Kevin Warwick at the University of Reading works on implant technologies which could enhance or modify functions of the limbs and the brain, or bring back functionalities lost, for example, in an accident or as a consequence of a stroke. Implants are also used for identification in "intelligent buildings" where they serve to control "personnel flows". However, the real potential of electronic implants seems to lie in the field of electronic drugs. The basics of the brain computer interface are already explored, and there are now efforts to electronically modify the function of the mind. Large software and IT companies are sponsoring this research which could result in the commercialisation of electronic drugs, functioning as anti-depressants, pain killers and the like. Evidently, the same technologies can also be used as narcotic drugs or to modify people's behaviour. The functioning of body and mind can be adapted to pre-defined principles and ideals, their autonomous existence reduced and subjected to direct outside control.

Caching is a mechanism that attempts to decrease the time it takes to retrieve data by storing a copy at a closer location.
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

The U.S. Data Encryption Standard (= DES) is the most widely used encryption algorithm, especially used for protection of financial transactions. It was developed by IBM in 1971. It is a symmetric-key cryptosystem. The DES algorithm uses a 56-bit encryption key, meaning that there are 72,057,594,037,927,936 possible keys.
