Vocabulary Exercise: Matching
Definition
a. Ethernet’s collision resolution methodology
b. the fading of a data signal as it travels
through the media
c. reading the entire frame to check for errors
before sending on to the destination
d. filters traffic at Layer 3; segments broadcast
domains
e. Layer 2 device that provides network access
to hosts
f. Layer 2 error-checking mechanism
g. capable of simultaneous transmission and
reception
h. basic unit of time in which one bit can be
sent
i. multiport repeater or LAN concentrator
j. sending a frame out all ports except for the
port it was received on
k. frames are stored in queues that are linked to
specific incoming ports`
l. temporary, dedicated path between two hosts
created by the switch
m. sending out frames as soon as the destination
MAC address is read
n. deposits all frames into a common memory
buffer
o. address contained within the frame header
for Ethernet encapsulations
p. sending a frame out a port based on the unicast
MAC address
q. filters traffic based on Layer 2 addressing; no
longer used in today’s networks
r. forwarding frames after the first 64 bytes are
read
s. delay inherent in sending data from the
source to the destination
t. area of a LAN where frames from two different
sources can run into each other
u. can either send or receive, but not both at the
same time
v. filters traffic at Layer 2; capable of microsegmentation
