title: Is the point of multi-threading to increase your CPU usage?
body: <p>I am very new to the concept of multi-threading, but to my understanding the whole point of multi-threading architecture (I learnt there is hardware multi-threading and software multi-threading; not that I completely understand the concept of each but I think I am talking about the hardware aspect here) is to "keep your CPU busy". This is for example to process another task when your current one is fetching your hard-disk for data import. </p>
  
  <p>If I am correct, for a non multi-threading CPU, if it already has near 100% usage, then switching to a multi-threading one would not help you much. Am I correct?</p>
  
  <p>I am sure my statement of the problem is full of inaccuracy but I hope I made myself understood.</p>
