Question

A certain CD-ROM disk can store 600 megabytes of information. If an average word requires 9.0 bytes of storage, how many words can be stored on one disk?

Answer 1

6.6667 x 10⁷ words

Explanation:

In the decimal system, there are 10⁶ bytes in a megabyte. Thus, the CD-ROM disk can store 600 x 10⁶ bytes of information. If each word requires 9.0 bytes of storage, the number of words that can be stored on one disk is given by:

`n = (600*10^6)/(9.0) = 66.667*10^6 = 6.6667*10^7\ words`

The disk can store 6.6667 x 10⁷ words or roughly 67 million words.
