This is where I work on drafts.
For centuries, people sought assistance from mechanical devices in performing onerous arithmetical calculations (ref. abacus and knotted string--Amer. Indians?, and of course the slide rule).
The invention of computers--electronic machines that can perform numerical manipulations far faster than humans--revolutionized the world in the later half of the the twentieth century.
The first generation of computers (1940's and 1950's) were in fact used primarily for performing complex mathematical calculations such as actuary tables or weapons firing trajectories. As the complexity of computer hardware increased, an even more drastic revolution occurred in the programs which the hardware was able to execute.
The classical, most stripped-down view of a computer has the following four basic parts:
processor (and bus)
memory
input (punched cards? keyboard? mouse? microphone?)
output (printout, monitor, sound, industrial automation of mechanical robots)
Although today's computer are used as a tool in almost every profession, in the early years after their inventions, computers were the domain of scientists, mathematicians and engineers.
Discuss the notion of a programmable computer, or a stored-program computer, and the Church-Turing ideas.
Summarize the state of computing today without listing ten thousand computing jargon words.
Outline the growth of a new academic discipline, computer science, starting around 1980's, and the parallel growth of world-wide computer networks. Mostly this part should just point off to other articles (that's where the jargon can live).
