Stop spamming the forum with single-topic threads. Put all your questions in one big thread.

Specify the purpose of the questions if they are for school work or otherwise. The reason behind this are two-folds:

1. A professor or instructor can tell if the answer is copied somewhere and may he/she might find ways to verify if you are a "hidden genius" or a plagerist.

2. What happens in the "wild" and what happens behind text books are two different things: Text books might give you what happens in an "ideal world" and this is what the instructor wants. If he/she finds answers that do not comply with text book materials one might not like the grades handed back.

BTW, there's more than those 3.

On modern Cisco L3 switches, they likely support CEF, in hardware.

Not sure if it's considered "switching", but there's also flow cache to accelerate packet forwarding.

There's also distributed switching.

Also, although I assume you're asking about unicast, much of this applies to multicast too:

BTW, from just these two references, there's much to be found searching Cisco's main site. Questions like these are better answered in Cisco's Learning Forums.
