41. What is the difference between a network’s physical topology and its logical topology?
ANSWER:
The physical topology of a network refers to the way that all devices are physically
connected. It takes into account the way that the computers are cabled together and
whether they have a central connecting device or not. The logical topology of a
network refers to the way that the signals travel from one network device to another.
Although all the devices may appear to pass data in certain direction, the actual path
the data takes may be different-often it depends on the interconnecting device such as
a hub or switch.

42. In a physical bus topology, why do the ends of the cable have to be terminated?
ANSWER:
When data is sent onto the network in a physical bus topology, it continues to travel the
length of the network until it loses strength or until it is absorbed by a device. Once the signal
reaches the end of the cable, it will bounce back and interfere with the other signals that
follow it. To eliminate this signal distortion, the ends are terminated with a material that
absorbs the signal so that it cannot bounce back.

QUESTION TYPE:
Subjective Short Answer
HAS VARIABLES:
False
ANSWER:
A physical star is the easiest topology to setup and expand. You are only limited by
your available ports. You can easily expand the number of ports by adding yet
another device and forming an extended star. The centralized design makes
monitoring and managing network traffic easier. With a bus, the bandwidth is limited
to 10Mbps and half-duplex mode. A star can operate at much higher speeds and, if a
switch is used, is capable of operating in full-duplex mode. There is only one main
disadvantage-that is that the central device represents a single point of failure.

44. Describe the structure of an Ethernet frame.
ANSWER:
An Ethernet frame is composed of three parts. The first part is called the header. It contains
the source and destination MAC addresses along with a 2-byte type field. The type field is a
code that tells what network protocol is being used in the data portion of the frame. The
second part of the frame is the data portion, which is referred to as the payload. This is the
actual data that an application is sending across the network. The part also includes the
header from the network protocol. The last part of a frame is the FCS, which contains an
error-checking code called a CRC. It is the result of applying a mathematical formula to the
data portion of the frame. It is used to verify that the frame was not damaged in transmission.

45. What is CSMA/CD and how does it work?
ANSWER:
CSMA/CD is the media access method used by Ethernet, which is a set of rules that govern
how and when a device can transmit on an Ethernet network. When two devices transmit a
signal at the same time, they cause a collision to occur. Then the devices must try to transmit
again, and again, causing a bottleneck. To avoid these collisions, CSMA/CD says that a
device must first listen to see whether it can detect any other signal on the medium. If no
other signal is detected, then the device can transmit. If another device transmits at the same
time and a collision occurs, then both transmitting stations must wait for a random period
before they can try to transmit again.
