Below would be the super base essentials you need before you even begin to use a Router or Switch. No.. I'm not a geek. Nope not at all. Don't forget to fix the exec timeout once your done.
en (enable)
conf t (configure terminal)
lin c 0 (line console 0)
exec-t 0 (exec-timeout 0)
logg s (logging synchronous)
exi (exit)
no ip domain-lo (no ip domain-lookup)
