5.5 Flashcards
Do you effectiveness of STP shield in twisted-pair depends on the following characteristics
Environment
Thickness and material used for the shield
Grounding mechanism
Symmetry and consistency of the ceiling
This cable line consists of one or more insulated wires pairs encased in a plastic she’s as its name implies it does not contain additional shielding for the twisted Paris as a result is both less expensive and less resistant to noise then STP
UTP
——-is more popular than STP due to the price. But cable prices have come down enough where it might only cost you a few extra pennies per foot for the better shielding
UTP
This cable grade is designed to withstand high temperatures such as would be experienced in an attic space it offers a high quality fire retardant jacket to reduce the spread of flames and areas with air circulation and it burns with less smoke that is non-toxic
Pelenium grade cable
Hey similar cable type is also coated with a fire retardant jacket and is he sick or cable to make it easier to push or pull through risers and buildings or between floors
Riser rated cable
 between STP And UTP Only STP can transmit at rates faster than 10 GB a second. This characteristic or factor is known as
Throughput
Both STP and UTP Use this type of connector
RJ 45 or registered Jack 45
T568 a wiring standard setup
GW/g/ow/B/BW/o/Brown white/brown
T568 be wiring
Orange white / orange / Green white/blue/blue white/orange/brown white/brown
The most common type of networking cable also called patch cable create one terminate the RG 45 plugs at both ends of the cable identically following one of the t568 standards
Straight through cable
Computers and routers are intended to send and receive signals on the wires as identified this port configurations called – – – – – and contrast switches use an alternate for configuration called – – – – –
Medium dependent interface MDI
MDI crossover MDIX
This cable has t568a standard on one end and t568b on the other
Crossover cable
This cable tribe has the transmit and receive wires reversed and was used to connect a computer to a computer or a switch to a switch
Crossover cable yeah yeah bitch you’re adorable do you realize how adorable you are
Unlike a crossover cable this cable over reverse the wire pen output regardless to how they are paired
Rollover cables also called consul cables
Released in 2003 as part of the ieee released at 802.3 AF standard which specifies a method of supply and logical power over twisted-pair ethernet connections
