THE COMPUTER

The computer is basically a device for ingesting, judging, and otherwise

processing or usefully modifying knowledge. Thus it enlarges brainpower in the

same way that other man-made machines enlarge muscle power. Like man, the

computer expresses knowledge in terms of symbols; man's symbols are letters and

numbers, and the machine's symbols are electromagnetic impulses that represent

letters and numbers. Although man must usually instruct or program the machine

minutely, its chief present advantage is that it can manipulate symbols a million

times faster than a man with pencil and paper, and can make calculations in a few

minutes that might take man alone a century. An expert has remarked that the difference between doing a calculation by hand and by computer is the difference between having one dollar and having a million. Sometimes the difference is

infinite; only a computer can calculate swiftly enough to analyze the data from a satellite, or to enable man to control the flight of a missile.
