Enhancing customer service delivery
Businesses that transform to the World Wide Web with an Internet presence and an e-commerce solution require an e-customer service and self-serve customer service delivery strategy.
TRUE OR FALSE
TRUE
Transmission method that uses a continuously variable signal, as opposed to digital transmission that uses two distinct signal values.
ANALOG
Device to automatically answer a telephone call, play a recorded message, and then record the caller’s message.
ANSWERING MACHINE
The rate of data transfer or throughput; a theoretical maximum capability of a specific physical medium.
BANDWIDTH
Device that generates a sound or effect when a caller calls a specific telephone number; also called a pager. Some beepers support sending short messages, either numeric, or voice, to the device.
BEEPER
Telecommunications signal of greater bandwidth than normal signals.
BROADBAND

BUSINESS TO CONSUMER – B2C
E-commerce model that describes activities that support business activities between commercial organizations and government agencies, also called public sector organizations. PSO.
BUSINESS TO GOVERNMENT – B2G
Transmission method that uses two distinct signal values, high and low, or 0 and 1, as opposed to analog transmission that uses a continuously variable signal.
DIGITAL
An automatic configuration protocol used to assign device attributes to devices on IP networks.
DYNAMIC HOST CONFIGURATION PROTOCOL – DHCP
The practice of doing business with remote customers over the Internet.
E-COMMERCE
Connection to a standard telephone line that allows a user to scan one or more pages of documents and send the scanned images to a fax machine connected to a telephone line in another location.
FACSIMILE DEVICE
The state of being in close proximity to multiple devices that are perpetually connected to the Internet.
HYPERCONNECTIVITY
A global network made up of interconnected networks that all use the standard Internet Protocol Suite –TCP/IP.
INTERNET

A numeric label assigned to each computer or device connected to a network that uses the Internet Protocol.
IP ADDRESS
The amount of time required for a message to reach its destination, measured in milliseconds (mSec).
LATENCY
Telephone that connects to the telephony network using radio transmission instead of wires.
