Introduction: The Substitution of Human Faculties with Technology: Powered Machines The development of the steam engine in 1776 represented a major advance in the construction of powered machines and marked the beginning of the Industrial Revolution. Powered engines and machines soon became common and led to the first extensive mechanization of manufacturing processes. The development of large-scale machine production on one hand decreased the demand for craftsmen and increased the demand for semiskilled and unskilled workers and on the other altered the nature of the work process from one mainly depending on physical power to one primarily dominated by technology.

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).
