Showthat the combined capacity of several (two or three) modern disk storage systems, such as the EMC Symmetrix System that stores more than nine terabytes (9 × 10¹²
bytes) [EMC Products-At-A-Glance, www.emc.com], could contain all the 26 million texts in the Library of Congress [Web search, Library of Congress].

(a) Assume that the average book has 400 pages

 (b) Estimate the number of lines per page by counting lines in three different books.

 (c) Repeat (b) for the number of words per line.

(d) Repeat (b) for the number of characters per word.

(e) Use the above computations to find the number of characters in the 26 million books. Assume that one character is stored in one byte and calculate the number of Symmetrix units needed.
