A client program that allows a
user to navigate the Internet World Wide Web through hypertext links.
These links, called uniform resource locators (URLs), specify the protocol,
location, and file name of each document. The documents can be text,
graphics, video, or audio. The links can also use other protocols such
as File Transfer Protocol (FTP).
Web page
A Hypertext Markup Language (HTML)
document that can be accessed by a uniform resource locator (URL) on the World
Wide Web. Contrast with home page.
well-known port
In the Internet suite
of protocols, one of a set of preassigned protocol port numbers in the range
1-1023 that address specific functions used by transport-level protocols
such as the Transmission Control Protocol (TCP) and the User Datagram Protocol
(UDP). For example, File Transfer Protocol (FTP) uses well-known
port 21, Trivial File Transfer Protocol (TFTP) uses well-known port 69,
and Hypertext Transfer Protocol (HTTP) uses well-known port 80.
well-formed
A term used to describe an XML
document that follows the basic rules for writing XML markup language.
These rules include, but are not limited to the following:
All tags must be opened and closed. XML also allows you to write
empty elements by adding an ending slash before the closing bracket; for
example, <address />.
Tags must follow nesting rules.
Either single quotations (' ') or double quotations (" ") must
surround the value of an attribute.
Go to the XML specification on the W3C Web site at http://www.w3.org/ for more specific
information about well-formed documents.
WGTA table
A TPF control table that serves
as the focal point for the system records associated with unique
terminals; namely, the agent assembly area (AAA) and the routing control
block (RCB).
white space
Space characters, tab
characters, form feed characters, and new-line characters.
wide area network (WAN)
A network that
provides communication services to a geographic area larger than that served
by a local area network or a metropolitan area network and that may use or
provide public communications facilities.
wide-oriented file
A file stream that
contains only multibyte characters.
wildcard address
When a socket address is
specified as INADDR_ANY, the system interprets the address as any
address. If the caller of a bind function specifies the
internet address as INADDR_ANY, the socket is bound to all network interfaces
on the host.
wildcard character
A special character, such
as an asterisk (*), that can be used to represent one or more
characters.
working directory
The active directory used
to resolve path names that do not begin with a slash (/). A working
directory can also be referred to as the current directory or the current
working directory. A directory, associated with a process, that is used
in path name resolution for path names that do not begin with a slash.
(POSIX.1) Synonym for current directory, current
working directory.
working storage
Refers to those areas of
main storage that are (1) available to application programs as system
resources and (2) the system control blocks used for managing an entry.
Contrast with fixed storage.
World Wide Web Consortium (W3C)
A body that
makes recommendations for standard Web specifications. The W3C
developed the DOM specification and the technology behind namespaces and
schemas (DTD and XML Schema). For more information, go to the W3C Web
site at http://www.w3.org/. See
also namespace and schema.
writable static control block (WSCB)
A
hashing table that contains the addresses of the DLM writable static blocks
used by the ECB.
