The Internet can be used in in different ways: for distributing and retrieving information, for one-to-one, one-to-many and many-to-many communication, and for the access services. Accordingly, there are different services on offer. The most important of these are listed below.

Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology to process statistical data collected during the US census in 1890, thus speeding up US census data analysis from eight to three years. Hollerith's application of Jacquard's invention was used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with
Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone used them for the preparation, storage, and transmission of data for the first time. Through paper tapes telegraph messages could be stored, prepared off-line and sent ten times quicker (up to 400 words per minute). Later similar paper tapes were used for programming computers.
1809
With Samuel Thomas Soemmering's invention of the electrical telegraph the telegraphic transmission of messages was no longer tied to visibility, as it was the case with smoke and light signals networks. Economical and reliable, the electric telegraph became the state-of-the-art communication system for fast data transmissions, even over long distances.

1861
The telephone was not invented by Alexander Graham Bell, as is widely held, but by Philipp Reiss, a German teacher. When he demonstrated his invention to important German professors in 1861, it was not enthusiastically greeted. Because of this dismissal, he was not given any financial support for further development.
And here Bell comes in: In 1876 he successfully filed a patent for the telephone. Soon afterwards he established the first telephone company.

The advertising industry has always relied on media to transport their messages and disseminate them to the public. Depending on the product or service advertised and the audience targeted different media are used. Besides cinema and outdoor advertising (posters etc.) the huge majority of ads is placed within the classical media landscape, which includes TV, newspapers, magazines and radio.
Whereas in most cases only a relatively small fraction of advertising budgets is spent on cinema, outdoor and radio advertising, newspapers, magazines and TV account for more than two thirds of the money spent on ads. Still with the growing popularity of new media advertisers and marketers have recently also discovered digital networks and especially the Internet for their purposes.

With the rapid growth of the Internet and its audience advertisers now have a new medium at their disposal. The placement of the first banner ads in 1994 marks the birth of Internet advertising. Although the advertising industry at first hesitated to adopt the new medium, two facts brushed away their doubts:
Migrating Television Audiences: The increased use of the Internet led people to redistribute their time budget. Whereas some cut down on eating and sleeping, more than a third reduced watching television and instead uses the WWW.
Interesting Internet Demographics: While methodologies and approaches of research organizations studying the demographic composition of the Internet vary, the findings are relatively consistent: Internet users are young, well educated and earn high incomes.
Considering those findings, the Internet in the first place seems to become inevitable to be included in media planning, as part of the audience shifts from TV to the WWW, and secondly, because demographics of the Internet user population are irresistible for marketers.

While the digital divide might bring up the idea that enterprises will be able to sell more and more computers during the next years another truth looks as if there was no hope for a certain percentage of the population to get out of their marginalization, their position of being "have nots".
Studies show that the issue of different colors of skin play a role in this, but more than "racial" issues it is income, age and education that decides about the have and have nots.
There exist ~ 103 million households in the USA.
~6 million do not even have telephone access. Why should they care about computers?
The digital divide cuts the world into centers and peripheries, not into nations, as it runs through the boarder between the North and the South as well as through nations.

"Globalization is to no small extent based upon the rise of rapid global communication networks. Some even go so far as to argue that "information has replaced manufacturing as the foundation of the economy". Indeed, global media and communication are in some respects the advancing armies of global capitalism."
(Robert McChesney, author of "Rich Media, Poor Democracy")
"Information flow is your lifeblood."
(Bill Gates, founder of Microsoft)
The usefulness of information and communication technologies increases with the number of people who use them. The more people form part of communication networks, the greater the amount of information that is produced. Microsoft founder Bill Gates dreams of "friction free capitalism", a new stage of capitalism in which perfect information becomes the basis for the perfection of the markets.
But exploitative practices have not disappeared. Instead, they have colonised the digital arena where effective protective regulation is still largely absent.

Satellite communication
Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks.

When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers.
As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost.
Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

Seagram is the largest producer and marketer of distilled spirits in the world. It is headquartered in Montreal, Que. The company began when Distillers Corp., Ltd., a Montreal distillery owned by Samuel Bronfman, acquired Joseph E. Seagram & Sons in 1928. Under the leadership of the founder's son, Edgar M. Bronfman, who became head of the company in 1971, the firm diversified during the 1950s and '60s from its original base of blended whiskies into the production and marketing of scotch, bourbon, rum, vodka, gin, and many different wines. It also expanded into the European, Latin American, East Asian, and African markets with its products. The company adopted its present name in 1975. It produces more than 400 different brands of distilled spirits and wines. Edgar M. Bronfman, Jr., took over as head of the company in 1989. Seagram in 1995 purchased MCA Inc., a media and entertainment firm, from the Matsushita Electric Industrial Company.

Robot relates to any automatically operated machine that replaces human effort, though it may not resemble human beings in appearance or perform functions in a humanlike manner. The term is derived from the Czech word robota, meaning "forced labor." Modern use of the term stems from the play R.U.R., written in 1920 by the Czech author Karel Capek, which depicts society as having become dependent on mechanical workers called robots that are capable of doing any kind of mental or physical work. Modern robot devices descend through two distinct lines of development--the early

The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems.
Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all.
In digital systems, bandwidth is data speed in bits per second (bps).

DARPA (Defense Advanced Research Projects Agency) is the independent research branch of the U.S. Department of Defense that, among its other accomplishments, funded a project that in time was to lead to the creation of the Internet. Originally called ARPA (the "D" was added to its name later), DARPA came into being in 1958 as a reaction to the success of Sputnik, Russia's first manned satellite. DARPA's explicit mission was (and still is) to think independently of the rest of the military and to respond quickly and innovatively to national defense challenges.
In the late 1960s, DARPA provided funds and oversight for a project aimed at interconnecting computers at four university research sites. By 1972, this initial network, now called the
