    2. Write the network access equipments?
    1) Cable TV Set top boxes
    2) Computer based telephony
    3) Hub, wiring closets and routers or digital switches.

    PART –B
    3. a) Write about E-Commerce framework.
    The architectural framework for e-commerce consists of six layers of
    functionalityor services as follows:
    1.Application services.
    2.Brokerage services, data or transaction management.
    3.Interface and support layers.
    4.Secure messaging, security and electronic document interchange.
    5.Middleware and structured document interchange, and
    6. .Network infrastructure and the basic communication services.
    1.Applications:
    In the application layer services of e-commerce, it is decided that what type of
    e-commerce application is going to be implemented. There are three types of
    distinguished e-commerce applications i.e., consumer to business application, business-to-
    business application and intra-organizational application.
    2.Information Brokerage and Management Layer:
    This layer is rapidly becoming necessary in dealing with the voluminous amounts of
    information on the networks. This layer works as an intermediary who provides
    service integration between customers and information providers, given some
    constraint such as low price, fast services or profit maximization for a client. For
    example, a person wants to go to USA from India.
    The person checks the sites of various airlines for the low-price ticket with the
    best available service. For this he must know the URLs of all the sites. Secondly, to search
    the services and the best prices, he also has to feed the details of the journey again and
    again on different sites.
    If there is a site that can work as information broker and can arrange the ticket as per
    the need of the person, it will save the lot of time and efforts of the person. This isjust
    one example of how information brokerages can add value.
    Another aspect of the brokerage function is the support for data management
    and traditional transaction services. Brokerages may provide tools to accomplish
    more sophisticated, time-delayed updates or future-compensating transactions.
    3.Interface and Support Services:
    The third layer of the architectural framework is interface layer. This layer provides
    interface for e-commerce applications. Interactive catalogs and directory support
    services are the examples of this layer.

    3. b) Write the multimedia content for E-commerce applications.


    Multimedia is the use of digital data in more than one format such a combination
    of text, audio, video, graphics in computer file.

    Multimedia is associated with the hardware convergence taking place in


    communication, computer and cable •industry as the next generation digital.

    Access to multimedia content depends on the hardware and software applications


    that run on it.
    The success of ecommerce applications also depends on variety and
    innovativeness of multimedia content and packaging. It includes television productions,
    traditional print productions, software and information services.

    Technical definition of multimedia is the use of digital data in more than one format,
    such as the combination of text, audio, video, images, graphics, numerical data,
    holograms, and animations in a computer file/document.

    iii. Video Servers & E-Commerce
    •Information Delivery/Transport & E-Commerce Applications
    •Consumer Access Devices

    Multimedia Content for E-Commerce Applications

    •Multimedia content can be considered both fuel and traffic for electronic commerce
    applications.

    •The technical definition of multimedia is the use of digital data in more than one format,
    such as the combination of text, audio, video, images, graphics, numerical data,
    holograms, and animations in a computer file/document. See in Fig.

    •The Accessing of multimedia content depends on the hardware capabilities of the
    customer.

    Multimedia Storage Servers & E-Commerce Applications

    •E-Commerce requires robust servers to store and distribute large amounts of digital
    content to consumers.

    •These Multimedia storage servers are large information warehouses capable of handling
    various content, ranging from books, newspapers, advertisement catalogs, movies,
    games, & X-ray images.

    •These servers, deriving their name because they serve information upon request, must
    handle large-scale distribution, guarantee security, & complete reliability

    i. Client-Server Architecture in Electronic Commerce

    •All e-commerce applications follow the client-server model

    •Clients are devices plus software that request information from servers or interact known
    as message passing

    •Mainframe computing , which meant for “dump”

    •The client server model, allows client to interact with server through request-reply
    sequence governed by a paradigm known as message passing.

    •The server manages application tasks, storage & security & provides scalability-ability
    to add more clients and client devices( like Personal digital assistants to Pc’s. See in fig.

    ii. Internal Processes of Multimedia Servers

    •The internal processes involved in the storage, retrieval & management of multimedia
    data objects are integral to e-commerce applications.

    •A multimedia server is a hardware & software combination that converts raw data into
    usable information & then dishes out.
    •It captures, processes, manages, & delivers text, images, audio & video.

    •It must do to handle thousands of simultaneous users.

    •Incude high-end symmetric multiprocessors, clustered architecture, and massive parallel


    systems.

    iii. Video Servers & E-Commerce

    The electronic commerce applications related to digital video will include

    1. Telecommunicating and video conferencing

    2. Geographical information systems that require storage & navigation over maps

    3. Corporate multimedia servers

    4. Postproduction studios

    5. shopping kiosks.

    •Consumer applications will include video-on-demand.

    •The figure which is of video–on demand consist video servers, is an link between the
    content providers (media) & transport providers (cable operators)

    Information Delivery/Transport & E-Commerce Applications

    •Transport providers are principally telecommunications, cable, & wireless industries.

    Information Transport Providers Information Delivery Methods


    Telecommunication companies long-distance telephone lines;
    local telephone lines
    Cable television companies Cable TV coaxial, fiber optic & satellite
    lines
    Computer-based on-line servers Internet; commercial on-line service
    providers
    Wireless communications Cellular & radio networks; paging systems
    Consumer Access Devices

    Information Consumers Access Devices

    •Computers with audio & video Personal/desktop computing,

    capabilities Mobile computing

    •Telephonic devices Videophone

    •Consumer electronics Television + set-top box Game systems

    •Personal digital assistants (PDAs) Pen-based computing, voice-driven computing
