Can this be right? Am I missing something?
A professor asked to borrow a couple punch cards to pass around in class. I recently saw an ad for a 1tb drive for eighty bucks, and got to thinking; how high of a stack of punch cards is that?
1,099,511,627,776 bytes, or 1tb
divided by 80 bytes per card =
13,743,895,347 punch cards, times .007 inches, the thickness of a punch card =
96,207,267 inches, divided by 12 inches per foot =
8,017,272 feet, divided by 5,280 feet in a mile =
1,518 mile-high stack of punch cards to equal 1tb.
Really? It just sounds impossible, like I missed a bunch of decimal points somewhere, or made some massive error in logic.
