Differences/Similarities between a Pix unit (501) and an ASA

Buck Rogers · Guest

Hello,

I'm trying to get a handle on the similarities and/or differences
between a PIX (501) unit and an ASA unit (5505).

I have limited experience using and configuring the Pix 501 through
two small businesses I support and was looking to expand my knowledge.

Is there a Cisco article that compares the two (PIX vs an ASA unit)?
Or are we talking apples and oranges?

Regards

Buck
