Uniform Resource Locator
<World-Wide Web> (URL, previously "Universal") A standard way of specifying the location of an object, typically a web page, on the Internet. Other types of object are described below. URLs are the form of address used on the World-Wide Web. They are used in HTML documents to specify the target of a hyperlink which is often another HTML document (possibly stored on another computer).
Here are some example URLs:
http://www.w3.org/default.html http://www.acme.co.uk:8080/images/map.gif http://www.foldoc.org/?Uniform+Resource+Locator http://www.w3.org/default.html#Introduction ftp://wuarchive.wustl.edu/mirrors/msdos/graphics/gifkit.zip ftp://spy:secret@ftp.acme.com/pub/topsecret/weapon.tgz mailto:fred@doc.ic.ac.uk news:alt.hypertext telnet://dra.com
The part before the first colon specifies the access scheme or protocol. Commonly implemented schemes include: ftp, http (World-Wide Web), gopher or WAIS. The "file" scheme should only be used to refer to a file on the same host. Other less commonly used schemes include news, telnet or mailto (e-mail).
The part after the colon is interpreted according to the access scheme. In general, two slashes after the colon introduce a hostname (host:port is also valid, or for FTP user:passwd@host or user@host). The port number is usually omitted and defaults to the standard port for the scheme, e.g. port 80 for HTTP.
For an HTTP or FTP URL the next part is a pathname which is usually related to the pathname of a file on the server. The file can contain any type of data but only certain types are interpreted directly by most browsers. These include HTML and images in gif or jpeg format. The file's type is given by a MIME type in the HTTP headers returned by the server, e.g. "text/html", "image/gif", and is usually also indicated by its filename extension. A file whose type is not recognised directly by the browser may be passed to an external "viewer" application, e.g. a sound player.
The last (optional) part of the URL may be a query string preceded by "?" or a "fragment identifier" preceded by "#". The later indicates a particular position within the specified document.
Only alphanumerics, reserved characters (:/?#"<>%+) used for their reserved purposes and "$", "-", "_", ".", "&", "+" are safe and may be transmitted unencoded. Other characters are encoded as a "%" followed by two hexadecimal digits. Space may also be encoded as "+". Standard SGML "&;" character entity encodings (e.g. "é") are also accepted when URLs are embedded in HTML. The terminating semicolon may be omitted if & is followed by a non-letter character.

URL
Uniform Resource Locator. A standard for writing a textual reference to an arbitrary piece of data in the World Wide Web. A URL looks like protocol://host/localinfo where protocol specifies a protocol for fetching the object (such as HTTP or FTP), host specifies the Internet name of the targeted host, and localinfo is a string (often a file name) passed to the protocol handler on the remote host.

URL (Uniform Resource Locator)
the addressing scheme used to link resources on the Web. Like the post office, which must have addresses to deliver mail, Internet users - and their computers - must have addresses in order to send and receive messages. A URL has two parts, separated by by ://. Example:
http://www.whitehouse.gov (Clicking here actually jumps you to the Whitehouse for a cyber-visit.) The portion before the "://" is the web protocol, which could be http://, gopher:// ... The after portion is the name of the computer the person is using - the host.
The name of this host computer may consist of several parts, each separated by a period. The last part tells you what kind of organization owns the computer. For example, gov stands for government, com for commercial organizations, edu for educational institutions, mil for the military, and so forth. Occasionally you see names which end with country codes. The United States designation is us.

Uniform Resource Locator
Uniform Resource Locator (URL) formerly known as Universal Resource Locator, is a technical, Web-related term used in two distinct meanings:
- In popular usage, many technical documents, it is a synonym for Uniform Resource Identifier (URI);
- Strictly, the idea of a uniform syntax for global identifiers of network-retrievable documents was the core idea of the World Wide Web. In the early times, these identifiers were variously called "document names", "Web addresses" and "Uniform Resource Locators". These names were misleading, however, because not all identifiers were locators, and even for those that were, this was not their defining characteristic. Nevertheless, by the time the RFC 1630 formally defined the term "URI" as a generic term best suited to the concept, the term "URL" had gained widespread popularity, which has continued to this day.
