It is interesting to compare the memory-storage capacity of a computer (57) that of a human being. The instant-access memory of a large computer may hold up to 100000 "words" —ready for (58) use. An average American teenager probably recognizes the meanings of about 100000 words of English. However, this is but a fraction of the total (59) of information which the teenager has stored. Consider, for example, the number of facts 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 (60) of words.
