TestOut Network Pro Ch 2 ExamQuestions and Answers
Two wires carry datasignals - Answer- one conductor carries a positive signal; the other
carries a negative signal. They are made of 22 or 24 gauge copper wiring
Plenum Cable - Answer- is fire resistant and non-toxic; it must be used when wiring
above ceiling tiles
PVC cable - Answer- cannot be used to wire above ceilings, because it is toxic when
burned.
Shielded Twisted Pair (STP) - Answer- has a grounded outer copper shield around the
bundle of twisted pairs or around each pair. This provides added protection against EMI.
Unshielded Twisted Pair(UTP) - Answer- does not have a grounded outer copper shield.
UTP cables are easier to work with and are less expensive than shielded cables.
Phone Cable(RJ11) - Answer- is used to connect a PC to a phone jack in a wall outlet to
establish a dial-up Internet connection. It has two pairs of twisted cable (a total of 4
wires).
Cat 3 (RJ45) - Answer- 3 is designed for use with 10 megabit Ethernet or 16 megabit
token ring.
Cat 5(RJ45) - Answer- supports 100 megabit Ethernet and ATM networking. Cat 5
specifications also support gigabit (1000 Mb) Ethernet
Cat 5e (RJ45) - Answer- is similar to Cat 5 but provides better EMI protection. It
supports 100 megabit and gigabit Ethernet.
Cat 6(RJ45) - Answer- supports 10 Gbps Ethernet and high-bandwidth, broadband
communications. Cat 6 cables often include a solid plastic core that keeps the twisted
pairs separate and prevents the cable from being bent too tightly.
Cat 6a(RJ45) - Answer- is designed to provide better protection against EMI and
crosstalk than Cat 6 cabling. Cat 6a provides better performance than Cat 6, especially
when used with 10 Gbps Ethernet.
, RJ11 - Answer- • Has 4 connectors
• Supports up to 2 pairs of wires
• Uses a locking tab to keep the connector secure in an outlet
• Used primarily for telephone wiring
RJ45 - Answer- • Has 8 connectors
• Supports up to 4 pairs of wires
• Uses a locking tab to keep the connector secure in an outlet
• Used for Ethernet and some token ring connections
Coaxial Cable - Answer- cable is an older technology that is usually implemented with a
bus topology. It is not suitable for ring or star topologies, because the ends of the cable
must be terminated. It is composed of two conductors that share a common axis within
a single cable
Coaxial Cable Advantages - Answer- • Highly resistant to EMI (electromagnetic
interference)
• Highly resistant to physical damage
Coaxial Cable Disadvantages - Answer- • More expensive than UTP
• Inflexible construction (more difficult to install)
• Unsupported by newer networking standards
Inner conductor( coaxial cable is built with) - Answer- carries data signals. It is made of
copper or copper coated with tin.
Mesh Conductor ( coaxial cable is built with) - Answer- conductor is a second physical
channel that also grounds the cable. It is made of aluminum or copper coated tin
Insulator (coaxial cable is built with) - Answer- surrounds the inner conductor and keeps
the signal separated from the mesh conductor. It is made of PVC plastic.
Mesh( coaxial cable is built with) - Answer- that surrounds the insulator and grounds the
cable. It is made of aluminum or copper coated tin.
Cable encasement( coaxial cable is built with) - Answer- surrounds and protects the
wire. It is made of PVC plastic.
RG 58 - Answer- Uses 10Base2 Ethernet networking (also called Thinnet) Resistance
rate; 50ohms
RG 59 - Answer- Uses Cable TV and cable networking Resistance rate; 75ohms
RG 6 - Answer- Uses Cable TV, satellite TV, and cable networking
RG-6 has less signal loss than RG-59 and is a better choice for networking applications,
especially when longer distances (over a few feet) are involved.
