There's a whole pile of things that could be network activity, but you really want to do something like "netstat -atuevp" to see what, where, and who is involved in network traffic.

launched since powering up
Run "gnome-session-properties" and see what's enabled. There's often more than you need preconfigured to start, and turning off some junk can make logins quicker to complete.
Do you have apps that show you the weather, calendar appointments?
Is the clock using NTP to correct itself? Which is a good idea, by the way. At start-up it does a bit of checking, then it gathers data less often the longer it's running. Chrony is probably simpler, traffic- wise, but I found it unsuitable for machines that are left running.
You probably have Avahi/ZeroConf/Bonjour running, which looks for printers and other internet-of-things on your network. Likewise, if you have IOT gizmos at home, they're probably probing your computer, too.
