E-com has become irrevocably linked with the idea of convergence of industries centered on information that until today has been isolated for content, storage, N/w, business applications and consumer devices. Convergence: Melding of consumer electronics, TV, Publishing, telecommunication, and computers for the purpose of facilitating new forms of information based commerce. Media convergence: It applies to the conversion of text, voice, data, image graphics and full motion video into digital content. Cross media convergence: It refers to the integration of various industries entertainment, publication and communication media-based on multimedia content. Phenomenon of convergence: Convergence of content: translates all types of information content- books, business dependent videos, musics -into digital information. Convergence of transmission: It compresses and stores digitized information so it can travel through existing phone and cable wiring. Which provides pipeline to transmit voice, data, image and video all without rewiring the neighborhood. Convergence of information access devices: have the sophistication to function as booth computer and TV. Condition for convergence: 1) widespread availability of increasingly low- cost, high-performance enabling component technologies, including semiconductors, storages & display devices, communication system, among others. 2) Aggressive regularity actions that are introducing competition in monopoly markets (local and long distance communication) 3) Aggressive regularity) media convergence Anatomy of E-Commerce applications E-Commerce applications are: 1.

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 _____________________________________________________________________________________ 4 PG Inter Departmental Course: Ecommerce Study Material --------------------------------------------------------------------------------------------------------------------- • 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. • Include 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
