Internet activity tracking

[jjpp12]

What can a server/ISP tell about your internet activity from the following? Is it enough to reconstruct activity in depth?

source and destination IP address
source and destination port numbers
protocol type
number of octets of data
number of packets of data

Hmm...and why would you need to know this?

However with the destination IP you should be able to find out rather easily.
