3d Bandwidth

Question 0

Describe how different communication media affect the bandwidth available when transferring files.

Answer 0

 different media have different bandwidths (1) and
therefore different data carrying capabilities (1)
 capacity of the medium (1) affected by factors such
as signal strength and noise (1)
 the more data that can travel across the bandwidth
the higher the risk of collision and error (1) requiring
retransmission and increased network traffic (1)  the higher the data rate of a particular medium
results in more data transmission (1) in a given time (1) freeing bandwidth for subsequent transmission (1)

Question 1

Define the term bandwidth

Answer 1

 a measurement of the volume of data (1) per
second (1)
 rate of transmission (1) in bps (1)
 the difference between the maximum and minimum
frequency of signal (1) that a communications
channel can carry (1)
 measure of the capacity (1) of a
network/communications channel (1)
 maximum amount of data (1) in a given time (1)

Question 2

Answer 2

infrared

wireless

cable
