title: 8085 assembly instructions MOV, LDA and STA
body: <p>I get the point of <code>MOV</code>, <code>STA</code> and <code>LDA</code> instructions, but what I don't understand is why are there three different instructions for two different processes?</p>
  
  <ul>
  <li><code>STA</code> is for copying data from accumulator to memory location,</li>
  <li><code>LDA</code> is for copying data from memory location to accumulator and</li>
  <li><code>MOV</code> is for copying data between registers plus registers and memory.</li>
  </ul>
  
  <p>So, what I can do with <code>STA</code> and <code>LDA</code> instructions can be done with <code>MOV</code> instruction too, right?</p>
