I&#x27;d also recommend &quot;How the world was one&quot; ( <a href="http:&#x2F;&#x2F;www.amazon.com&#x2F;How-World-Was-Arthur-Clarke&#x2F;dp&#x2F;0553074407" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;How-World-Was-Arthur-Clarke&#x2F;dp&#x2F;0553074...</a> )<p>It does an astonishingly good job of describing how networks evolved and why the function as they do today (as of mid-90&#x27;s - not much has changed AFAICT).
