Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early
Therefore
After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer.
The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed.
Of extraordinary importance for the evolution of digital computers and

Adbusters, well known as fighters against corporate disinformation, injustices in the global economy and "physical and mental pollution", timely for the WTO Conference purchased three billboards in downtown Seattle. Featuring an image with the text "System Error - Type 2000 (progress)", the billboards were meant to challenge "... the WTO's agenda of global corporate growth and expose what isn't reflected in the United State's GNP - human and environmental capital."
At the same time RTMark went on-line with its spoof WTO website http://gatt.org. Shortly after its release WTO Director-General Mike Moore accused RTMark of attempting to "undermine WTO transparency" by copying the WTO website's design and using "domain names such as `www.gatt.org` and page titles such as 'World Trade Organization / GATT Home Page' which make it difficult for visitors to realize that these are fake pages." http://gatt.org is not the first time that RTMark has used website imitation aiming at rendering an entity more transparent. RTMark has performed the same "service" for

Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and
Especially on the World Wide Web, documents are often retrieved by entering keywords into so-called search engines, sets of programs that fetch documents from as many
Among other things that is the reason why the World Wide Web is not simply a very huge database, as is sometimes said, because it lacks consistency. There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes
According to the Internet domain survey of the
Backbone networks are central networks usually of very high bandwidth, that is, of very high transmitting capacity, connecting regional networks. The first backbone network was the
