Question 8

Twisted Pair Cable

Answer 8

the oldest cable type with two or more insulated copper wires that are twisted around each other and are enclosed in another layer of plastic insulation

Question 9

A wire that carries an electric current…

Answer 9

generates an electromagnetic field around itself. The electromagnetic field can induce a small flow if electricity in nearby objects, including other wires.

Question 10

Electrical Interference

Answer 10

the induced flow of unwanted electricity

Question 11

Category 1 Cable

Answer 11

the type of twisted pair cable that telephone companies have used for years to transmit voice signals

Question 12

Coaxial Cable

Answer 12

an insulated copper wire encased in a metal shield that is enclosed in plastic insulation and is 20 times faster than Category 1

Question 13

Category 5 Cable

Answer 13

carries signals between 10 and 100 times faster than coaxial cable and is just as easy to install as Category 1 cable

Question 14

Category 5e (e stands for enhanced), Cat 6, and Cat 7 cable

Answer 14

are three newer versions of twisted cable that are constructed of higher quality materials so they can carry more signals up to 10 to 100 times faster than Cat 1 cable

Question 15

Fiber-optic Cable

Answer 15

“fiber” does not use an electrical signal; it transmits information by using lasers to pulse beams of light through very thin strands of glass, is immune to electrical interference, is the fastest, lighter, more durable, and the most expensive cable type
