JNTU B.Tech IV E-COMMERCE Previous Question Paper (May - 2019 - R15)

The i-way, or information highway, refers to the high-speed telecommunications infrastructure and digital networks that facilitate the rapid transmission of data, voice, and video globally. It serves as the fundamental backbone for e-commerce, enabling the seamless exchange of information between businesses, consumers, and government entities.

The "last mile" refers to the final leg of a telecommunications network that delivers connectivity to the end user. The primary types of last mile connections include:

• Digital Subscriber Line (DSL): Utilizes existing copper telephone lines to provide high-speed data transmission alongside voice services.
• Cable Modem: Leverages the coaxial cable infrastructure originally designed for television to deliver broadband internet access.
• Fiber to the Premises (FTTP/FTTH): Uses optical fiber cables to provide high-bandwidth, low-latency connectivity directly to the user's location.
• Wireless Local Loop (WLL): Employs radio frequency signals, such as Wi-Fi, WiMAX, or 5G, to establish a connection without physical cabling to the end user.
• Satellite: Provides connectivity via satellite links, typically used in remote or rural areas where terrestrial infrastructure is unavailable.
