There are five passwords used to secure your Cisco routers: console, auxiliary, telnet (VTY),enable password, and enable secret. Just as you learned earlier in the chapter, the first two passwords are used to set your enable password that’s used to secure privileged mode.

NFS was developed at a time when we weren’t able to share our drives like we are able to today – in the Windows environment.
