ELI5: What is FLOPS and is it a meaningful way to measure a computer's performance?

FLOPS = Floating Point Operations Per Second

It is a meaningful way to measure performance in CPU intensive operations, like computational fluid dynamics.  It's still used some in the super-computing benchmark arena.

It's not a meaningful measure of personal computing performance because most operations in your PC are not complex calculations.  Much of the PC's work is moving data around or operating system activities that are short on complex matrix math.
