This question is a matter of some dispute, as well as darketing terminology.
When people ask me this question, I answer that they are essentially the
same thing, apart from the way they utilize memory. Routers usually have
"traditional RAM", which allows them to perform very nice things and use it
for buffering, deep packet inspection, stateful firewalls, etc. Switches, at
least Cisco ones, have more constrained memory architecture, which allows
extremely fast switching performance, at the expense of some flexibility.
Of course, things are not that easy, especially with higher-end platforms,
like 6500/7600, which indeed confuse even the best of brains. They are
essentially switches, but when loaded with "WAN" line cards, they are able
to do everything that routers do on those interfaces. Some call them
swouters, I simply consider them schizophrenic and treat them as confused,
disfunctional devices in need of help and understanding.
I guess that with experience, your own definition and understanding of this
darketing terminology will come.
