Chapter 2.3, Problem 9E

(Practice) Although the total number of bytes varies from computer to computer, memory sizes of millions and billions of bytes are common. In computer language, the letter M representsthe number 1,048,576, which is 2 raised to the 20th power, and G represents 1,073,741,824, which is 2 raised to the 30th power. Therefore, a memory size of 4 MB is really 4 times 1,048,576 (4,194,304 bytes), and a memory size of 2 GB is really 2 times 1,073,741,824 (2,147,483,648 bytes). Using this information, calculate the actual number of bytes in the following:

a. A memory containing 512 MB

b. A memory consisting of 512 MB words, where each word consists of 2 bytes

c. A memory consisting of 512 MB words, where each word consists of 4 bytes

d. A thumb drive that specifies 2 GB

e. A disk that specifies 4 GB

f. A disk that specifies 8 GB
