Chapter 6 Student 12 Flashcards
NIC drivers operate where in the OSI model? Pg 285
In the Media Access control sublayer of the data link layer
What are the three main types of physical cabling used for networking? Pg 286
Coaxial, twisted pair, and fiber optic
Coaxial cable has a center conductor cord made of what substance? Pg 286
Copper
T or F, according to the Radio Guide system, the thicker the copper, the farther a signal can travel. Pg 286
True
When coax cable was popular for networking, they commonly used these two standards. Pg 286
RG 8 (thick net) and RG 58A/U (thin net)
Thick net used a special connector that has a metal tooth to dig into the cable, so that it has contact with the conductor. What is the name of this connector? Pg 287
Vampire Tap
Thinnet coax used these type of connectors to connect cables. What are they called? Pg 288
Male and Female BNC connectors
A coax cable that consists of several pairs of wire twisted around each other within an insulated jacket is known as what type ? Pg 288
Twisted pair
What are the two types of twisted pair coax cables? Pg 288
STP ( shielded twisted pair ) and UTP ( unshielded twisted pair )
What is the transfer speed of twisted pair Category 5e? Pg 289
Up to 1Gbps
What are the two standards used today for twisted pair cables with RJ 45 connectors? Pg 290
568A and 568B
T or F, a crossover cable will be the same on both ends. The pins cross over in the middle of the cable. Pg 291
False crossover cables are different on each end.
What is the maximum speed of Fiber Optics? Pg 291
10Gbps
Fiber optic cable comes in what two types? Pg 292
Single Mode Fiber (SMF) and Mulitmode Fiber (MMF)
What are the three fiber optic cable connector types? Pg 292-293-294
ST or straight tip, SC or subscriber connector, and LC or local connector
