Gateway was an American jazz trio formed in 1975. The members were John Abercrombie, guitar, Dave Holland, bass, and Jack DeJohnette, drums. The group has also joined Collin Walcott on his debut album Cloud Dance (ECM 1062) recorded in 1975. The trio reunited temporarily for a performance in 2012 to mark DeJohnette's 70th birthday.

Gateway (Frederik Pohl's Gateway, 1992) and Gateway II (Gateway II: Homeworld, 1993), are interactive fiction games released by Legend Entertainment, and written by Glen Dahlgren and Mike Verdu. They are based on Frederik Pohl's Heechee universe.

Βoth games have virtually identical interfaces that hybridize traditional parsers with illustration and mouse-based aids. The games (especially the second) have a number of timed events, but the possibility of player death outside them is quite rare. Unwinnable states are possible, but difficult to achieve.

Gateway is a fictional superhero appearing in American comic books published by Marvel Comics. The character has been depicted as an Australian mutant with the ability to teleport objects and people from one location to another. He is considered an unofficial member of the X-Men.

Gateway is a 1977 science fiction novel by American writer Frederik Pohl. It is the opening novel in the Heechee saga. Several sequels followed, and the novel was adapted into a computer game in 1992.

Gateway won the 1978 Hugo Award for Best Novel, the 1978 Locus Award for Best Novel, the 1977 Nebula Award for Best Novel, and the 1978 John W. Campbell Memorial Award for Best Science Fiction Novel.

Gateway is the third full-length album by stoner metal band Bongzilla. It was released in September 2002 by Relapse Records. The title of the album is a reference to the term " gateway drug", used to describe an apparently more-benign drug that can lead to the use of more dangerous drugs.

Gateway is a phrase used by webmasters and search engine optimizers to describe a webpage designed to attract visitors and search engines to a particular website. A typical gateway page is small, simple and highly optimized. Its primary goal is to attract visitors searching for relevant key words or phrases, and provide hyperlinks to pages within the website.

In telecommunications, the term gateway refers to a piece of networking hardware that has the following meaning:

• In a communications network, a network node equipped for interfacing with another network that uses different protocols.
  • A gateway may contain devices such as protocol translators, impedance matching devices, rate converters, fault isolators, or signal translators as necessary to provide system interoperability. It also requires the establishment of mutually acceptable administrative procedures between both networks.
  • A protocol translation/mapping gateway interconnects networks with different network protocol technologies by performing the required protocol conversions.
• Loosely, a computer or computer program configured to perform the tasks of a gateway. For a specific case, see default gateway.

Gateways, also called protocol converters, can operate at any network layer. The activities of a gateway are more complex than that of the router or switch as it communicates using more than one protocol.

Both the computers of Internet users and the computers that serve pages to users are host nodes, while the nodes that connect the networks in between are gateways. For example, the computers that control traffic between company networks or the computers used by internet service providers (ISPs) to connect users to the internet are gateway nodes.

In the network for an enterprise, a computer server acting as a gateway node is often also acting as a proxy server and a firewall server. A gateway is often associated with both a router, which knows where to direct a given packet of data that arrives at the gateway, and a switch, which furnishes the actual path in and out of the gateway for a given packet.

On an IP network, clients should automatically send IP packets with a destination outside a given subnet mask to a network gateway. A subnet mask defines the IP range of a private network. For example, if a private network has a base IP address of 192.168.0.0 and has a subnet mask of 255.255.255.0, then any data going to an IP address outside of 192.168.0.X will be sent to that network's gateway. While forwarding an IP packet to another network, the gateway might or might not perform Network Address Translation.

A gateway is an essential feature of most routers, although other devices (such as any PC or server) can function as a gateway.

Most computer operating systems use the terms described above. Microsoft Windows, however, describes this standard networking feature as Internet Connection Sharing, which acts as a gateway, offering a connection between the Internet and an internal network. Such a system might also act as a DHCP server. Dynamic Host Configuration Protocol (DHCP) is a protocol used by networked devices (clients) to obtain various parameters necessary for the clients to operate in an Internet Protocol (IP) network. By using this protocol, system administration workload greatly decreases, and devices can be added to the network with minimal or no manual configurations.

Gateway is the name of a small industrial and residential neighborhood in Northeast Washington, D.C. It is bounded by New York Avenue NE to the south and southeast, Bladensburg Road to the west, and South Dakota Avenue to the northeast. Gateway is across New York Avenue from the U.S. National Arboretum.

The neighborhood takes its name from the period when the Washington Branch of the Baltimore and Ohio Railroad ran in place of present-day New York Avenue. The eastern edge of the District of Columbia was occupied by the military jurisdiction of Fort Lincoln, but Gateway (immediately southwest of Fort Lincoln) was the first civilian area of the District through which trains would pass.

Gateway is home to the printing press facility for the Washington Times newspaper.

A gateway is a link between two computer programs or systems such as Internet Forums. A gateway acts as a portal between two programs allowing them to share information by communicating between protocols on a computer or between dissimilar computers.

Some examples of common gateways:

• E-mail <-> News server
• News server <-> Internet forum
• RSS aggregators <-> News server
• XMPP <-> ICQ
