Mohamed,
1) Fast switching is the default for everything except IP. Optimum
switching is the default for IP.]
2) Process switching is the most CPU intensive because the router has to
processes every packet, no caching of anything. Some debug commands can
actually overload a somewhat busy
Optimum switching is the default only on platforms that can use it.
Lower-end routers like the 2500/2600/3600 can't do optimum. In those
cases, fast switching is the default.

You are correct sir. What's interesting is that the CIT book doesn't
mention that detail. It just says Optimum is the default (I guess it is
talking about 7500's tho). When studying this, I went to Cisco's site and
read up on this to be sure.. It seems now (on units that support it)
CEF
I'd like to know which is the default switching in Cisco Routers for TCP/IP
traffic? Is it Process or Fast Switching?
Also there're some questions I need an answer to:
1- When issuning debug commands,do I need to turn off Fast Switching ?
2- Which leads to more CPU and Memory utilization:

Hi Debbie and all!
Is one of theses switching methods the same as the Cisco Express
Forwarding (CEF)?? If not, what are the differences between them and, most
important, what do I loose on enabling it?
