3.The quality of the graphics output on a computer printer is measured in dpi (dots per inch). Simply by changing the density of dots that make up peach part of an image, the printer can produce graphics that look almost photographic. To understand how this works, consider how a black-and-white photograph shows the shades which, in real life, are colors. Each color is a different shade of gray, For graphics to be produced on the computer printer, a piece of software called a printer driver decides upon a dot pattern which will represent each color shade.

4. The Library of Congress in Washington, D.C., which houses the largest collection of books in the world, is fighting a battle against paper deterioration, The pages of old books, often yellowed and torn, sometimes crumble when they are touched, The main culprit in the battle is the acidic paper that has been used for making books since the nineteenth century. Air pollution and moisture have added to the problem. Strangely, the books that are most in danger of destruction are not the oldest books.
