User Exec Mode (distinguished by the ">" prompt) is your first mode and it is also called enable mode , which is used to get statistics from router.
Router>?Exec commands:
<1-99> Session number to resume

Privileged Mode (distingushed by the "#"
prompt) is the second mode. Here you can enable or disable interfaces
on the router, get more detailed information on the router, To come to privileged mode type the "enable" command in the user mode.
Router>enable
Router#
Global Configuration Mode (distingushed by the (config)# prompt) is accessable via Privileged Mode.
In this mode you're able to configure each interface individually,
- setup banners and passwords,
- enable secrets (encrypted passwords),
- enable and configure routing protocols
- etc...
We dare say that
almost everytime you want to configure or change something on the
router, you will need to be in this mode.
Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
there are steps which shows how to configure a router
