Document Summary

Comp (cid:1007)(cid:1004)(cid:1004)(cid:1008) lecture (cid:1005)(cid:1004): architectural: no silver bullet guest lecture, orders of magnitude. Styles: orders of magnitude are used to make approximate comparisons. If numbers differ by one order of magnitude, x is about ten times different in quantity than y. Liberate the developer of the low level computer instructions (registers, buffers, interruptions, clock cycles, cylinders: the developer can think in higher level structures like data types, operations or sequences without thinking in the low level concepts. Invisibility: software is invisible and unvisualizable, it is not inherently embedded in space. The (cid:373)ass p(cid:272) (cid:373)arket has (cid:271)roadened the market for software, now building custom software is not the only option: e(cid:454).
