Chapter 5: Topologies Of Ethernet Standards

Question 1

Access Method

Answer 1

A networks method of controlling how nodes access the communications channel.

Question 2

Active Topology

Answer 2

A topology in which each workstation participates in transmitting data over the network. A ring topology is considered an active topology.

Question 3

Broadcast Domain

Answer 3

Logically grouped network nodes that can communicate directly via broadcast transmissions. By default, switches and repeating devices such as hubs extend broadcast domains. Routers and other layer 3 devices separate broadcast domains.

Question 4

Bus

Answer 4

The single cable connecting all devices in a bus topology.

Question 5

Bus Topology

Answer 5

A topology in which a single cable connects all nodes on a network without intervening connectivity devices.

Question 6

Carrier Ethernet

Answer 6

A level of Ethernet service that is characterized by very high throughput and reliability and is used between carriers, such as NSPs.

Question 7

Circuit Switching

Answer 7

A type of switching in which a connection is established between two network nodes before they begin transmitting data. Bandwidth is dedicated to this connection and remains available until users terminate the communication between the two nodes.

Question 8

Collapsed Backbone

Answer 8

A type of backbone that uses a router or switch as the single central connection point for multiple sub networks.

Question 9

Collision

Answer 9

In Ethernet networks, the interference of one nodes data transmission with the data transmission of another node sharing the same segment.

Question 10

Collision Domain

Answer 10

The portion of an Ethernet network in which collisions could occur if two nodes transmit data at the same time. Switches and routers separate collision domains.

Question 11

Daisy Chain

Answer 11

A group of connectivity devices linked together in a serial fashion.
