Introduction History• 1994, Al Gore introduced the term.
-"Information Superhighway (will) allow us to share information, to connect, and to communicate as a global community".
Definition• High-capacity, interactive electronic pipeline providing
integrated services.
• The Information Superhighway is very much a physical network, an infrastructure of modern high-speed links.
Contd….
Links everyone at home or office to everything else.
The Information Superhighway is a physical network, facilitating the broadband, two-way transmission of any type of digital information, within its own virtual space.
Digitization 1. Integrity of the information2. Manipulation 3. Compression4. Convergence
Is internet information superhighway?
In practicality it is identical to internet provided
-connections are broadband-they are continuously running.
Broadband -ability to stack frequencies on a single transmission medium, providing
multiple channels on the same wire.-supports 150-750 kbps in both
upstream and downstream.
Contd….
-connections to internet must be able to support two way video communication as a broadband
enough.
Internet and infrastructure-As internet develops into I-way, changes will
take place in infrastructure not in internet.
Inernet and worldwide web(www)-it is possible to use internet without www.-explosion of the www made the internet I-way.
Market forces influencing I-way.
Demands and requirements of market participants.
• Users: becoming information publishers.
• Consumers, end users, or businesses:consuming information products/services.
• ISPs: commercial, government or private.
• Value added information providers: includes third party brokers, intermediaries, originators of services who add value to services provided by others.
Contd…
Strategic alliances and I-way infrastructure:
• Large resource requirement.
• Alliance between communication, entertainment, and information sectors.
• Alliance to reduce risks, spread costs and acquire costly expertise in different area instantly.
