Priority Queue applications
<p>What are the computer applications of priority queue data structure ?I want to know about the computer processes or computer applications which make use of priority queues. I know one such application. We can use priority queue in the printer buffers. For example, suppose there are 3 priority levels. The user needs to specify his/her priority before giving the printing command. So the document in the buffer with highest priority will be printed first and so on.</p>

<p>So any other applications of this kind?</p>
