Are twisted pair wire and coxial cable the same?
No. Coaxial cable is a single wire that has a thick coating around it. A common use of coaxial cable is for cable television. This is the cable that goes from the jack on the wall into your cable box. Twisted pair contains multiple cables which are split into pairs and twisted together. CAT5/CAT5e/CAT6 cable are all examples of twisted pair. There are a total of 8 wires inside. Every two wires are twisted together to form a pair. The purpose of the cables being twisted together is to reduce electrical interference between the wires.
What is the T-568 A AND T-568 A Ethernet wire?
T-568A and T-568B are two types of wiring for the connectors on ethernet cables. Both standards work fine, but you can not intermix the two types of connectors on a single cable. You can have mixed cables on a network as long as each individual cable is wired the same on both ends. (Example, one patch cable uses t568a on both ends, a different cable uses t568b on both ends, and a third uses a matching, but different color pinout) Some cable is labeled 568a or 568b. This means that the 4 twisted pairs (for a total of 8 little cables) inside the jacketed ethernet cable is made for a certain type of connection. For example, cat 6 cable is higher quality, rated for up to 10GB network use. There are more twists per inch of those little wire pairs inside the jacket of the cable to help reduce crosstalk and interference. I have some cat 6 cable labeled 568b, and of the 4 twisted pairs, some have more twists then others. corresponding to what the data pairs are in the cable. I assume this is a cost cutting measure as more twists means more wire inside of those ethernet cables. Better quality cable should have equal amounts of twists per inch so that either 568a or 568b connections can be used without having to worry about what the cable specifies.
How many wire pairs in a cat 5 cable are actually used for transmission and reception on a 10 base t network?
Twisted pair cabling has 4 pairs of wires (8 wires in total), but 10BASE-T and 100BASE-TX requires only 2 of those pairs (4 wires in total).Exams will often try to trick you by asking questions like 10baseT uses how many pairs so you think you're being asked how many pairs does it have? When really you're just being asked how many pairs does it use.
What is a cat 5 cable and why is it used?
Cat-5 cable, sometimes called Ethernet cable, is short for Category 5 cable, a current industry standard for network and telephone wiring. Cat-5 cable is unshielded wire containing four pairs of 24-gauge twisted copper pairs, terminating in an RJ-45 jack. If a wire is certified as Cat-5 and not just a twisted pair wire, it will have "Cat-5" printed on the shielding.
How many pairs of wire does gigabit ethernet use on utp cable?
4 pairs of wires.

What is a cable that transmits and receive wire pairs in one of the connectors are reversed?
A crossover cable reverses the signals at ends of the cable.
What are the two factors used to determine the different category UTP cable?
To test whether a cable deserves to be called, for example, "category 5e", an alternating current ("signal") is injected at different frequencies on each pair of wires, and measurements are made, how much energy crosses over to other pairs of wire. The less energy crosses over, the better. The higher cable categories use the same methods, but they have more stringent requirements.To test whether a cable deserves to be called, for example, "category 5e", an alternating current ("signal") is injected at different frequencies on each pair of wires, and measurements are made, how much energy crosses over to other pairs of wire.

What technique is used to achieve 1-Gbps throughput over a CAT 5 cable?
CAT5 cable is actually not able to sustain 1Gbps transfer rates, as the two pairs that are used only for grounding in CAT5, and are used for signal in CAT6, are not controlled as tightly as is necessary for full throughput. A gigabit network, finding itself connected with CAT5 cable, will degrade itself to 300Mbps.
Why do UTP and STP have twists?
STP - Shielded Twisted Pair is twisted to reduces crosstalk. Crosstalk is when the signal crosses wire and reduces the communication quality. Twisting the pairs reduces the signal transmission to other wires in the cable "pack". Twisting them increases the length the cable can be run. Category 5 has a usable length of 100m, 330ft.
What is cat5 wiring?
CAT5 is an Ethernet cable standard defined by the Electronic Industries Association and Telecommunications Industry Association (commonly known as EIA/TIA). CAT5 is the 5th generation of twisted pair Ethernet cabling and the most popular of all twisted pair cables in use today. CAT5 cable contains four pairs of copper wire. CAT5 supports Fast (100 Mbps) Ethernet and comparable alternatives such as ATM. As with all other types of twisted pair EIA/TIA cabling, CAT5 cable runs are limited to a maximum recommended run rate of 100m (328 feet). Although CAT5 cable usually contains four pairs of copper wire, Fast Ethernet communications only utilize two pairs. A new specification for CAT5 cable, CAT5 enhanced (CAT5e), supports short-run Gigabit Ethernet (1000 Mbps) networking by utilizing all four wire pairs and is backward-compatible with ordinary CAT5. Twisted pair cable like CAT5 comes in two main varieties, solid and stranded. Solid CAT5 cable supports longer runs and works best in fixed wiring configurations like office buildings. Stranded CAT5 cable, on the other hand, is more pliable and better suited for shorter-distance, movable cabling such as on-the-fly "patch" cabling.
