Simple Fundamental Algorithm Question, binary tree traversal
<p>I'm trying to explain to non-computer science major student with many questions.</p>

<p>(1)What traverses tree? Is it just logic or actual on off switch generates 1s and 0s traveling the circuit board? where is this tree and node exists CPU/Memory in between?</p>

<p>(2)If it is 1s and 0s HOW the circuits understand the line for example p=p.getLeft(); </p>

<p>I said search the google or wiki. </p>
