Hi i'm just learning computer networks and i have learned about windowing in tcp

And my question is does we determine connection speed using windowing?

I mean computer know the number of packets and also the size of each packet

So number of packet * size of packet in 1 second can be our connection speed right?

Can anyone help me?

No, that is usually called "throughput."

The connection speed is determined by the clock rate (i.e. bandwidth) of the physical circuit. It's a fixed value based on the hardware and never changes.

  • If network connection is fixed value why out internet speed change ? – Mohammad Ansari Oct 27 '19 at 13:19
  • Because throughput can change based on network or traffic conditions. – Ron Trunk Oct 27 '19 at 13:46
