1. Recall that a punch card can store 80 bytes, and that 133 punch cards measure 1"x7.375"x3.25". I went to Best Buy the other day and found a 4TB drive that measured 3.5"x2.3"x0.5".
   1. How many bytes per cubic inch can you store on punch cards?
   2. How many bytes per cubic inch can you store on the drive from Best Buy?
   3. How many punch cards are required to store 4TB?
   4. How much space (in cubic inches) is required to store 4TB on punch cards? Convert your answer to cubic feet so it is easier to comprehend (1 cubic foot is 1728 cubic inches).
   5. How much more efficient, in terms of space, is the Best Buy drive than punch cards?
2. Find a reputable source to help answer this question: Are 5G, 5GHz, and 5Gbps the same thing? If not, what does each mean and are they related to each other? For full credit, be very precise/specific in your answers, but also be concise! Also, include your source(s) in your solution.
