Question 1

Bus TopologyChapter 1 Page 12

Answer 1

Bus is the most basic topology. Consists of two distinct and terminated ends, with each of it/s computers connecting to one unbroken cable with wire taps, but this didn’t work all that well so we began using drop cabled in their place.

Question 2

Star TopologyChapter 1 Page 13

Answer 2

Computers are connected to a central point with their own individual cabled or wireless connections. The center spot is often inhabited by a device like a hub, switch, or an access point.

Question 3

Ring TopologyChapter 1 Page 14

Answer 3

Each computer is directly connected to other computers within the same network.

Question 4

Mesh TopologyChapter 1 Page 15

Answer 4

There’s a path from every machine to every other one in the network.

Question 5

Point to Point TopologyChapter 1 Page 16

Answer 5

Direct connection between two routers or switches, giving you one communication path. Routers in a point to point can be linked by a serial cable, making it a physical network.

Question 6

What is a drawback to peer-to-peer network sharing?Chapter 1 Page 16

Answer 6

It’s not very scalable.

Question 7

What type of networks are most commonly seen in today’s WAN’s?Chapter 1 Page 17

Answer 7

Point-to-point.

Question 8

Point to Multipoint TopologyChapter 1 Page 17

Answer 8

Consists of a succession of connections between an interface on one router and multiple destination routers. one point of connection to multiple points of connection.

Question 9

What are some of the most important questions to ask oneself when selecting which type of network to rely upon?Chapter 1 Page 19

Answer 9

What is budget?How much fault tolerance and security do I need?Is this network going to quickly grow?Will I need to quickly and easily reconfigure often?How scalable does my network need to be?

Question 10

Backbone vs SegmentsChapter 1 Page 20

Answer 10

The network backbone is what all of the segments and servers connect to and what gives your network structure. Segments are any small section of a network that may be connected to, but actually isn’t a piece of the backbone.

Question 11

T/FIn a bus topology, data is transmitted to all computers in the network where they can see it? Chapter 1 Page 13

Answer 11

False. Data flows through the computers but only the computer it’s addressed to actually receives it.

Question 12

What is the single point of failure in a star topology?Chapter 1 Page 14

Answer 12

The hub or central device.

Question 13

What technology at an ISP might still use a ring topology?Chapter 1 Page 15

Answer 13

SONET.

Question 14

How many connections must be connected in a population of 10 computers in a mesh topology?Chapter 1 Page 16

Answer 14

45. The amount of cabling is why most corporate LANs haven’t use them, because they were so complicated to manage.

Question 15

What is a hybrid topology?Chapter 1 Page 18

Answer 15

A combination of two or more types of physical or logical network topologies working together in the same network.
