1

The way that cables and other pieces of hardware connect to one another is called ____.

Network topology

2

Ways of connecting computers together are called ____.

Topologies

3

The first generation of wired networks used one of two topologies. They were called ____ and ____.

Bus and ring

4

What type of topology used a single cable that connects all the computers in a line?

Bus

5

What topology connects all computer on a network with a ring of cable?

Ring

6

What topology requires a termination at each end of a cable to prevent a signal sent from one computer from reflecting at the ends of the cable, quickly bringing the network down?

Bus

7

In what topology does data traffic move in a circle from one computer to the next in the same direction?

Ring

8

What problem did bud and ring topology networks suffer from?

Entire network stopped working if the cable broke at any point

9

What topology uses a central connection box for all the computers on the network?

Star

10

What is it called if one cable breaks and all the computers could still communicate?

Fault tolerance

11

How the cables physically look is called _____.

Physical topology

12

How the signal travels electronically is called ____.

Logical topology

13

Any form of networking technology that combines a physical topology with a signaling topology is called ____.

Hybrid topology

14

A network where every computer connects to every other computer via two or more routes is called _____.

Mesh topology

15

A network where at least two machines have redundant connections is called _____.

Partially redundant meshed topology

16

A network where every computer connects directly to every other computer is called _____.

Fully meshed topology

17

What is a practical application of a topology and other critical technologies that provides a method to get data from one computer to another on a network?

Network technology

18

Cabling that uses copper wire wrapped up in some kind of protective sheathing is called __.

Copper cable

19

What are the two primary types of copper cabling used in the industry?

1. Coaxial
2. Twisted pair

20

What type of cable contains a central conductor wire surrounded by an insulating material that is surrounded by a braided metal shield?

Coaxial cable

21

Coaxial cable shields data transmissions from ___.

Interference

22

Interference from one device to another, resulting in poor performance in the devices capabilities is called ___.

Electromagnetic interference (EMI)

23

What is a connector used for 10Base2 coaxial cable?

BNC connector

24

What is a screw-on connector used to terminate small-diameter coaxial cable such as RG-6 and RG-59?

F-connector

25

What type of coaxial cable is primarily for cable television rather than networking?

RG-59

26

What is the predominant coaxial cable type used today?

RG-6

27

What do you call a relative measure of the resistance of a coaxial cable?

Ohm rating

28

What describes a set of characteristics that define how much a cable resists the flow of electricity?

Impedance

29

What do you call how long it takes the wire to get a full charge?

Capacitance

30

What are the two types of twisted-pair cabling that are manufactured?

1. Shielded
2. Unshielded
