The 17th Century: The Invention of the First "Computers"

The devices often considered the first "computers" in our understanding were rather calculators than the sophisticated combination of hard- and software we call computers today.

In 1642 Blaise Pascal, the son of a French tax collector, developed a device to perform additions. His numerical wheel calculator was a brass rectangular box and used eight movable dials to add sums up to eight figures long. Designed to help his father with his duties, the big disadvantage of the Pascaline was its limitation to addition.

Gottfried Wilhelm von Leibniz, a German mathematician and philosopher, in 1694 improved the Pascaline by creating a machine that could also multiply. As its predecessor Leibniz's mechanical multiplier likewise worked by a system of gears and dials. Leibniz also formulated a model that may be considered the theoretical ancestor of some modern computers. In De Arte Combinatoria (1666) Leibniz argued that all reasoning, all discover, verbal or not, is reducible to an ordered combination of elements, such as numbers, words, colors, or sounds.

Further improvements in the field of early computing devices were made by Charles Xavier Thomas de Colmar, a Frenchmen. His arithometer could not only add and multiply, but perform the four basic arithmetic functions and was widely used up until the First World War.

Beautiful bodies

However, artificial beings need not be invisible or look like Arnold Schwarzenegger in "Terminator". "My dream would be to create an artificial man that does not look like a robot but like a beautiful, graceful human being. The artificial man should be beautiful". Nadia Thalman's hopes for beautiful robots may become reality in the work of MIRALab, a research laboratory attached to the University of Geneva dedicated to realistic modelling of human functionalities. The laboratory has produced an artificial Marylyn Monroe showing just how beautiful artificial creatures can be, and there is a biography featuring details of her career and her - however virtual - love life. Yet beautiful creatures have been made before, at leas on the movie screen. Frank-N-furter, the protagonist of the Rocky Horror picture show ("I've been making a man / with blond hair and a tan / and he is good for relieving my /tension) did set remakrable esthetic standards.

While in Hindu mythology, avatars are bodies chosen by gods for their representation on earth, often animals such as swans or horses, the avatars populating cyberspace have a different function. The cyber bodies of real people, often 3 dimensional images of creatures whose aesthetics reflects both the tastes prevalent in the entertainment and advertising industries as the state of art in visual representation.

Agostino Ramelli's reading wheel

Agostino Ramelli designed a "reading wheel", which allowed browsing through a large number of documents without moving from one spot to another.

The device presented a large number of books - a small library - laid open on lecterns on a kind of ferry-wheel. It allowed skipping chapters and browsing through pages by turning the wheel to bring lectern after lectern before the eyes. Ramelli's reading wheel thus linked ideas and texts and reminds of today's browsing software used to navigate the World Wide Web.

Bandwidth

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).

Proxy Servers

A proxy server is a server that acts as an intermediary between a workstation user and the Internet so that security, administrative control, and caching service can be ensured.

A proxy server receives a request for an Internet service (such as a Web page request) from a user. If it passes filtering requirements, the proxy server, assuming it is also a cache server, looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.
