Motivations

The web document distinction emphasizes the fact that not all content generated by a web template system, web service, and other related systems represents output as a web page.

[edit] Protocol-independent

The e-mail protocols predate the Web protocols, but are not a subset, they constitute distinct Internet services. E-mail documents may be HTML documents, and may be viewed into a e-mail client or through a webmail (or Internet forum) as a web page. A lot of web applications deal with web page bodies and e-mail bodies indistinctly. Web applications deal with web pages, but also with many other formats and protocols.

[edit] Current trends toward XML

From a long-term perspective, the increasing prevalence of XML may eliminate the need for this kind of distinction.

For example:

* Web standards have evolved and become more adaptive toward XML (HTML, for example, can also be expressed as XHTML);
* XML-based OpenDocument specifications (for desktop applications like Open Office) provide an open mechanism for specifying formerly "binary-only" filetypes in plain text (or as binary files of archived text).

Under such trends, the concept of web document becomes more uniform as more file types become expressible as different dialects of XML.

[edit] Dynamic web document

Another extended (derived) concept is dynamic web document, like documents generated from template engines or web services. Dynamic web page is a specific case of dynamic web document. Common Gateway Interface(CGI)is a concept used to create dynamic web document.

WEP stands for "Wired Equivalent Privacy". When WEP encryption is enabled, there are two options: 64-bit and 128-bit. 64-bit is the same as 40-bit WEP. The lower level of WEP encryption uses a 40-bit (10 character) "secret key" (set by the user), and a 24-bit "initialization vector" (not under user control).

Wired Equivalent Privacy (WEP) is a deprecated algorithm to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using radio and are thus more susceptible to eavesdropping than wired networks. When introduced in 1997, WEP was intended to provide confidentiality comparable to that of a traditional wired network.

Beginning in 2001, several serious weaknesses were identified by cryptanalysts with the result that today a WEP connection can be cracked with readily available software within minutes. Within a few months the IEEE created a new 802.11i task force to counteract the problems. By 2003, the Wi-Fi Alliance announced that WEP had been superseded by Wi-Fi Protected Access (WPA), which was a subset of then upcoming 802.11i amendment. Finally in 2004, with the ratification of the full 802.11i standard (a.k.a. WPA2), the IEEE declared that both WEP-40 and WEP-104 "have been deprecated as they fail to meet their security goals".Despite its weaknesses, WEP is still widely in use. WEP is often the first security choice presented to users by router configuration tools even though it provides a level of security that deters only unintentional use, leaving the network vulnerable to deliberate compromise.
