The only biometric technology which does not measure the visual features of the human body. In voice recognition the sound vibrations of a person is measured and compared to an existing sample. The person to be identified is usually required to pronounce a designated password or phrase which facilitates the verification process. Voice recognition can be used on the phone, but has the weakness of technology is its susceptibility to interference by background noise.

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.
The most different institutions with various interests in their background work in that field; not rarely paid by governments, which are interested in inhabitants, connected to the net and economy.

English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits. One of the first Englishmen to write on logic, Boole pointed out the analogy between the algebraic symbols and those that can represent logical forms and syllogisms, showing how the symbols of quantity can be separated from those of operation. With Boole in 1847 and 1854 began the algebra of logic, or what is now called Boolean algebra. It is basically two-valued in that it involves a subdivision of objects into separate classes, each with a given property. Different classes can then be treated as to the presence or absence of the same property.
Also called microcircuit, the integrated circuit is an assembly of electronic components, fabricated as a single unit, in which active semiconductor devices (

English mathematician and inventor who is credited with having conceived the first automatic digital computer. The idea of mechanically calculating mathematical tables first came to Babbage in 1812 or 1813. Later he made a small
