2. What is i-way?
E-commerce is associated with the buying and selling of information, products, and services via computer networks today and in the future via any one of the myriad of networks that make up the information superhighway (i-way).
3. What is cross-media convergence?
Cross-media convergence refers to the integration of various industries—
entertainment, publication, and communication media—based on multimedia
content.
4. List some simple technological advances that drive the phenomenon of
convergence?
· Convergence of content
· Convergence of transmission
· Convergence of information access
5. List some components of multimedia?
Some components of multimedia are: text, audio, video, images,
animation, graphics, hologram, and numerical data.
6. What is message passing?
The client-server model allows the client to interact with the server through a request –reply sequence governed by a paradigm known as message passing.
7. List some challenges that each highway route provider faces?
· Telecom-based
· Cable-based
· Computer Network-based
· Wireless

9. What is a terminal equipment?
Customer Premises Equipment(CPE) or terminal equipment is a generic term for privately owned communications equipment that is attached to the network.
10. List some drawbacks of ADSL?
Asymmetric digital subscriber line has the following drawbacks: It cannot handle live transmissions, and the picture it produces is not as clear as that provided by a well-tuned cable hookup.
11. What is fast packet switching?
The bundles of data, known as packets move through a network at very high speeds and this routing technique is known as fast packet switching.
12. List the 4 types of “last mile” connections?
The four types of last mile connections are: plain old telephone system (POTS) wires, cable TV coaxial cable, electricity wires, and wireless.
13. What is HDT?
The digital video signals from all providers are combined on a video distribution element known as host digital terminal (HDT).
14. Give two advantages of DBS?
Two advantages of Direct Broadcast satellite are:
· Availability
· Affordability
15. List the two types of DBS available?
· PrimeStar DBS service
· Direct Satellite Service
16. List some major issues that will play a crucial role in defining the i-way?
The major issues are: cost, subsidies, allocation of scarce resources, regulation, universal access, privacy, and social issues.
17. What is a Network Access Point?
A NAP is a high speed network or switch to which a number of routers can be connected for the purpose of traffic exchange and interoperation.
18. What is a routing arbiter?
A Routing Arbiter (RA) is an element that is introduced into the NAP
architecture. RA organization implements the concept of policy-based network routing that enables routing of traffic between different network operators.
19. List the goals of Gigabit Network Research?
There are two goals:
