Skipping some details, a process is either sleeping (waiting for
some resource or event and thus not runable), runable but not
running (all resources and events satisfied but not yet in the
cpu), or running (in the cpu). Load is the number of processes
that are running or runable, i.e. how many are using or could
use the cpu.
Note, if you have multiple cpus (or cores) an acceptable load
average is higher. I.e. for a 4-cpu system, a load average of
4 would be similar to a load average of 1 for a uni-processor.

If not installed, the similar /usr/bin/prstat is standard.
