Client/Server Structure of the World Wide Web

How does the Web work?

 A Web browser is a software application that runs on the PC to make it work as a Web client  Web servers: computers that store files that are available through the Web  Web pages are stored in files that contain HTML (HyperText Markup Language) instructions, text, images, sound, etc. Copyright 2012 by Janson Industries 5

How does the Web work?

 You need:   Browser (client s/w)  MS IE, Firefox, Safari, Chrome Internet Service Provider (ISP)  Cable, Phone, Starbucks  You request a web resource by:  Clicking on a link  Specifying a resource address Copyright 2012 by Janson Industries 6

Navigating the web

 Use the IE Refresh button to retrieve Web page from server Beware Caching!

 Use the Stop button to abort a transfer (e.g. you accidentally click a hyperlink )  The browser stores the location of each page you visit during a single session in the history list .

Uniform Resource Locator - URL

 Each web page/resource has a unique address called a URL  URL’s can be comprised of: Protocol: // Host / Path /File.name

Example: http: // web.fscj.edu

/ Janson/cgs1060 / syllabus.htm

Host Identification

)  Domain name: subsubdomain.subdomain.tld

(ex. www.fccj.org

Uniform Resource Locator - URL

 Path is the directory/subdirectories where the web page is located on the host  Web page stored in a file with an extension (suffix) of HTML or HTM  File names consist of prefix.suffix (suffix also called extension)  Copyright 2012 by Janson Industries MIME (Multipurpose Internet Mail Extensions) 13

Assignment Data Files

Or if you are having trouble, go directly to this page http://www.cengagebrain.com/cgi wadsworth/course_products_wp.pl?fid=M20b&product_isbn_ issn=9781285418292&token= Copyright 2012 by Janson Industries Click Data Files 46

Specify the location as CGS1060 on the thumb or disk Change the nasty file name to something more meaningful 49 (e.g. MSOffice.zip – must leave

zip

as extension)

The data files are in a zip (i.e. compressed) file that needs to be unzipped First create a new folder in CGS1060 called windata then right click the MSOffice.zip file icon and select Extract All… to start unzipping 51 Copyright 2012 by Janson Industries

Inside that folder are folders for each Unit For instance, the Word files needed in Unit D are in the Unit D folder (The first page of each unit lists the files that will be needed) 55 Copyright 2012 by Janson Industries

Navigating the Web

Directory vs. Search

 Directory can take a while to traverse  What if categories don't really match what you want  For instance, I want to find out info about fabbers  Google directory no help  I searched...

If you don't find what you want....

Search tips

 Putting in multiple words mean all must be present  But not necessarily on the visible portion of the page  Most allow you to use ANDs and ORs to make compound criteria  monkey donkey orangutan monkey

AND

donkey

AND

means orangutan  Minus sign means page can't have the word  monkey

AND

Search tips

 Putting words in double quotes means that exact phrase has to be present  "monkey donkey orangutan"  Instead of searching the entire web specify one website with site  monkey donkey site:youtube.com

Problems with the Web

 Can't believe everything  Anybody can put anything on a page  No "authority" monitors or validates what is put on a page  However, something illegal may get the attention of law enforcement  Poorly designed sites  Traditionally, links on left or at top  Lots of images slows page download 69 Copyright 2012 by Janson Industries

The Web

 More than just pages available  Audio  Music, lectures, books  Can be downloaded or streamed (viewed/listened to live)  Graphics  Pictures  Animation  Video  Virtual reality Copyright 2012 by Janson Industries 70

The Web

 E-Commerce:  Biggest innovation to the Web  Not only buy and sell stuff, services too  Track shipments, look up grades, financial planning, etc  Three types  B2C - efollet  C2C - ebay  B2B – electronic data interchange 71 Copyright 2012 by Janson Industries

The Internet

Netiquette

 General rules for communicating on Internet  CAPS mean your YELLING!

Points to Remember

 The Web is just one portion of the Internet Copyright 2012 by Janson Industries  A browser enables your computer to surf the Web  Browsers also allow you to download files from the Web  Lots of stuff, other than pages, available on the Internet 74
