Explanation / Answer

1. We require a global configuration mode to configure a switch
switch# configure terminal // after this it comes to config mode as listed below
switch(config)#

2. We require Interface Configuration Mode to configure the ports.
Router(config-if)# interface type number // after this it will go to interface as listed below
Router(config-if)#

But if you want to configure it in more details then you need to use Subinterface Configuration Mode
From a bridging spanning-tree viewpoint, each subinterface is a separate bridge port, and a frame arriving on one subinterface can be sent out on another subinterface.
Router(config-if)# interface serial 2.1 // after this it will go to sub-interface as listed below
Router(config-subif)#

3. For initial configuration of router through terminal we use the rj45 port that we connect to the CPU so that we can use that CPU as terminal for the router. Then to frame the network we connect to the variuos ethernet ports available in the router, they are also said as Fast ethernet ports often.
4. The sh ver is the short form of show version it displays results like
For Example:
switch# show version

5. The sh flash is used to display the contents of Flash memory
For Example:
Router#show flash
24576K bytes of processor board System flash (Intel Strataflash)
Directory of flash:/
2 -rwx 18929780 Aug 29 2006 15:49:57 +00:00 c870-advipservicesk9-mz.124-15.T5.bin
3 -rwx 2181 Oct 4 2006 04:03:00 +00:00 mybackup-today
23482368 bytes total (4544512 bytes free)

difference between show flash command and show version command
- In both cases the size of processor board system flash (read/write) is
shown a bit different that is what I think.
