for E-Commerce
UNIT-II
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
• Electronic commerce is an emerging concept that describes the process of
buying and selling or exchanging of products, services and information
via, Tele- communication and computer networks including the internet.
• Electronic commerce needs a network infrastructure to transport the
content- data, audio, visual, text, animation and so on. This network
infrastructure is provided by what is known as the I-way or information
super highway.
ELECTRONIC COMMERCE
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
COURSE OUTLINE
• Introduction to information superhighway,
• Components of the I-way,
• Internet as network infrastructure, TCP/IP Protocol suite,
Intranet, Extranet etc
• Software agents (static and dynamic),
• Broadband technologies (xDSL, Wi-Fi, WAN).
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
INTRODUCTION TO I-WAY
• The I-way has emerged as the basic network infrastructure for all types of E-
commerce activities due to its capability to provide integrated voice ,data and
video services . I-way has changed the way business advertises, market or sell
their products and services. This paper highlights the network infrastructure
in E-Commerce.
• A physical network, an infrastructure of modern high-speed links links
everyone at home or office to everything else in practicality it is identical to
internet provided -connections are broadband -they are continuously running
as internet develops into I-way, changes will take place in infrastructure not in
internet

INTERNET AND INTRANET BASED E-
COMMERCE- ISSUES,
Internet
• This is the world-wide network of computers accessible to anyone who
knows their Internet Protocol (IP) address - the IP address is a unique set of
numbers (such as 209.33.27.100) that defines the computer's location.
Intranet
• This is a network that is not available to the world outside of the Intranet. If
the Intranet network is connected to the Internet, the Intranet will reside
behind a firewall and, if it allows access from the Internet, will be an
Extranet. The firewall helps to control access between the Intranet and
Internet to permit access to the Intranet only to people who are members of
the same company or organization.
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
EXTRANET
• An Extranet is actually an Intranet that is partially accessible to authorized
outsiders. The actual server (the computer that serves up the web pages)
will reside behind a firewall. The firewall helps to control access between
the Intranet and Internet permitting access to the Intranet only to people
who are suitably authorized.
EXTRANET:
• An extranet is a private network that uses Internet protocols and the public
telecommunication system to securely share part of a business's information
or operations with suppliers, vendors, partners, customers, or other
businesses.
• An extranet can be viewed as part of a company's Intranet that is extended
to users outside the company.
• The same benefits that Web technologies have brought to corporate
Intranets are now starting to accelerate business between businesses.
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
• Extranets can be used to exchange large volumes of data, share product
catalogues, share news with trading partners, collaborate with other
companies on joint development efforts, jointly develop and share training
programs with other companies, provide or access applications between
companies, and much more.
• It may sound like a technology for geeks only. But many people use
extranets every day without realizing it--to track packaged goods, order
products from their suppliers or access customer assistance from other
companies.
• An extranet is a mechanism based on Internet and Web technology for
communicating both privately and selectively with your customers and
business partners.

1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
USES OF EXTRANET:
• When done correctly, extranets provide a safe way to allow transactional
business-to-business activities and can save your company some serious
time and money.
• The automotive industry uses extranets to cut down on its redundant
ordering processes and keep suppliers up to date on parts and design
changes, allowing quicker response times to suppliers' problems and
questions.
• Suppliers can receive proposals, submit bids, provide documents, even
collect payments through an extranet site.
• An extranet has restricted (password-protected) access, so it may be
connected directly to each party's internal systems.
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
DISADVANTAGES:
• The benefits of extranets, such as reduced time to market and cost of doing
business, and faster access to partner information, may be outweighed by the
costs-security, Web servers and development, legacy systems integration,
ongoing support and maintenance.
• Extranets require a large amount of IS time and energy, much more than what
it takes to get an intranet or Web site up and running, which may place it at
the bottom of the IS group's to-do list.
CONCLUSION:
• A mix of each is most likely, Connect to partners, suppliers, customers in the
best way that supports your specific business model. "extranet" is helpful
conversationally when considering giving external parties access to enterprise
systems. The term should engender a deeper level of consideration and
concern regarding maintaining security and managing external relationships.

MOBILE COMMERCE - INTRODUCTION
• Mobile commerce (also known as mobile ecommerce, m-commerce and
other variations) consists of two primary components. The first is the ability
to use a wireless phone or other mobile device to conduct financial
transactions and exchange payments over the Internet.
• The second is the ability to deliver information that can facilitate a
transaction -- from making it easy for your business to be "found" via a
mobile Web browser to creating mobile marketing campaigns such as text
promotions and loyalty programs.
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
WHAT ARE THE ADVANTAGES AND DISADVANTAGES
MOBILE COMMERCE?
The advantage of m-commerce is:
• 1- Providing wider reach.
• 2- Reducing transaction cost
• 3- Streamline business processes.
• 4- Competitive pricing.
• 5- Reducing time to order.
The disadvantages of m-commerce
• 1- Small screens of most devices still limit types of file and data transfer (i.e. streaming videos,
etc.)
• 2- Standards guiding applications and technology development and connection(s)
• 3- WAP and SMS limited to small number of characters and text.
1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
• 4- Use of graphics limited
• 5- Less functionality for mobile Internet over mobile phones and existing generation of
handhelds than for mobile computers (laptops and next generation handhelds)
• 6- User interface is often difficult to learn how to use
• 7- Limited bandwidth
• 8- Limited roll out of higher bandwidth mobile networks and devices (i.e. 3g networks
and wireless broadband networks are predominantly located in cities)
• 9- Cost of establishing mobile and wireless broadband infrastructure
• 10- Technology constraints of mobile devices (memory, processing power, display
capabilities, input methods)
• 11- Security of data moved across some mobile and wireless networks
• 12- Businesses investment in hardware and infrastructure is seen as riskier as rapid
evolution of mobile and wireless technologies continues.

HUBS AND SWITCHES
Switch is a device in networks that filters and forwards packets between Local Area Network (LAN)
segments. Switches operate at the data link layer and sometimes that network layer of the Open system
Interconnection (OSI) reference model and therefore support any packet protocol. LANs that use switches to
join segments are called switched LANs or in the case of Ethernet networks , switched Ethernet LANs. A special
type of network device called the hub can be found in many small business networks. In computer networking,
hub is a small, simple, inexpensive device that joins multiple computers together.
3. GATEWAYS
A node in a network that serves as an entrance to another net Web pages. In homes, the gateway is the ISP
that connects the user and fire wall. The gateway is also associated with both a router which use headers and
forwarding tables to determine where packets are sent and a switch which provides the actual path for the packet
in an out of the gateway. Gateways are also called as protocol converters and can operate at any layer. The job
of gateway is any more complex than that of a router or switch.

  • 2. • Electronic commerce is an emerging concept that describes the process of buying and selling or exchanging of products, services and information via, Tele- communication and computer networks including the internet. • Electronic commerce needs a network infrastructure to transport the content- data, audio, visual, text, animation and so on. This network infrastructure is provided by what is known as the I-way or information super highway. ELECTRONIC COMMERCE 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 3. COURSE OUTLINE • Introduction to information superhighway, • Components of the I-way, • Internet as network infrastructure, TCP/IP Protocol suite, Intranet, Extranet etc • Software agents (static and dynamic), • Broadband technologies (xDSL, Wi-Fi, WAN). 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 4. INTRODUCTION TO I-WAY • The I-way has emerged as the basic network infrastructure for all types of E- commerce activities due to its capability to provide integrated voice ,data and video services . I-way has changed the way business advertises, market or sell their products and services. This paper highlights the network infrastructure in E-Commerce. • A physical network, an infrastructure of modern high-speed links links everyone at home or office to everything else in practicality it is identical to internet provided -connections are broadband -they are continuously running as internet develops into I-way, changes will take place in infrastructure not in internet 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 5. INTERNET AND INTRANET BASED E- COMMERCE- ISSUES, Internet • This is the world-wide network of computers accessible to anyone who knows their Internet Protocol (IP) address - the IP address is a unique set of numbers (such as 209.33.27.100) that defines the computer's location. Intranet • This is a network that is not available to the world outside of the Intranet. If the Intranet network is connected to the Internet, the Intranet will reside behind a firewall and, if it allows access from the Internet, will be an Extranet. The firewall helps to control access between the Intranet and Internet to permit access to the Intranet only to people who are members of the same company or organization. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 6. EXTRANET • An Extranet is actually an Intranet that is partially accessible to authorized outsiders. The actual server (the computer that serves up the web pages) will reside behind a firewall. The firewall helps to control access between the Intranet and Internet permitting access to the Intranet only to people who are suitably authorized. EXTRANET: • An extranet is a private network that uses Internet protocols and the public telecommunication system to securely share part of a business's information or operations with suppliers, vendors, partners, customers, or other businesses. • An extranet can be viewed as part of a company's Intranet that is extended to users outside the company. • The same benefits that Web technologies have brought to corporate Intranets are now starting to accelerate business between businesses. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 7. • Extranets can be used to exchange large volumes of data, share product catalogues, share news with trading partners, collaborate with other companies on joint development efforts, jointly develop and share training programs with other companies, provide or access applications between companies, and much more. • It may sound like a technology for geeks only. But many people use extranets every day without realizing it--to track packaged goods, order products from their suppliers or access customer assistance from other companies. • An extranet is a mechanism based on Internet and Web technology for communicating both privately and selectively with your customers and business partners. Contd… 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 8. USES OF EXTRANET: • When done correctly, extranets provide a safe way to allow transactional business-to-business activities and can save your company some serious time and money. • The automotive industry uses extranets to cut down on its redundant ordering processes and keep suppliers up to date on parts and design changes, allowing quicker response times to suppliers' problems and questions. • Suppliers can receive proposals, submit bids, provide documents, even collect payments through an extranet site. • An extranet has restricted (password-protected) access, so it may be connected directly to each party's internal systems. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 9. DISADVANTAGES: • The benefits of extranets, such as reduced time to market and cost of doing business, and faster access to partner information, may be outweighed by the costs-security, Web servers and development, legacy systems integration, ongoing support and maintenance. • Extranets require a large amount of IS time and energy, much more than what it takes to get an intranet or Web site up and running, which may place it at the bottom of the IS group's to-do list. CONCLUSION: • A mix of each is most likely, Connect to partners, suppliers, customers in the best way that supports your specific business model. "extranet" is helpful conversationally when considering giving external parties access to enterprise systems. The term should engender a deeper level of consideration and concern regarding maintaining security and managing external relationships. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 10. E-COMMERCE, PROBLEMS AND PROSPECT • Large resource requirement. • Alliance between communication, entertainment, and information sectors. • Alliance to reduce risks, spread costs and acquire costly expertise in different area instantly. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 11. COMPONENTS OF I-WAY • NETWORK ACCESS EQUIPMENT • hardware and software vendors: who provide • set-top boxes • computers • switches, hubs, routers • software platforms such as browser operating systems 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 12. COMPONENTS OF I-WAY LOCAL ON-RAMPS • wiring linking homes with backbone • requirement of huge investment • also known as “last mile” • divided into four categories: • telecom based infrastructure • cable tv-based infrastructure • wireless infrastructure • commercial online infrastructure 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 13. MOBILE COMMERCE - INTRODUCTION • Mobile commerce (also known as mobile ecommerce, m-commerce and other variations) consists of two primary components. The first is the ability to use a wireless phone or other mobile device to conduct financial transactions and exchange payments over the Internet. • The second is the ability to deliver information that can facilitate a transaction -- from making it easy for your business to be "found" via a mobile Web browser to creating mobile marketing campaigns such as text promotions and loyalty programs. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 14. WHAT ARE THE ADVANTAGES AND DISADVANTAGES MOBILE COMMERCE? The advantage of m-commerce is: • 1- Providing wider reach. • 2- Reducing transaction cost • 3- Streamline business processes. • 4- Competitive pricing. • 5- Reducing time to order. The disadvantages of m-commerce • 1- Small screens of most devices still limit types of file and data transfer (i.e. streaming videos, etc.) • 2- Standards guiding applications and technology development and connection(s) • 3- WAP and SMS limited to small number of characters and text. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 15. • 4- Use of graphics limited • 5- Less functionality for mobile Internet over mobile phones and existing generation of handhelds than for mobile computers (laptops and next generation handhelds) • 6- User interface is often difficult to learn how to use • 7- Limited bandwidth • 8- Limited roll out of higher bandwidth mobile networks and devices (i.e. 3g networks and wireless broadband networks are predominantly located in cities) • 9- Cost of establishing mobile and wireless broadband infrastructure • 10- Technology constraints of mobile devices (memory, processing power, display capabilities, input methods) • 11- Security of data moved across some mobile and wireless networks • 12- Businesses investment in hardware and infrastructure is seen as riskier as rapid evolution of mobile and wireless technologies continues.

  • 16. WORLD WIDE WEB • Motivation: Developing a global distributed hypermedia system. • Started 1989 by a research paper issued by Tim Berners-Lee who worked at the CERN. • 1993: First usable browser (MOSAIC) issued. • 1994: Foundation of World Wide Web Consortium (W3C).– W3C then started developing HTML, HTTP and Style Sheets. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
  • 17. HUBS AND SWITCHES Switch is a device in networks that filters and forwards packets between Local Area Network (LAN) segments. Switches operate at the data link layer and sometimes that network layer of the Open system Interconnection (OSI) reference model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or in the case of Ethernet networks , switched Ethernet LANs. A special type of network device called the hub can be found in many small business networks. In computer networking, hub is a small, simple, inexpensive device that joins multiple computers together. 3. GATEWAYS A node in a network that serves as an entrance to another net Web pages. In homes, the gateway is the ISP that connects the user and fire wall. The gateway is also associated with both a router which use headers and forwarding tables to determine where packets are sent and a switch which provides the actual path for the packet in an out of the gateway. Gateways are also called as protocol converters and can operate at any layer. The job of gateway is any more complex than that of a router or switch. 1/9/2017 ABHISHEK SRIVASTAVA(CSE)JIT
