I was reading a magazine, and at one point the article compared a number
of computers (Hypercubes, parallel and various architectures) by listing
different speeds.  I understand that all computers have clocks that run
at different speeds or cycles (Mhz...etc).  But the article was using
terms like  Mips, Mops, Mflops.  Discarding the M as Mega, 

	ips = instructions per second
	ops = operations per second
	flops = floating point operations per second 

I was wondering how these items relate to clock speed.  I understand
that if you have a 16Mhz clock, you don't have 16Mips...etc.  

Can anyone help me figure out the difference among these quantitative 
descriptions?
