Real-Life Math -- Solution
A. How many additional gigabytes of Internet traffic will
this feature generate on your servers if 75 percent of your users download
the ANON feature?
Gigabytes = 75% x 100,000 users x 275 MB / 1,024
MB per GB
Gigabytes = 0.75 x 100,000 users x 275 MB / 1,024 MB
per GB
Gigabytes = 75,000 x 275 / 1,024
Gigabytes = 206,250
/ 1,024
Gigabytes = 20,142
B. If the partner
wants $250,000 for the ANON feature and Internet traffic bandwidth costs $2
per GB, how much will this deal cost in total?
Cost = $250,000 +
(20,142 x $2)
Cost = $250,000 + $40,284
Cost = $290,284
C.
If the average user connects to the Internet with a modem that can transmit
data at an average rate of 150,000 bytes per second, how long will it take
the average user to download the new ANON feature?
Time
= 275 MB x 1,024 K per MB x 1,024 bytes per K / 150,000 bytes per second
Time
= 275 x 1,024 x 1,024 / 150,000
Time = 288,358,400 / 150,000
Time
= 288,358,400 / 150,000
Time = 1,922.39 seconds
What
is that in minutes?
Minutes = 1,922.39 seconds / 60 seconds per
minute
Minutes = 32.04
"I really haven't used math
much in privacy other than budgeting... of your resources for your office,"
says CPO Merri Beth Lavagnino. "And statistics -- we do a lot of statistics
when we do what we call 'metrics.' (Measuring some aspect of an organization's
activities.)
"In order to justify something, you might need to do
some metrics, but typically you're getting those metrics from a person operating
a service for you," Lavagnino adds.
