Technology Infrastructure:
The Internet and the World Wide Web
![Page 5: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/5.jpg)
Types of Networks
• A local area network (LAN) is a network of computers close together.
• A wide area network (WAN) is a network of computers connected over a great distance.
![Page 6: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/6.jpg)
Switched Networks
• The Internet uses packet switching• Files are broken down into small pieces
(called packets) that are labeled with their origin, sequence, and destination addresses.
![Page 7: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/7.jpg)
Routing Packets• The computers that decide how best to
forward each packet in a packet-switched network are called ‘routers’.
• The programs on these routers use ‘routing algorithms’ to determine the best path to send each packet.
• These routers and the telecommunication lines connecting them are referred to as ‘the Internet backbone’.
![Page 8: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/8.jpg)
Internet Protocols (IP)
• A protocol is a collection of rules for formatting, ordering, and error-checking data sent across a network.
• ARPANET is the earliest packet-switched network.
• The open architecture of this experimental network used Network Control Protocol (NCP) which later became the core of the Internet.
![Page 9: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/9.jpg)
TCP/IP
• The Transmission Control Protocol (TCP) and the Internet Protocol (IP) are the two protocols that support the Internet operation (commonly referred to as TCP/IP).
• The TCP controls the disassembly of a message into packets before it is transmitted over the Internet and the reassembly of those packets when they reach their destination.
• The IP specifies the addressing details for each packet being transmitted.
![Page 10: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/10.jpg)
Domain Names
• To make the numbering system easier to use, an alternative addressing method that uses words was created.
• An address, such as www.course.com, is called a domain name.
![Page 11: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/11.jpg)
URL (Uniform Resource Locator)
• Internet address• Three parts
• Protocol (how file will be sent)• Domains (computer path to file)• File pathname (folders and filename)
![Page 12: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/12.jpg)

Hypertext Markup Language
• HTML is a simplified subset of SGML (Standard Generalized Markup Language) that includes tags defining the format and style of text elements in a document.
• HTML now includes tags for tables, frames, and other features that help Web designers create more complex page layouts.
![Page 14: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/14.jpg)
HTML Tags• Tags are codes that are used to define
where an HTML element starts and (if necessary) where it ends.
• In an HTML document, each tag is enclosed in brackets (<>).
• A two-sided tag set has an opening tag and a closing tag.
![Page 15: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/15.jpg)
Nested Information• Tags work in pairs• Nest the pairs

Scripting Language and Style Sheet Capabilities
• Web designers can use the OBJECT tag to embed scripting language codes in HTML pages (this is also called client-side scripting).
• Scripts can execute programs on computers that display those pages.
• Cascading Style Sheets (CSS) let designers define formatting styles that can be reapplied to multiple Web pages.

Electronic Commerce
• Electronic Funds Transfers (EFTs) have been used by banks for many years.
• Electronic Data Interchange (EDI) occurs when one business transmits computer-readable data in a standard format to another business.
![Page 20: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/20.jpg)

Electronic Data Interchange (EDI)
The primary goals of EDI are: Cut the transaction costSpeed up the ordering process
There are two important considerations:Establishing the physical linkTransferring data in a format compatible to all users
![Page 22: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/22.jpg)
Advantages of E-Commerce
• Cut data handling cost• Easier to search for data and compare
offerings• Electronic commerce increases sale
opportunities for the seller. Web advertising reaches a large amount of potential customers throughout the world.
![Page 23: What is Electronic Commerce?. Learning Objectives Internet, Intranet, Extranet Technology Infrastructure –How packet-switched networks are combined to](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e0c5503460f94af4c8b/html5/thumbnails/23.jpg)
Disadvantages of E-Commerce
• Some business processes are difficult to be implemented through electronic commerce.
• Computers are needed - Computers are not as portable as catalog
• There are concerns about security provisions on the internet
• Businesses face cultural and legal obstacles to conducting electronic commerce.
