This document discusses information infrastructure at national, regional, and global levels. It defines information infrastructure as the communications networks and software that support interaction between people and organizations. A national information infrastructure provides integrated services for education, business, government through networks like computers, televisions, telephones and satellites. A regional information infrastructure is confined to a specific geographical region. The global information infrastructure aims to link the world's telecommunication and computer networks to support digital communication applications. The role of libraries is also discussed as central to the development of information infrastructure.

communications networks and associated software
that support interaction among people and
organizations. The Internet is the phenomenon that

6. LEVELS OF IFORMATIONN INFRASTRUCTURE
• NATIONAL
• REGIONAL
• GLOBAL

7. NATIONAL IFORMATIONN INFRASTRUCTURE(NII)
In recent years the subject of National Information Infrastructure (NII) has
been receiving greater attention in both scholarly and trade publications. The
issue is expected to have significant implications for the use of electronic
communication in education, business, industry, and government. The NII is
expected to provide for “ the integration of software, hardware and skills that
will make it easy and affordable to connect people with each other, with
computers, and with a vast array of services and information resources
FOR EXAMPLE-
“COMMUNICATION NETWORKS INCLUDING COMPUTERS, TELEVISIONS, TELEPHONES AND
SATELLITES” IS EXPECTED TO FOREVER ALTER THE WAY PEOPLE “LIVE, LEARN, WORK AND
COMMUNICATE WITH EACH OTHER BOTH WITHIN THE COUNTRY AND AROUND THE WORLD”.

8. REGIONAL INFORMATION INFRASTRUCTURE
• It has the same meaning as NII as regional information
infrastructure confined to specific geographical region
or a particular organization .
• For Example-
• NIC, the premier ICT organisation of Govt of India
• National Informatics Centre (NIC) is a premier
institution of the Government of India, established in
1976, for providing e-Government / e- Governance
Solutions adopting best practices, integrated services
and global solutions in Government Sector.

9. GLOBAL INFORMATION INFRASTRUCTURE(GII)
THE PRESENCE OF A GLOBAL INFORMATION INFRASTRUCTURE IS THAT
GOVERNMENT; BUSINESS COMMUNITIES, AND INDIVIDUALS CAN
COOPERATE TO LINK THE WORLD’S TELECOMMUNICATION AND
COMPUTER NETWORKS TOGETHER INTO A VAST CONSTELLATION
CAPABLE OF CARRYING DIGITAL AND ANALOG SIGNALS IN SUPPORT OF
EVERY CONCEIVABLE INFORMATION AND COMMUNICATION
APPLICATION.
FOR EXAMPLE- CONSTELLATION OF NETWORKS WILL PROMOTE AN INFORMATION SOCIETY
THAT BENEFITS ALL: PEACE, FRIENDSHIP, AND COOPERATION THROUGH INTERPERSONAL
COMMUNICATIONS; EMPOWERMENT THROUGH ACCESS TO INFORMATION FOR EDUCATION,
BUSINESS AND SOCIAL GOOD; MORE PRODUCTIVE LABOR THROUGH TECHNOLOGY-ENRICHED
ENVIRONMENTS; AND STRONGER ECONOMICS THROUGH OPEN COMPETITION IN GLOBAL
MARKETS.

10. GII ARCHITECTURE HAS 4 LAYERS
LAYER 4 User infrastructure
LAYER 3 Access infrastructure
LAYER 2 Application infrastructure
LAYER 1 Telecommunication infrastructure
GII application may be placed in the following categories:
• Entertainment
• Information Repository
• Trading and Commerce
• information Distribution

11. THE ROLE OF LIBRARIES IN INFORMATION
INFRASTRUCTURE
– Libraries are inherently information institutions
– Libraries rely heavily on computers and computer
networks, at least in developed countries.
– Considered central to the development of information
infrastructure in most countries,
– These challenges involve the following issues:-
1. Invisible infrastructure
2. Content and collections
3. Preservation and access
4. Institutional boundaries

12. CONCLUSION
.
To day information infrastructure is the
backbone of a developing countries. The
evolution of internet change the structure of
world. NEIS (Network Electronic Information
Society activities are center around networks
and the main commodity on the network is
electronic information in digital form. Benefits
of e-commerce are reduced cost ,increased
revenues, large costumer base, innovative
product& service and customer satisfaction
