Epilogue As scientists are working hard on a quantum computer and also on quantum cryptography one can imagine that another revolution in the study of encryption has to be expected within the next years. By then today's hardware and software tools will look extraordinary dull. At the moment it is impossible to foresee the effects on cryptography and democratic developments by those means; the best and the worst can be expected at the same time. A certain ration of pessimism and prosecution mania are probably the right mixture of emotions about those tendencies, as the idea of big brother has come into existence long ago. At the same time it will - in part - be a decision of the people to let science work against them or not. Acceleration of data-transmission calls for an acceleration of encryption-methods. And this again falls back on us, on an acceleration of daily life, blurring the private and the public for another time. We live in an intersection, job and private life growing together. Cryptography cannot help us in that case. The privacy in our mind, the virtuality of all private and public lies in the field of democracy, or at least what is - by connection to the Human Rights - regarded as democracy. |

The 17th Century: The Invention of the First "Computers" The devices often considered the first "computers" in our understanding were rather In 1642 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. |

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).

Wide Application Protocol (WAP) The WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including While Internet access has been possible in the past, different manufacturers have used different technologies. In the future, devices and service systems that use WAP will be able to interoperate. Source: Whatis.com |
