“your current net fast is: What concept 3469.12 is Kbps”? Quick? Slow?

I in the net which on-line measured fast did not know that is any concept! Looks under person explanation which knew.Thanked!
Is 3.4M each second.Very quick.Is the 3M meaning, generally the family user is 2M… Very good already 512Kbps, downloads the speed to be able actually to achieve about 60k/s.
1Mbps, downloads the speed to be able actually to achieve about 120k/s.
2Mbps, downloads the speed to be able actually to achieve about 240k/s.
what meanings kbps and are KB?
Should be 1KB=9kbps (1byte=8bit+1stop bit), but to calculate conveniently, generally thinks 1KB=8kbps.
Under the estimate your downloading speed is 450 about ~~, if perhaps you are the first test speed do not permit to test many times look at the mean value 3469.12/8bit = 433.64B/S = about limit 432KB/S Good Slow English question:
kbps is kb per second may also understand is kb/s, the kb/second
Is each second Kb size
3M each second
Very quick
The regulating words should also have 400K each second
