Example text

Software must generally be buttressed by mechanisms depending on quite different technologies that provide robust forms of diversity. S. 1 This Boeing 777 could not be flown commercially without near-unimaginable reliability in its flyby-wire control system. ) Clearly, the most critical technology in the application of fly-by-wire is a means of assuring reliability. When the NASA Flight Research Center team made the decision to go digital, it entered a world plagued by finicky hardware and untrustworthy software.

The log-scale slide rule, once the dominant personal computing device, is an analog computer. , that it is used to calculate. Another type of mechanical analog computer was the differential analyzer, which was in scientific use from the early 1930s through the early 1950s (and was one of the lesser known “stars” of the film When Worlds Collide). The “DA,” as it was called, had cams of various shapes to model the terms of equations. The analyzer filled a goodsized room and had to be operated by hand.
