Week 3
Trang 2• Defining the Internet
• Internet tools to access information
• The world wide web
• Intranets versus extranets
• Web site hosting
• Internet Retailing
• Internet Marketing Mix
Trang 3What is the Internet
• Started in 1960s as the ARPAnet research and
defense network in the USA
• Infrastructure: the hardware, software, databases and telecommunications
• Services: Software-based services such as search engines, digital money and security systems
• Products and services: the web sites of individual companies and marketplaces
Trang 4The Internet
• As compared with other alternative technologies the
Internet offers:
– international connectivity and access to international markets,
– a strong North American market, which in many senses could be viewed as the domestic market for most Internet retailers,
– full multimedia display facilities, which allow retailers to display and demonstrate their products, possibly with the use of audio and video (in some cases, as in the sale of music, for example, such facilities allow the customer to sample the product),
– more sophisticated electronic ordering and payment facilities,
– much larger installed base of workstations, thus giving access to customers, in both the consumer and business sectors of the
marketplace
Trang 5The Internet refers to the physical network that links computers across the globe It
consists of the infrastructure of network
servers and communication links between them that are used to hold and transport the vast amount of information on the Internet The Internet enables transfer of messages and transactions between connected computers
worldwide.
Trang 6The passing of data packets around the Internet occurs via the TCP/IP protocol, or transfer Control Protocol/Internet Protocol For a PC to be able to receive web pages or for a server to host web pages it must be configured to support this protocol
Trang 7Application of Different tools
Internet tool Summary
Electronic mail or e-mail Sending messages or documents, such as news about a new product or sales
promotion between individuals A primitive form of push channel
Internet relay chat (IRC) This is a synchronous communications communications tool that allows a text-based
chat between different users who logged on at the same time Of limited use for marketing purpose
Usenet newsgroups An electronic bulletin board used to discuss a particular topic such as a sport, hobby
or business area Traditionally accessed by special news reader software, these can now be accessed via a web browser from Deja News (www.dejanews.com)
FTP file transfer The File Transfer Protocol is used as a standard for moving files across the Internet
Used to download files and update HTML (Hypertext Markup Language) files on web pages
Gophers, Archie and WAIS These tools were important before the advent of the World Wide Web for storing and
searching documents on the Internet They have been superseded by the web
Telnet This allows remote access to computer systems For example a retailer could check to
see whether an item was in stock in a warehouse using telnet
Push channel Information is broadcast over the Internet or an intranet and received using a web
browser or special program for which a subscription to this channel has been set up World Wide Web www is widely used for publishing information and running business applications
over the Internet
Trang 8Web Browsers and servers
• Enable web addresses to be entered, to set up communications links with sites and to download HTML pages.
• Display web pages and interactive forms,and to run programs such as plug-ins and Java
• Enable navigation between sites by using forward and
backward options and hyperlinks
• Record on the hard disk a copy of sites visited and the pages downloaded (caching), to enable quicker downloading and
referencing in future.
• Allow useful sites to be bookmarked for later use
• Enable information to be saved to disk or printed for a later use
Trang 9The Benefits of Web Browsers
• Easy to use since navigation between documents
is enabled by clicking on hyperlinks or images
• They can provide a graphical environment
supporting multimedia, which is popular with
users and gives a visual medium for advertising
• The standardization of tools means there is a large and fast-growing target market
Trang 10How Are Web Pages Displayed
• User requests web page by clicking on a hyperlink or
typing in URL (Universal Resource Locator) into web
browser.
• Request is sent across Internet from web browser to web server using http (hypertext transfer protocol)
• Information is returned using http from web server to web browser
• Information is displayed as the different elements of a web page
Trang 11Main Elements of a Web Page
• Text information (HTML and XML)
• Static graphical images (GIF and JPEG files)
• Animated graphical images (GIFs and plug-ins)
• Interactive form elements (CGI – Common
Gateway Interface and script elements)
• Plug-in components

Trang 13Connecting to the Internet as a User
• Hardware –
– Computer to run the web browser and software required – Modem, gateway server
– Digital or analogue connection
• Software
– Web browser (Netscape, explorer)
– Connectivity software - TCP/IP standard
• A service provider
Trang 14Hosting a Web Site
• Register domain name
• Find ISP to connect to the Internet or host web server
• Find an appropriate server computer to enable the following standards:
– http:// serving web pages
– ftp:// remote file access
– SMTP Internet e-mail
• Develop graphic and HTML content
• Upload to web server using FTP to transfer files
Trang 15Development stages
• Maglitta (1994) identifies the following initial development stages associated with opening for business on the Internet:
– set the information-sharing policy,
– restructure database,
– develop applications,
– integrate external and internal databases,
– test links with customers,
– negotiate the role of sales,
– develop a marketing strategy, and
– deploy client software
Trang 16Advantages of Internet Retailing
• Small businesses can extend their reach
• It eliminates prohibitive costs of entry to many industries
• Hardware and software advances permit improved interfaces and
functionality
• Online information is current
• Interaction with customer representatives and immediate ordering are possible
• It eliminates costs associated with the store, salespeople and possibly some warehousing costs
• As compared with conventional catalogues there are no printing and mailing costs, and the information can be rapidly changed and updated
• Much more extensive advertising coverage can be achieved for a
relatively small outlay
Trang 17Internet Marketing Mix
• Promotion - includes advertising and creating product
awareness Information must be presented in a way that will hold the users' interests
• One-to-one contact - unlike a real store, the Net does not offer
marketers opportunities of synchronous one-to-one contact with customers The Net does, however, allow for asynchronous
contact via e-mail, and this can be used to develop a relationship with a customer
• Closing - involves setting the price and closing the deal While
this can be achieved through a collection of e-mail messages,
Net buying is more like ordering from a catalog On the other hand, there is an electronic record of the sale and the deal struck
Trang 18Internet Marketing Mix Con’t
• Transaction - payment for goods is typically made
in cash, or by credit card Digital forms of
currency are also being developed by companies like DigiCash, CyberCash and NetCash
• Fulfillment - involves the delivery of goods
Delivery online is restricted to digital products
such as electronic books and software Fulfillment includes not only shipping, but also effective
electronic order processing
