.org

The domain name org is a generic top-level domain (gTLD) of the Domain Name System (DNS) used in the Internet. The name is truncated from organization. It was one of the original domains established in 1985, and has been operated by the Public Interest Registry since 2003. The domain was originally intended for non-profit entities, but this restriction was not enforced and has been removed. The domain is commonly used by schools, open-source projects, and communities, as well as by for-profit entities. The number of registered domains in org has increased from fewer than one million in the 1990s, to ten million as of June, 2012.

History

The domain org was one of the original top-level domains, with com, us, edu, gov, mil and net, established in January 1985. It was originally intended for non-profit organizations or organizations of a non-commercial character that did not meet the requirements for other gTLDs. The MITRE Corporation was the first group to register an org domain with mitre.org in July 1985. The TLD has been operated since January 1, 2003 by Public Interest Registry, who assumed the task from VeriSign Global Registry Services, a division of Verisign.

List of Power Rangers Wild Force characters

Power Rangers Wild Force is the 2002 Power Rangers season that tells the story of the Wild Force Power Rangers and their fight against the polluting Orgs.

Wild Force Power Rangers

The Wild Force Rangers are granted mystical powers and charged to protect the Earth from pollution-created creatures called Orgs. More specifically, they defend the fictional city of Turtle Cove, and are stationed aboard a flying island called the Animarium. Their mentor is Princess Shayla, and her mentor is Animus (who is an ancient Megazord). The Rangers represent the Ancient Animarium Warriors who also fought to destroy the Orgs and save the Earth.

The Rangers morph using devices known as Growl Phones (which have three operating modes: normal, human-form, and Power Animal Mode that resembles an animal). Each Ranger is also armed with a Crystal Saber (into which an Animal Crystal is inserted to call a Wild Zord). In addition to piloting their Zords (known as Wild Zords), the Rangers pilot other vehicles, known as the Soul Bird and the Savage Cycles. When the Rangers put their weapons together they create the Jungle Sword, which can be used by the Red Ranger to defeat certain enemies.

5-1-1

5-1-1, initially designated for road weather information, is a transportation and traffic information telephone hotline in some regions of the United States and Canada. Travelers can dial the three-digit telephone number 5-1-1 on traditional landline telephones and most mobile phones. It is an N11 code of the North American Numbering Plan that are used for special services. The number code has also extended to be the default name of many state/provincial transportation department road conditions websites, such as Wisconsin's site.

As of March 2001, at least 300 telephone numbers existed for travel information systems in the United States. To overcome the confusion caused by this array of numbers, the United States Department of Transportation (USDOT) petitioned the Federal Communications Commission (FCC) for a national assignment of a single three-digit N11 dialing code. On July 21, 2000, the FCC assigned 511 as a nationwide telephone number for ITS traveler information, along with 2-1-1 for social services. Its use is being promoted by the USDOT's Intelligent Transport Systems initiative.

Maximum transmission unit

In computer networking, the maximum transmission unit (MTU) of a communications protocol of a layer is the size (in bytes or octets) of the largest protocol data unit that the layer can pass onwards. MTU parameters usually appear in association with a communications interface (NIC, serial port, etc.). Standards (Ethernet, for example) can fix the size of an MTU; or systems (such as point-to-point serial links) may decide MTU at connect time.

A larger MTU brings greater efficiency because each network packet carries more user data while protocol overheads, such as headers or underlying per-packet delays, remain fixed; the resulting higher efficiency means an improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data. In some systems, per-packet-processing can be a critical performance limitation.

However, this gain is not without a downside. Large packets occupy a slow link for more time than a smaller packet, causing greater delays to subsequent packets, and increasing lag and minimum latency. For example, a 1500-byte packet, the largest allowed by Ethernet at the network layer (and hence over most of the Internet), ties up a 14.4k modem for about one second.

XMPP

Extensible Messaging and Presence Protocol (XMPP) is a communications protocol for message-oriented middleware based on XML (Extensible Markup Language). It enables the near-real-time exchange of structured yet extensible data between any two or more network entities. Originally named Jabber, the protocol was developed by the Jabber open-source community in 1999 for near real-time instant messaging (IM), presence information, and contact list maintenance. Designed to be extensible, the protocol has also been used for publish-subscribe systems, signalling for VoIP, video, file transfer, gaming, Internet of Things (IoT) applications such as the smart grid, and social networking services.

Unlike most instant messaging protocols, XMPP is defined in an open standard and uses an open systems approach of development and application, by which anyone may implement an XMPP service and interoperate with other organizations' implementations. Because XMPP is an open protocol, implementations can be developed using any software license; although many server, client, and library implementations are distributed as free and open-source software, numerous freeware and commercial software implementations also exist.
