What does we mean by Connection View?

[QAnts]

Hi All,

I tried to test my web page with this tool and I got two tables based result. One is showing the waterfall view and another is showing connection view.

Waterfall view is showing the components download sequence and connection view is showing the connection. My questions are:
a) What does this connection view describe?
b) Why all the components are not showing connection time but most of them are showing connection time?
c) How can we reduce these # of connections?
d) How can we reduce the connection time of a component?

Looking forward for your kind help.

Regards,

Zaman
