title: Different Segments may collapse with each other
body: <p>When we code, then we give different segment registers the same value, in that case the two different segments may mess up with each other, and the problems may arise. 
  For example in below given condition. </p>
  
  <pre><code>MOV AX, CS
  MOV SS, AX
  ASSUME SS: DOSGROUP 
  </code></pre>
  
  <p>as mentioned in above lines, in line 1 we move CS to AX. Immediately after it we AX to SS. This means at this point CS and SS registers are containing the same value or same memory location, Is'nt that true that when we code further, the contents of CS will collapse with the contents SS. </p>
