What do the green bars next to players' names in the 'tab' window mean?

When I push TAB on Minecraft servers it comes up with a little green connection bar next to the players' names!

What does this mean?

It represents how good each player's latency (ping) to the server is. The fuller the bars, the lower (and better) the latency.

The green bars represent the strength of a player's connection to the server.

It's the player's internet connection, it's like a WIFI bar; it describes what players are online.
