Indexer

The part of the search engine that processes and places spidered, or crawled, web documents into a database. The indexer typically processes a document by removing all tags, storing links in a queue, removing filter words, looking for stop words, and storing the document in a searchable database.

Information Architecture

Information Architecture - The study of the organisation and structure of effective web systems. In particular, the relationships between internal page elements, as well as the relationship between individual pages.

Intellectual Property

Intellectual Property, or IP, is the group of legal rights to things people create or invent. Intellectual property rights typically include patent, copyright, trademark and trade secret rights.

Internet Explorer

Microsoft Internet Explorer is the leading Web browser for the Microsoft Windows Operating System. Internet Explorer, also known as MSIE or IE, was initially based on a version of the Mosaic browser. Internet Explorer is included for free with Microsoft Windows. In the past, Microsoft has been criticised for anti-competitive behaviour for requiring Internet Explorer to be packaged with all new computers using Microsoft Windows. Internet Explorer has a reputation as the least secure of the major browsers. Internet Explorer 6.0 was released in 2001. In the past, some versions of Internet Explorer for Macintosh OS were released, though Internet Explorer for Mac is now discontinued and is only available for the Microsoft Windows platform.

Internet Service Provider (ISP)

Abbreviation for Internet service provider. An ISP is a company that provides access to the Internet.

Invisible web

Web sites or pages that search engine spiders cannot or will not crawl because the content is locked up in a database.

IP Address

The unique numeric identifier of every computer connected to the Internet. Each IP address consists of a four number pattern separated by periods (XX.XX.XX.XX). Each number must be between 0 - 255. IP adresses work with DNS servers to direct and route requests through the Web. Although home users have IP addresses, the process is normally transparently handled by the ISP.

IP delivery

A type of cloaking technique where customized content is delivered to a site visitor based on the visitor's IP address. Because search engines have unique IP addresses, content delivered to the search engines is not the same content delivered to site visitors.

IP spoofing

The act of sending messages to a computer using an IP address from a trusted source to gain unauthorized access to that computer. IP spoofing is illegal in many countries.
