1

the maximum rate at which data can be carried over a specific medium

bandwidth

2

the actual amount of data, in bits, that crosses a given point in a network over a certain period of time

throughput

3

the amount of usable data that crosses a given point in a network over a certain period of time

goodput

4

interference that is caused when the electromagnetic field of one device affects the electromagnetic field of other devices

electromagnetic interference

5

electromagnetic interference that is in the radio frequency range

radio frequency interference

6

occurs when the signals of one wire affect the signals on an adjacent wire

crosstalk

7

the twisting of opposing wires to effectively eliminate crosstalk

cancellation

8

information that is added before the data field in a frame

header

9

information that is added after the data field in a frame

trailer

10

the actual connections and layout of devices in a network

physical topology

11

the way that the data travels through the network

logical topology

12

nodes compete to be able to use the network medium

contention-based access

13

when each node has an orderly opportunity to access the medium

controlled access

14

value of the field in a frame that is computed from the contents of the frame and determines if the frame has been damaged

frame check sequence

15

devices are able to send and receive data simultaneously

full-duplex

16

devices are able to send and receive information, but only one direction at a time.

half-duplex
