Comments
Guaranteed unique address, assigned by the
Internet Corporation for Assigned Names and
Numbers (ICANN). IP address includes four
"octets" (eight bits, translating to integers from 0 to
255), separated by periods.
ICANN assigns three classes of addresses:
Class A – first (leftmost) octet is assigned; the
three rightmost octets are assignable to the owner
of the Class A address.
Class B – first and second (leftmost) octets are
assigned, the remaining two are assignable by the
owner of the Class B address
Class C – the three leftmost octets are assigned;
only the rightmost octet is user-assignable. The
number 0 is reserved for router connections to
another network, 127 for loopback testing, and 255
for broadcast to all computers on the network.
Digital service provided by telephone companies.
Caused by a failed Network Interface Card, or by a
computer device that transmits packets whose
length violates network rules.
Transmission speed.
Networked devices, logically isolated from other
networks and devices.
Layer 2 of the OSI Model
Ethernet Interface (transceiver, software to
physical media)
Unique code "burned" into firmware by the device
manufacturer.
(Also see AUI, MDI, MAC)
Physical connector at cable end (e.g., RJ-45 plug
on Ethernet CAT 5 cable.) (Also see AUI, MAU)
