A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or host, on the Internet.The FQDN consists of two parts: the hostname and the domain name.For example, an FQDN for a hypothetical mail server might be mymail.somecollege.edu. The hostname is mymail, and the host is located within the domain somecollege.edu.n this case, www is the name of the host in the indiana.edu domain. When connecting to a host (using an SSH client, for example), you must specify the FQDN. The DNS server then resolves the hostname to its IP address by looking at its DNS table.
The function key, labeled Fn and located in the lower-left corner of your keyboard, is a useful feature. By pressing Fn along with one of the numbered function keys at the top of the keyboard (F1 through F12), you can adjust your screen brightness, enable and disable your touchpad or wireless modem, lock your computer and complete a variety of other tasks. These keys will not work if the Fn key is not pressed along with them.
