5
A2A
Ease of maintenance Scalability Low cost of
installation
6
A2Q
Ethernet characteristics that led to its
widespread use
7
A3A

• Bandwidth can change
• Basically the same as 802.3
• Original idea came from Hawaii

8
A3Q

• What is Ethernet?

9
A4A
An increase in signal amplitude

A4Q
How are collisions detected?
11
A5A
It is the preferred mode. Auto-negotiation and
manual configuration are possible. Provides 200
Mbps throughput in 100BaseTx.

B4Q

What are the Protocol Data Units for each layer
of the OSI model?
21
B5A
The device that has priority to transmit after a
collision
22
B5Q
What is the first one in the collision domain
whose back-off timer expires?
23
C1A
Network devices that deal with frames.
24
C1Q
What are bridges and switches?
25

Adds these as part of the encapsulation process
at Layer 2.

What is CSMA/CD?
47
E3A
Deterministic Collisionless environment IEEE 802.5
48
E3Q
What is Token Ring?
49
E4A

• Transmitting and receiving packets (frames)
• Detecting errors within data packets (frames) or
  on the network
• Decoding packets (frames) and checking them for
  valid addresses before passing on to upper layers
  of the OSI model?

50
E4Q
What are functions of CSMA/CD?
51
E5A

• A collision is detected by all stations and
  backoff algorithm is invoked.
• Each transmitting station continues to transmit
  for a short time.
• After back-off timers stop, a workstation with
  data to transmit will listen and then transmit.

52
E5Q
What is the way that computers in an Ethernet
network respond to collisions?
