Difference between visit and session

[#1]

Can someone tell me the main difference between session and visit on Omniture? which one should be higher for the same time period?

same as here COMPLETED SESSION

it all depends on how you configure it.

Visits are calculated server side.

Session in calculated client side.

If sessions < 30 minutes then sessions > visits

else if sessions > 30 then sessions < visits

here is an article that I wrote when I was in clientcare Mobile Session Calculation
