      OSI or ISO
       The layering model is OSI, which stands for 
         Open System Interconnection.
       The organization that developed the model 
         is ISO,  International Organization for 
         Standardization. 
           ANSI (American National Standards Institute) is a 
            member of ISO.
             ANSI farms out much of the hardware 
                standardization to the IEEE.

     ISO
      International Organization for 
        Standardization, shouldn’t that be 
        IOS???
      No.  ISO is not really an acronym. 
      “ISO” was chosen because it means 
        equal as in an isosceles triangle that 
        has two equal sides.
     CSIT 220 (Blum)                                   3
     Standards
      “Standards are documented 
        agreements containing technical 
        specifications or other precise 
        criteria to be used consistently as 
        rules, guidelines, or definitions of 
        characteristics, to ensure that 
        materials, products, processes and 
        services are fit for their purpose.”
      From the ISO website

      Open versus Proprietary
       Open: specifications are public.
             Requires committee agreement, can be slow.
       Proprietary: Privately owned and 
          controlled, specifications are kept private so 
          that other companies cannot duplicate.
             No outside agreement needed, can be reactive 
              (faster). 
       Consumers prefer open and standardized 
          systems, as these allow them to use the 
          products of various manufacturers. 
             But sometimes it takes too long to come up with 
              them.
