Lost in packet loss

  Whenever I run a connectivity test there's a field called: "packet loss". Is this an indication of the number of resends on my system?

 

  Thirty five years ago when I was doing 'C' programing. Every data message ( packet? ) exchanged had attached to it a CRC. ( cyclic redundency check ) My program would run a CRC on the incoming messsage, and if the results didn't match the attached CRC, it would send a NAK ( negative acknowledge ) signal to the source, which would then resend the message.

 

  Is this what's meant by a lost packet?

That's essentially it, but I'm sure there are other additonal forward error correcting protocols involved.
