I felt good pride when I figured out what a binary numbering system is, computers use it plus it makes a lot of sense because it simplifies everything down to more than 2 choices! Things are either on or off or given a value of zero or a singleâ€¦ When you do a simple task of counting, zero is zero, a single is a single, more than 2 becomes 01, more than 2 becomes 10, more than three becomes 11, more than 2 becomes 101, plus so on. With complex problems, the computer plays an expanded version of “20 questions” answering more than 2 questions with a no or yup to calculate the answerâ€¦ It would indeed be a boring world if everything was a binary systemâ€¦ Rainbows would be a black stripe against a colorless sky. There would be no “door number multiple” on game shows unless they renamed it as door number 10. Those in the LBGTQ+ community would be out of advantage because the more than 2 gender identification labels would revert to the original multiple. Thankfully, unlike humans who engage in an almost infinite number of non-binary activities, there is Heating, Ventilation & A/C with its binary purposes of heating plus cooling our indoor environments. To keep those Heating, Ventilation & A/C units running at top efficiency more than 2 yup or no questions must be answered, but do Heating, Ventilation & A/C filters need to be replaced frequently? The answer is yup. If an Heating, Ventilation & A/C system does not undergo usual cleaning plus service, will it eventually split down? Again, the answer is yup, one question has an emphatic no answer. That question is: Should I perform Heating, Ventilation & A/C repairs as a DIY project? If you do, it could result in another sizable no answer when you file a claim against a warranty that has been voided by your reluctance to use a qualified Heating, Ventilation & A/C professional to repair your binary Heating, Ventilation & A/C unit.
