not say how.. only to let you know it can be done!

Ok, some general info.
Almost 100% of todays Ethernet topology uses switching technology to
connect their end nodes. Bridges/routers will usually be used to connect
"bigger" networks together or connect a network to the internet (you'll
get it). This is the common topology, but there are many other
possibilities, so this can only be a general answer without knowledge
about your specific network.
Switching means that a normal node (your computer) on that network will
only see the traffic directed to your own node or directed to all
(broadcast) or some (multicast) nodes on the network. As you won't see
the normal traffic of other machines (e.g. the ones containing Google
search strings) --- you're out of luck here.
There are some very bad techniques available to confuse the switches so
you'll see more traffic (but again, these are very bad things that you
shouldn't do).
Hope this helped,
