Lets Unix users exchange information.
A modern computing facility consists of one user per host, and many hosts per site. To find out about logged on users at another site you must query each host to find out about an individual user. With GNU Finger, a single host is designated the finger "server" host and collects information about who is logged on to other hosts at that site. A user then needs to query only the server host, instead of each host at that site. GNU Finger follows the finger "protocol" (rules for communication) in responding to simple requests, since this protocol is simple. But it can also implement another protocol that lets two finger programs exchange information in a predetermined way; this allows faster and wider bandwidth communication.
