If you used only a keyboard to enter data, how many years would it take to fill up the hard drive in a computer that can store 1.6 terabytes (1 terabyte = 1.0 * 1012 bytes) of data? Assume 40-hour work weeks, that you are typing 50 weeks in a year, and that you can type 180 characters per minute, and that one byte is one keyboard character.

74,074 years.

Explanation:

1 tb is equal to 1,000,000,000,000 bytes.

1.6 terabytes is equal to 1.6 x 1,000,000,000,000 = 1,600,000,000,000‬ bytes.

40 hour work per week and 50 weeks in a year means the person is typing 40 x 50 = 2,000 hours per year.

2,000 hours is equal to 2,000 x 60 = 120,000 minutes.

Characters typed per year, based on speed of 180 characters per minute, is equal to 180 x 120,000 = 21,600,000 characters.

21,600,000 characters per year = 21,600,000 bytes.

It would take approximately 1,600,000,000,000 / 21,600,000 = 74,074 years to fill up the hard drive.
