Fundamentals of Communication Flashcards
Define Baud rate
The number of signal changes in a
communication medium per second
A communication medium uses 8 bits per signal and
has a Baud rate of 128Bd. What is the medium’s bit
rate?
1024 bps
8 x 128 = 1024
In which method of data transmission is used for
transmitting data over medium to long distances?
Serial data transmission
What unit is used for bandwidth?
Hertz (Hz)
Define bandwidth
The range of frequencies that a
communication medium is capable of Transmitting
What should be the value of the stop bit
in the diagram below?
?011001010
stop bit start bit
1
Define latency
The difference in time between an action
being initiated and its effect being
noticed
Define Protocol
A set of rules relating to communication
between devices
Which method of data transmission is suitable for
transmitting information in real-time systems?
Synchronous data transmission
In which method of data transmission is data sent
one bit at a time over a single communication line?
Serial data transmission
In which method of data transmission do the sender
and receiver synchronise their clocks only for the
duration of data transmission?
Asynchronous data transmission
In which method of data transmission do numerous
parallel communication lines send multiple bits
between components simultaneously?
Parallel data transmission
What problem is caused by signals from tightly
packed communication lines leaking into others?
Crosstalk
In which method of data transmission is a clock
signal shared between the sender and receiver?
Synchronous data transmission
In which method of data transmission is used over
short distances?
Parallel data transmission
