No, TCP is designed to HANDLE packet loss. Nothing* will PREVENT packet loss. Somebody clearly doesn't deserve his diploma Razz

(*nothing reasonable, anyway)

My understanding agrees with Kllrnohj, TCP is built on top of a best effort network which means that packets can be lost by the underlying technologies, however TCP prevents the layers build on it from seeing it by resending the packet until it gets through so no packet is permanently lost. Also I was under the impression that it would use a ICMP ping which is what I assume it was doing given the permission warning I got when I ran it. An ICMP ping is on the same level as UDP and TCP if my quick reading is right which would allow it detailed access to packet loss and other network statistics without being messed up by a retransmission. Why did you think it was TCP?

EDIT: I missread, it is below TCP and UDP on the internet layer below the transport layer where TCP and UDP are.

It uses a Java applet to test packet loss, which you need to approve first (and probably rerun the test to get rid of the prompt). That said, I don't think something's quite right in the way they test it:
