  2. Web Site. • A location on the World Wide Web that contains a collection of related documents and a common top-level address.

  3. Index Page. (Home Page.) • A default page that automatically displays when the top level of a Web site is accessed.

  4. URL (Uniform Resource Locator). • The unique and complete address that specifies precisely the location of a document or resource on the World Wide Web.

  5. 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/

  6. Resource Name. • The portion of a URL specifying file name and extension. Examples are index.html or style.css.

  7. 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.

  8. Boolean Operators. • The operators AND, OR, and NOT, often used with keywords to specify search parameters.

  9. Search Engine. • A program to locate information in a database. A service providing a searchable database of Web documents.

  10. Wildcard Character. • A symbol, such as an asterisk, used to represent a string of characters, and often supported by search engines.

  11. 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.

  12. E-commerce. • Short for electronic commerce, it is the business of buying and selling products online.

  13. Encryption. • The process, using a cipher key, of converting information so that it cannot be understood or changed back into its original form without the key.

  14. Secure Mode. • In a Web browser, the mode of operation in which all communications are encrypted.

  15. World Wide Web Consortium (W3C). • An international consortium of experts that specifies standards for www languages and development.

  16. Declarative Language. • A computer language that can be used to identify the components of a text and codify their presentation. (Synonymous with markup language.)

  17. HTML (Hypertext Markup Language). • A standardized, plain text document format used to display Web pages. Markup refers to the code tags, such as <html> or <table>, and the method of marking the code (brackets).

  18. HTML Tag. • A markup inserted into an HTML document to provide information about a unit of content. All HTML tags are enclosed in brackets (ie. <table>). Some tags require closing tags (ie. </table>).

  19. HTML Elements. • In HTML, elements are markup declarations to display or format parts of Web pages. Examples are <p> for paragraph or <b> for bold.

  20. Attribute. • In the context of HTML, additional required or optional information enabling specification of characteristics of elements and related values (ie. <table width =”80%">).

  21. Value. • In the HTML context, a value specifies information about an attribute, is often required, and is typically preceded by an equals sign and enclosed in quotation marks (ie. <font color=“red”>).

  22. Standard Generalized Markup Language (SGML). • A document type definition (DTD) standard for how to specify a markup language or tag set.

  23. Extensible Markup Language (XML). • A simplified, easy-to-use version of SGML similar to HTML that allows definition of customized tags.

  24. 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.

  25. Web Server. • A computer that uses software to transmit Web pages and associated files over the Internet.
