biotechnology summary The fusion of flesh and machine is trend which, although inscribed in the history of modern technology from its beginnings, has reached a unprecedented momentum in recent years as a result of crucial advances in information technology, biology, and the development of global networks. Consequently, doubts are emerging concerning the viability of a distinct and definable human nature. Historical and social theories and concepts are being unhinged by the spread hybrids and by new forms of artificial life which are likely to trigger social changes escaping the grip of calculation. Attempts to defend an essential human nature against technical hybridisation, rather than strengthening the human subject, may have further blurred the question of historical subjectivity. Large amounts of money are invested into research and development of artifical biology, making some of the predictions of AI and robotics experts about radical and far reaching changes a matter of time. |

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).
