Verified Correct Answers
Application Layer (7th layer)
Interacts with application programs that incorporate a
communication component such as your Internet
browser and email (provides user interface)
Bus Topology
The computers share the media (coaxial cable) for data
transmission
CAT6 (category 6)
Twisted-pair cables capable of carrying up to
1000Mbps (1 gigabit) of data up to a length of 100
meters
Crossover
Transmit and receive signal pairs are crossed to
properly align the transmit signal on one device with
the receive signal on the other device
CSMA/CD
Carrier sense multiple access with collision detection is
the Ethernet LAN media-access method (used to
prevent collisions in wired Ethernet networks) Used in
wireless networks for to reduce collisions.
,Data Link Layer (2nd layer)
Layer of the OSI reference model that handles error
recovery, flow control (synchronization), and
sequencing (controls which terminals are sending and
receiving. Media access is controlled by the Data Link
Layer
Deterministic
Access to the network is provided at fixed time
intervals
Ethernet, Physical, Hardware, or Adapter Address
Other names for MAC address
Firewall Protection
Used to prevent unauthorized access to your network
Host Address
Same as host number
Host Number
The portion of the IP address that defines the location
of the networking device connected to the network;
also called the host address
Hotspots
A limited geographic area that provides wireless access
for the public
,Hub
Broadcasts the data it receives to all devices connected
to its ports... it is possible for network devices to pick
up a data intended for a different device... considered
a multiport repeater
IANA
The Internet Assigned Numbers Authority is the agency
that assigns IP addresses to computer networks
ICMP
Internet Control Message Protocol (perform
diagnostics, report errors, control the flow of data in
the network)
IEEE
Institute of Electrical and Electronics Engineers, one of
the major standard-setting bodies for technological
development
Intranet
An internal network that provides file and resource
sharing but ifs not accessed from the Internet
IP Address
Unique 32-bit address that identifies on which
network the computer is located as well as
, differentiates the computer from all other devices on
the same network; they are logical addresses and can
be found using the ipconfig/all command
IP Internetwork
A network that uses IP addressing for identifying
devices connected to the network
ipconfig/all
Enables the MAC address information to be displayed from the command prompt
ISP
Internet service provider
Link Integrity Test
Protocol used to verify that a communication link
between two Ethernet devices has been established
Link Light
Indicates that the transmit and receive pairs are
properly aligned
Link Pulses
Sent by each of the connected devices via the twistedpair
cables when data is not being transmitted to
indicate that the link is still up
Local Area Network (LAN)
