How many years will it take to occupy the computer's hard drive that can store data of 82
gigabytes if you used the keyboard to input data? Assume "standard" 8-hour working days, and that one byte is needed to input one keyboard character, and that you are capable to type 180 characters per minute.
If you used only a keyboard to enter data, how many years would it take to fill up the hard drive in your computer that can store 95gigabytes95gigabytes (95×109bytes95×109bytes) of data? Assume "normal" eight-hour working days, and that one byte is required to store one keyboard character, and that you can type 180 characters per minute.
Express your answer using two significant figures.

- A firm has a computer, which it uses for a variety of purposes. One of the major costs associated with the computer is software development. The vice president for information systems wants to evaluate whether it is less costly to have his own programming staff or to have programs developed by a software development firm. The costs of both options are a function of the number of lines code (program statements) the vice president estimates that in-house development costs $1.50 per line of code. In addition, annual overhead costs for supporting the programmers equal $30,000. Software developed outside the firm costs, on average, $2.25 per line of code. (a) How many lines of code per year make costs of the two options equal?(b) If programming needs are estimated at 30,000 lines per year, what are costs of the two options?(c) In part (b) what would the in-house cost per line of code have to equal for the two options to be equally cost?arrow_forwardThe rhinovirus which causes the common cold has a diameter of 30 nm.
