Web Architecture 8

Website Vs WebPage Vs Web Domain Vs Web Hosting Vs Web Browser Vs URL ? WEBSITE : A system of Internet servers that support specially formatted documents. The documents are formatted in a script called HTML (HyperText Markup Language) that supports links to other documents, as well as graphics, audio, and video files. 9

WEB PAGE a document on the World Wide Web. Every Web page is identified by a unique URL (Uniform Resource Locator). 10

URL Abbreviation of Uniform Resource Locator, the global address of documents and other resources on the World Wide Web. The first part of the address indicates what protocol to use, and the second part specifies the IP address or the domain name where the resource is located. For example, the two URLs below point to two different files at the domain binus.ac.id. The first specifies an executable file that should be fetched using the FTP protocol; the second specifies a Web page that should be fetched using the HTTP protocol: ftp:// 11

Four components of a URL 1.The web protocol 2.The name of the web server 3.The directory on that server 4.The file within that directory 12

HTTP Short for HyperText Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page. 13

Web browser Internet Explorer, Netscape, Opera, Google Chrome maupun Mozilla Firefox 14

Elemen Web Browser The five basic elements of a web browser are: Menu bar Toolbar URL bar Workspace Status bar 15
