Computer sending out data

[bob616]

I just got a macbook pro and I installed istat in the dashboard. I noticed that my computer is sending out a lot of data, for example istat says that it is sending out 35 kbs with a total of 258 for today. My question is what is my computer sending out and should I be worried?

Every time you request a page from the internet, or an app checks for updates, it sends data.

You can get Little Snitch to see what apps are sending the data.
