Question 1

Because the telephone system uses DC, it is standard practice to use the 'ring' as the ____________________ conductor.

Accepted Answer

The answer of Because the telephone system uses DC, it...

Question 2

_______ ensures that basic continuity and correct terminations have been applied, but does not attempt to measure the information-carrying capacity of the cable runs like you would do in a commercial installation

Accepted Answer

Verification ensures that basic continuity and correct terminations have been applied, but it does not test for the information-carrying capacity of the cables. Certification, on the other hand, tests and measures the cable's information-carrying capacity and ensures that it meets industry standards. Inspection is a general term that can refer to checking for any physical damage or defects in the cable. Attenuation refers to the loss of signal strength that occurs as the signal travels along the cable.

Question 3

A(n) ____________________ is the smallest unit of measure in the binary system.

Accepted Answer

The answer of A(n) ____________________ is the smallest unit of...

Question 4

A(n) ____________________ block is the connecting block that terminates UTP cables directly using IDC connections.

Question 5

A __________ is the hub of a structured wiring system and is usually located in the basement or garage. It is sometimes called a 'distribution center'.

Accepted Answer

A service center acts as the central point in a structured wiring system, distributing various services throughout a building from a common location, often found in basements or garages.

Question 6

It is a good idea to use 75-ohm F-Type __________ in each unused television outlet and at each unused splitter port throughout a house.

Accepted Answer

Termination caps are specifically designed to prevent signals from escaping or causing interference at unused outlets or splitter ports. Dust caps and plugs may protect the connection from debris but do not offer the same level of signal isolation. Jacks are not applicable in this context as they are used to make a connection rather than terminate one.

Question 7

When running voice, video or data cables along framing members in a basement, it is a good idea to use __________ instead of staples.

Accepted Answer

J-hooks provide a secure and organized way to run cables along framing members, without damaging the cable or interfering with the performance. Nails can damage the cable and should be avoided, loops are not typically used in this application, and VVD couplings are not a relevant option for cable routing.

Question 8

When installing voice, video and data wiring in a house, Articles __________ and __________ of the NEC contain some requirements that must be followed.

Accepted Answer

The answer of When installing voice, video and data wiring...

Question 9

When installing voice, video and data jacks throughout a house, the preferred piece of equipment used to mount the jacks in a wall is a __________.

Accepted Answer

Mud rings, also known as plaster rings, are preferred for mounting voice, video, and data jacks in walls because they provide a stable, flush surface for the installation without the need for a full enclosure, allowing for easier cable management and access.

Accepted Answer

The answer of The color coding for a 4-pair UTP...

Question 18

The decrease in the power of a signal as it passes through a cable, which is measured in decibels is _________.

Accepted Answer

The term used to measure the decrease in power of a signal as it passes through a cable is attenuation. It is measured in decibels. Choice A (exaggeration) is incorrect as it does not relate to the decrease in power of a signal. Choice C (bandwidth) refers to the range of frequencies that can be transmitted through a communication channel. Choice D (megahertz) is a unit of measurement for frequency.
