title: Converting from 1Mbyte to Hex
body: <p>I am having problem understanding the following text,</p>
  
  <blockquote>
    <p><code>8088</code> supports <code>1</code> Mbyte of external memory. This memory space is
    organized from a software point of view as individual bytes of data
    stored at consecutive address over the address range <code>00000</code> to <code>FFFFF</code>.</p>
  </blockquote>
  
  <p>Now I don't get how the author converted from 1 Mbyte to FFFFF. Can anyone please help me out?</p>
  
  <p>Thanks.</p>
