11 List of Terms and Acronyms
10BaseT
10-Mbps baseband Ethernet specification using two pairs of twisted-pair
cabling (Category 3, 4, or 5): one pair for transmitting data and the other for
receiving data.
Address Resolution Protocol
. Internet protocol used to map an IP address to
a MAC address.
Connect One's
Internet extension to the industry-standard Hayes AT
command set. Supports simplified Internet connectivity commands in the
spirit of the AT syntax.
Encoding scheme
, which converts arbitrary binary data into a 64-character
subset of US ASCII. The encoded data is 33% larger than the original data.
Challenge Authentication Protocol.
Extends the PAP procedure by
introducing advanced elements of security.
Dynamic Host Configuration Protocol.
Provides a mechanism for allocating
IP addresses dynamically so that addresses can be reused when hosts no
longer need them.
Domain Name System
. Defines the structure of Internet names and their
association with IP addresses.
ARP
AT+i
TM
Base64
CHAP
DHCP
DNS
iChip
TM
Connect One’s Internet Controller for embedded Internet connectivity.
ICMP
Internet Control Message Protocol
. Network layer Internet protocol that
reports errors and provides other information relevant to IP packet processing.
Internet Protocol
. Provides for transmitting blocks of data, called datagrams,
from sources to destinations, which are hosts identified by fixed length
addresses. Also provides for fragmentation and reassemble of long datagrams,
if necessary.
Internet Protocol Control Protocol
. Establishes and configures the Internet
Protocol over PPP. Also negotiates Van Jacobson TCP/IP header compression
with PPP.
Internet Service Provider
. Commercial company that provides Internet
access to end (mostly PC) users through a dial-up connection.
Local Area Network
. High-speed, low-error data network covering a
relatively small geographic area (up to a few thousand meters).
Link Control Protocol
. Negotiates data link characteristics and tests the
integrity of the link.
Media Access Control.
Lower of the two sublayers of the data link layer
defined by the IEEE. The MAC sublayer handles access to shared media, such
as whether token passing or contention will be used.
Standardized data link layer address that is required for every port or device
that connects to a LAN. Other devices in the network use these addresses to
locate specific ports in the network and to create and update routing tables and
data structures. MAC addresses are 6 bytes long and are controlled by the
IEEE. It is represented as a 12-digit hexadecimal integer, where the first (left-
most) six digits are the Connect One company identification “000394”.
