<1> Linux system CPU load average checking:

     |__ $ uptime
	 
             18:08:04 up 73 days,  4:48,  4 users,  load average: 2.45, 1.97, 1.18
                                                                 -----  ----- -----

                                                                   |      |_______________ Load average in last 05 minutes.

<2> Traffice Analogy: 
    |
    |__ CPU is the road, and each car presents one slice of processes

		
     >> Load average = 0, CPU = 1
