Twisted pair and coaxial are covered with plastic. What are two common “grades” or types of plastic that you can purchase with these cable types?
PVC or Plenum
Why might you choose a plenum type cable?
Because you are worried about the risk of fire
What are two common coax RG types?
RG-6 and RG-59
Between RG-6 and RG-59, which coax cable has the thicker core?
RG-6
About how long can RG-6 be run in feet?
About 1000 feet
Where do we often see RG-6 in our home?
For cable telelvision and cable modem connections
What component do you use with coax cable when you want to run many different feeds from a single connection?
A splitter
Why might a splitter cause a problem in a coax environment?
The signal can degrade when you add splitters to the topology
What are two common coaxial connectors that you should know?
The BNC type and the F-connector
What is the most popular type of network cabling in use in the world today?
Twisted Pair
What are the two major forms of twisted pair?
Unshielded Twisted Pair and Shielded Twisted Pair (UTP and STP)
What are there twists in UTP?
The twists are used to reduce the interference
What are the two categories of UTP that are so old, we typically no longer encounter them in networks today?
Cat 3 and Cat 4
What is the maximum transmission distance for UTP?
100 meters (328 feet)
What is the first category of UTP that can transmit at 100 Mbps?
Category 5 (Cat5)
