An average American teenager probably recognizes the meanings of about 100 000 words of English. However, this is but a fraction of the total【B9】of information which the teenager has stored.

Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 " words" —ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for ex- ample, the number of faces and places that the teenager can recognize on sight.
The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person' s memory is in terms of words and combinations of words.
