FTP is like using windows explorer to drag files around from one part of your computer to another

FTP is similar to using Windows Explorer to move files around.
Basically you need to take the ".htm" files , and images, you have made, and transfer them from your computer to the computer acting as the server for the web site. Its called a server because when the viewer calls up the page, the host "serves it" so it can be viewed.

One of the most popular reason why you cannot see something on a web page is because the file you are looking for, has not been properly FTP'd to the server.

HTML Structure

Creating a web page 

Prof. Richardson will briefly show in class the basics of using a representational editor, like Netscape Composer, to create a page that contains

  • text
  • elements of character formatting
  • images
  • tables
  • linking pages
all of which is covered in the text page 107 - 124

Chapter 4
The following terms and phrases in Chpt 4 may be recognizable to students who have gone through the process of setting up their computer to send and receive e-mail, but perhaps you entered these terms into profile boxes without knowing what they mean or what role they play.

You should read Chpt 4 on your own, particular 
pages 142-143, 148, 150, 152-153, 160-165, 168, (1st ed.)

  • E-mail clients and e-mail servers: how they interact
  • SMTP - Simple Mail Transfer Protocol is the protocol used to send mail over the Internet
  • POP - a protocol used when a client downloads e-mail messages from a server
  • IMAP - POP has some limitations that may be replaced by IMAP
  • Telnet - is a protocol used to pass commands and replies between the client and the UNIX computer. Sometimes a UNIX computer cannot be FTP'ed, but you can always telnet in

Chpt 6, page 130 Creating Stores on the Web
. In order to make good web pages, you not only need to create the words, but also shape and move images around. Some images are ones you create, other images are scans of photos and diagrams.

Having access to, and being able to competently use a image package, such as Photoshop, is critical to putting together an attractive site.

FYI, many web page authoring software packages also contain image editing software on the CD, eg.

HoTMeTaL 6.0 also contains Photoimpact

Basics of 
Web Graphics

Chpt 6
Chpt 6, page 139-140 Creating Stores on the Web

There are three basic file formats that you will most encounter 

  • .jpg
  • .gif
  • animated gifs
JPEG is best used for large pictures which may be slow to load so you use the JPEG format which will compress the pic more and make it a smaller file size 

GIF is best when you have people accessing the image who have fast computers and a good connection. GIF formats take up more space than JPEG and as a result there is a better rendering of the image because it uses more pixels. 

Animated GIFS are actually layers GIFS which are repeatedly shown so it appears as if the image moves. Some people use small animated GIFS to draw attention to a feature on a page, like

Prof. Richardson teaches a courses titled "Advanced HTML" at another institution. In one section of this course (which is also online) there is a lot of material about images and audio to web pages. Rather than cramming that content into this MGTC50 page, you are encouraged to click on the screen captures below and go to that other site.

In addition, you are encouraged to read Chpt 4 in the i-NET+ Guide (2nd ed.) (Chpt 5 1st ed.) since it has some very good explanations, including instructions for putting images and audio on your pages.
 
. In considering the addition of audio and visual content to a working e-commerce site - which you are understanding to build for MGTC50 - it is important for you to know the limitations of the average person browsing your site.
For example, if you have an intro page with a kewl "flash" image, and many of your visitors do not have a flash plug-in, then you have to provide an alternate entry page.

Knowing about the latest image and sound applications, and marrying this with an understanding of the browsers used by typical visitors to your site, will allow you to create a total "experience" that loads quickly, and is interesting and informative.

BCS 500 page on sound

WTGR

.
Understand that adding sound to your web site is a relatively new feature of sites since most people accessing the web have had speakers on their PCs less than 3 years. Furthermore, the use of sound is a bit complicated because Netscape and Microsoft have adopted different ways of playing sound that differ from each other.

There are two basic types of sound files
1. recorded
2. synthesized

All audio data can be categorized into three characteristics
 
1. sampling rate in samples per second "The sampling rate of a sound is the number of times that a sound is divided up, measured, and recorded. The smaller and more numerous the samples per second, the closer the digital sound comes to recreating the natural experience of sound."
2. number of bits used to record each sample "The bit rate determines how "fine" or "granular" the sound is being recorded. Typically, most sound formats are recorded at eaither 8 bits or 16 bits". Remember, more bits means more memory so a high sampling will require more storage space.
3. number of channels of sound "A single channel of sound is used for mono sound, and two channels is used for stereo".

Netscape
Internet Explorer
"Ever since the release of Netscape Navigator 3.0, sound is played through a built-in plug-in called Live-Audio. Netscape's Live-Audio can play the following sound file formats" page 450 Microsoft also did a built-in audio player so anybody using I.E. 3.0 or higher can also hear sound recordings ending in the following formats. page 450

. WARNING - finding, playing and listening to MIDI files online can be addictive - there are thousands of sites catering to every taste which can cause you to get lost for hours - do not do go surfing for midis the nite before a big test. :-)

MIDI is the acronym for Musical Instrument Digital Interface
MIDI was introduced in 1983.

For more detailed intro to MIDIs, read the explanation page on midi.com's site at
 www.midi.com/questions/introtomidi.asp

Midi files are some of the first kind of files people add to their page when they are first starting to experiment with adding sounds.
They are easy to find, and do not require any fancy plug ins since most basic computers come with the necessary simple players to handle playing the file.

You can put .midi files on a page with the url, like this
 http://www.witiger.com/music/BobMarley~Jammin.midi
 
 
or you can link them to an image, like this http://www.witiger.com/music/CanadaAnthem.midi

Comparing .MIDI files to other formats, check this
getdown - Kool and the Gang

Comparing .MIDI files to other formats
check this
miamivicetheme.midi
takes only 13 kb of space and loads almost instantly
 www.witiger.com/music/miamivice.midi
miamivicetheme.wav
here is the same song again, only in the .wav version

takes 646kb of space and takes a while to load, which is bad cause the person browsing the page may be impatient and move on

. Why did we spend a particular amount of time in MGTC50 talking about sound on web pages --- because from 1997-2001 - which is the early period within which most people started accessing the web - most of the content has been in text and image form - it is expected that in 2003 and beyond, that more content will be in audible formats to allow delivery to cell phones, and other instruments - therefore the reason you should know about, and be aware of sound on the WWWeb.

Domain Names

Chpt 6
Chpt 6, page 125 Creating Stores on the Web

A short one page on some of the issues.
Key points to remember

  • the base cost of acquiring a domain name from a reputable registrar is $100 which includes first and second year
  • when the text was written there was only one registrar, Network Solutions, now there are many registrars all competing
Most of the relevant info is at
 http://www.witiger.com/ecommerce/domainnames~register.htm
as seen in the screen capture below

Chapter 7

In the i-Net+ Guide 2nd Edition, Domain Names are discussed for a few pages in Chpt 7, beginning on page 380

"Domain names are an alternate way of addressing a host on the Internet [instead of using numbers], but all domain names eventually must be mapped to a host's IP address before contact with the host can take place. Think of a domain name as an alias; the real name of the host computer is the IP address".
 

. Try this, click on both links, they both go to the same web site. One link shows the domain name as a word, the other as an IP address.

 http://66.39.90.154/
and
 http://www.larkhill.com/

sometimes people launch a website without having the domain name configured completely, so they just go by the IP address while it is in draft form, see example below
 http://209.68.31.5/

Domain names can be further divided into subdomains, such as support.microsoft.com - when we do this, it is called a subcategory and known by the term canonical name or CNAME

Chapter 7

In the i-Net+ Guide 2nd Edition, page 382 it talks about
"How to Create and Update a Domain Name"

Chapter 5
. Business Models is a topic that is discussed in detail in MGTD06 
http://www.witiger.com/ecommerce/outlineMGTD06b.htm - since that course is about the marketing and strategy of e-business whereas MGTC50 is primarily about the details of building a working site. However we cannot begin MGTC50 without a basic intro to business models - even if it will be discussed in detail later in MGTD06. We need some basic understanding of business models so you have a framework within which to build your "solution".

WTGR

Narrow Interest Aggregation - interact with customers on an individual basis
Low Cost of Entry - barriers to entry are significant for brick and mortar stores
Leveraging technology - mostly related to cutting costs

Business Models

  • Traditional Online Store ! - not really such a creature
  • Auction House - have been some massive problems with these in 2000
  • Broker/Virtual Store - often dealing with specific segments
  • Associate Store - an extension of an existing mail order store
  • Electronic Distribution Store - for digital products and services
  • In-Stock Advantage - usually for specific market segments
  • Content Attraction - making something up that did not exist before
  • online Associate / Affiiate Store - same as Web Rings
  • Price Buster - Discounters
  • Shopping Clubs
  • Sales-Lead Generator - re-sellers of demographic info and emails and addresses
As we can see form the list above, the variety of e-business models is as extensive as the variety of brick and mortar stores - that is to say by 2001, there are many many ways of making something, and selling it to other people.
