* Why larger values?

	bulldozer, wheelbarrow, shovel analogy (moving dirt)
	serial line vs. bus analogy (from EE)

** the von Neumann bottleneck

	Jon von Neumann designed early stored program computer
		[ memory ] =:= [ CPU ]
			   ^this is it: load and store instructions
				1 (or 2) words at a time

** Conceptual bottleneck

	do we have to *think* about moving each word?
		e.g., copying one record to another (in Pascal)

	If language matches computer,
		then assignment of small values, no return of arrays, ...

	example languages: FORTRAN, Pascal, *language of chapter 1*
