Although the total number of bytes varies from computer to computer, memory sizes of 65,536 to more than several million bytes are common. In computer language, the letter K represents the number 1024, which is 2 raised to the 10th power, and M represents the number 1,048,576, which is 2 raised to the 20th power. Therefore, a memory size of 640 KB is really 640 times 1024 (655,360 bytes), and a memory size of 4 MB is really 4 times 1,048,576 (4,194,304 bytes). Using this information, calculate the actual number of bytes in the following:
a. A memory containing 512 MB
b. A memory consisting of 256 MB words, with each word consisting of 2 bytes
c. A memory consisting of 256 MB words, with each word consisting of 4 bytes
d. A thumb drive that specifies 2 MB
e. A disk that specifies 250 MB
f. A disk that specifies 8 GB
