Well Known Ports:
IANA assigns TCP and UDP port numbers to specific uses. The port numbers are
divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or
Private Ports.The Ports that are popular (well known) are those in the range 0–1023.
WINS:
Windows Internet Naming Service. This is part of the Microsoft Windows NT Server. It
manages the association of workstation names and locations with Internet addresses. The user or an
administrator does not have to be involved in each configuration change.
X
XFS:
A high-performance journaling filesystem created by Silicon Graphics for their IRIX operating
system. XFS has been merged into the mainline Linux 2.4 and 2.6 kernels, making it almost
universally available on Linux systems. Installation programs for the SuSE, Gentoo, Mandriva,
Slackware, Zenwalk, Fedora, Ubuntu and Debian Linux distributions all offer XFS as a choice of
filesystem. FreeBSD gained read-only support for XFS in December 2005 and in June 2006
experimental write support was introduced to FreeBSD-7.0-CURRENT.
Z
Zeroconf:
An IETF (Internet Engineering Task Force) specification that lets IP network devices
automatically configure themselves and be discovered without manual intervention. Zeroconf can
also manually assign an IP address and alternate host name to a device, as required. Once
assigned, Zeroconf lets users and applications readily discover the service it offers. Apple’s Bonjour
is the major implementation of Zeroconf.
