the recipient of our message. Given this, the governments and governmental institutions/organizations fear to lose control. Strict laws are the consequence. The often repeated rumor that the Internet was a sphere of illegality has been proven wrong. Some parts are controlled by law very clearly. One of them is cryptography. Prohibition of cryptography or at least its restriction are considered an appropriate tool against criminality. Or one should say: had been considered that. In the meantime also governmental institutions have to admit that those restrictions most of all work against the population instead against illegal actors. Therefore laws have been changed in many states during the last five years. Even the USA, the Master of cryptography-restriction, liberated its laws in December 1999 to be more open-minded now.

Server

A server is program, not a computer, as it sometimes said, dedicated to store files, manage printers and network traffic, or process database queries.

Web sites, the nodes of the World Wide Web (WWW), e.g., are stored on servers.

Economic rights

The economic rights (besides moral rights and in some cases also neighboring rights) granted to the owners of copyright usually include 1) copying or reproducing a work, 2) performing a work in public, 3) making a sound recording of a work, 4) making a motion picture of a work, 5) broadcasting a work, 6) translating a work and 7) adapting a work. Under certain national laws some of these rights are not exclusive rights of authorization but in specific cases, merely rights to remuneration.

Artificial Intelligence

Artificial Intelligence is concerned with the simulation of human thinking and emotions in information technology. AI develops "intelligent systems" capable, for example, of learning and logical deduction. AI systems are used for creatively handling large amounts of data (as in data mining), as well as in natural speech processing and image recognition. AI is also used as to support decision taking in highly complex environments.

Fiber-optic cable networks

Fiber-optic cable networks may become the dominant method for high-speed Internet connections. Since the first fiber-optic cable was laid across the Atlantic in 1988, the demand for faster Internet connections is growing, fuelled by the growing network traffic, partly due to increasing implementation of corporate networks spanning the globe and to the use of graphics-heavy contents on the World Wide Web.

Fiber-optic cables have not much more in common with copper wires than the capacity to transmit information. As copper wires, they can be terrestrial and submarine connections, but they allow much higher transmission rates. Copper wires allow 32 telephone calls at the same time, but fiber-optic cable can carry 40,000 calls at the same time. A capacity, Alexander Graham Bell might have not envisioned when he transmitted the first words - "Mr. Watson, come here. I want you" - over a copper wire.

Copper wires will not come out of use in the foreseeable future because of technologies as DSL that speed up access drastically. But with the technology to transmit signals at more than one wavelength on fiber-optic cables, there bandwidth is increasing, too.

An entertaining report of the laying of the FLAG submarine cable, up to now the longest fiber-optic cable on earth, including detailed background information on the cable industry and its history, Neal Stephenson has written for Wired: Mother Earth Mother Board. Click here for reading.

Susan Dumett has written a short history of undersea cables for Pretext magazine, Evolution of a Wired World. Click here for reading.

A timeline history of submarine cables and a detailed list of seemingly all submarine cables of the world, operational, planned and out of service, can be found on the Web site of the International Cable Protection Committee.

Internet Software Consortium

The Internet Software Consortium (ISC) is a nonprofit corporation dedicated to the production of high-quality reference implementations of Internet standards that meet production standards. Its goal is to ensure that those reference implementations are properly supported and made freely available to the Internet community.
