Index Page. (Home Page.) • A default page that automatically displays when the top level of a Web site is accessed.
URL (Uniform Resource Locator). • The unique and complete address that specifies precisely the location of a document or resource on the World Wide Web.
Path. • The portion of a URL that specifies the location of a document on the Internet, including the domain name and site folders. An example is jqjacobs.net/edu/cis105/
Resource Name. • The portion of a URL specifying file name and extension. Examples are index.html or style.css.
Hypertext Transfer Protocol (HTTP). • The rules specifying the format of URLs and the procedures clients and servers utilize to communicate. Also, http:// is the identifier at the beginning of a URL.
Boolean Operators. • The operators AND, OR, and NOT, often used with keywords to specify search parameters.
Search Engine. • A program to locate information in a database. A service providing a searchable database of Web documents.
Wildcard Character. • A symbol, such as an asterisk, used to represent a string of characters, and often supported by search engines.
Proximity Operator. • A symbol or keyword, such as NEAR, used in searches to retrieve records only if two specified words occur close to each other.

World Wide Web Consortium (W3C). • An international consortium of experts that specifies standards for www languages and development.
Declarative Language. • A computer language that can be used to identify the components of a text and codify their presentation. (Synonymous with markup language.)

Standard Generalized Markup Language (SGML). • A document type definition (DTD) standard for how to specify a markup language or tag set.
Extensible Markup Language (XML). • A simplified, easy-to-use version of SGML similar to HTML that allows definition of customized tags.
Cascading Style Sheets (CSS). • A markup language providing specific presentation information for single html tags, for all specified tags in a document, or, as a linked document, for many documents.
Web Server. • A computer that uses software to transmit Web pages and associated files over the Internet.
