Gateway has several meanings. It may often share meanings with the term gate.

[edit] Computer Terminology

  • Gateway is a common term in telecommunications; see gateway (telecommunications). A gateway, in the aforementioned sense, is very popular, as it is a computer or a network that allows or controls access to another computer or network.
  • 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.
  • Gateway is also a technical term for the software interface between a web-based shopping cart (or order form) and a merchant account (See also electronic commerce and payment gateway).
  • Gateway also refers to a link in computer programs. Most often attributed to viruses, a gateway acts as a portal between two programs allowing them to share information and bypass certain protocols on a host computer. Although seemingly harmless, a gateway can have tremendous negative effects on personal computers if not used properly.
  • Gateway, in networking technology, is a node that serves as an entrance to another network, and vice-versa. This is, in fact, an earlier name for Routers and both actually focus on the same concept - that is, hardware or software that routes (and filters) data coming through it. This retronym, however, now describes the same hardware or software technology that are mostly implemented in corporate enterprises that not only does routing and filtering of data, but also can include added routing, proxy functionality, as well as being advanced as to have Antivirus software scanning and filtering capabilities.
