      1- what is protected mode?
      2- What is a real address mode ?
      3- What is the term 'Physical Memory' Means?
      4- what does the 'supporting chips' mean?
      5- And basically what these paragraphs means
      6- How to locate the Segment:offset address which is also known as
      the Logical Address?
      for example
      A4FB0h
      +4872h
      ________
      A9822h
      How this is calculated?
      More addressable memory:
      The 80286 in protected mode can address 16MB of physical memory as
      ooposed to 1MB 8086 and 8088 microprocessors.

      Virtual Meomory in the Protected Mode:
      This means that the 80286 can treat the external storage as if it
      were physical memory, and therefore execute programms that are too
      large to be contained in physical memeory, such programmes can be
      upto 1 GB.
      Pls reply soon
      Best Regards
