The volume of the abstract is approximately 16 KB (the computer alphabet is 256 characters)

The volume of the abstract is approximately 16 KB (the computer alphabet is 256 characters), the print speed on a dot matrix printer is 64 characters per second. How many minutes will it take to print this text on such a printer?

The number of characters in the alphabet is 256 = 28, which means one character is encoded in 8 bits.

16 KB = 16 * 2 ^ 10 * 2 ^ 3 Bits = 217 Bits

This means that the total number of characters in the abstract is 2 ^ 17/8 = 2 ^ 14 = 16384.

The printer prints at 64 characters per second.

This means that he will print the abstract in 16384/64 = 256 s.
