Our cable cost is up again, though I have an explanation. Recently I added a converter box to my office to allow me to use my HD TV in HD. What a concept!
I began to look through the bill and was surprised to see how much it costs to rent our cable modem–$7 per month! The exclamation point is there because buying the very same model runs between $50 and $60 at retail. Comcast has to get a much better deal.
Years ago we had trouble with a cable modem. This was rental meant as a temporary solution though it somehow became permanent.
I went online and bought a modem of my own. It’s a DOCSIS 3.0 version from Motorola providing a little future proofing! It will pay for itself in less than a year.
Tonight I called Comcast to light it up. I prepared for the call by jotting down the 12 digit MAC number.
A one and three zeros is a thousand. A one and twenty four zeros is a septillion (1,000,000,000,000,000,000,000,000).
According to the University of Hawaii:
There are seven quintillion five quadrillion grains of sand on all the beaches of the world. That’s a 75 with 17 zeros following! (7,500,000,000,000,000,000)
In other words the serial number schema from Motorola is large enough to give each grain of sand on Earth its own number with plenty of room to spare! In fact the entire grain-of-sand catalog would make such a small dent in the available bank of numbers it’s tough for me to explain. Let’s just say it hardly makes any dent at all.
Motorola — why do we need numbers this large? What are you trying to prove?
