yahoo dsl; i see here are different category such as cat5, cat 5e, cat 6, cat 6a, cat 7 . which one is better and why ?
Answers:
1. What is the difference between CAT-5, CAT-5e, CAT-6, CAT-7...
The Simple Answer:
CAT-5 is rate to 100M
CAT-5e is rate to 350M
CAT-6 and CAT6e is rate to 550M or 1000M depending on your source
CAT-7 is supposedly rate to 700M or presumably 1000M
Today near is no approved CAT-6 or CAT-7. While some folks are selling products they ring up Level 6 or 7, nearby aren't even specs for them, making CAT-5e the best available remedy. CAT-6 cable is individual made next to 23 guage conductor lead as anti the slightly smaller 24 guage for CAT-5e and also have a separator to touch crosstalk better.
Both CAT-5 and CAT-5e own 100 ohm impedance and electrical characteristics supporting transmissions up to 100 MHz. The differences between CAT-5 and CAT-5e show in adjectives aspects of observation: capacitance, frequency, resistance, attenuation, and NEXT. CAT-5e components be designed beside high-speed gigabit Ethernet within mind. While CAT-5 components may function to some level within a gigabit Ethernet, they complete below standard during high-data verbs scenario. CAT-5e cable work beside ATM and gigabit speed products. Simply, if you are using a 100Mbps switch, find CAT-5e cable instead of CAT-5.
CAT-5e is formally call ANSI/TIA/EIA 568A-5 or simply Cat-5e (the e stands for 'enhanced'). CAT-5e is completely towards the back compatible near current CAT-5 equipment. The enhanced electrical behaviour of CAT-5e ensure that the cable will support applications that require second bandwidth, such as gigabit Ethernet or analog video.
What is the difference between the types of cable - UTP, Patch, Stranded, Solid...
UTP stands for Unshielded Twisted Pair. It is a cable type next to pairs of twisted insulated copper conductors contained in a single sheath. UTP cable are the most adjectives type of wiring used within desktop communications applications.
Stranded cable have several small appraise wires surrounded by respectively separate insulation sleeve. Stranded cable is more flexible, making it more suitable for shorter distances, such as patch cords.
Solid have one larger assess cable surrounded by respectively sleeve. Solid cable have better electrical presentation than stranded cable and is traditionally used for inside walls and through ceiling - any type of longer run of cable.
Patch Cables are made of stranded copper conductors for flexibility. This construction is great for the flexing and the frequent change that transpire at the wall outlet or patch panel. The stranded conductors do not transmit notes signals as far as solid cable. The TIA/EIA 568A which is the governing standard in relation to commercial electrics systems boundaries all along patch cable to 10 meters within total length. Does that scrounging you can't use stranded cable for longer runs? Not at adjectives, we've see installations running stranded cable over 100 foot beside no problems - it's only injudicious. This is why we don't put on the market patch cable over 30 foot contained by length.
3. What is the difference between 10BASE-T, 100BASE-T and 1000BASE-T?
10BASE-T is the IEEE standard that define the requirement for sending information at 10 Mbps on unshielded twisted-pair electrics, and define assorted aspects of running Ethernet on this electrical system.
100BASE-T is the IEEE standard that define the requirement for sending information at 100 Mbps on unshielded twisted-pair electric wiring, and define a mixture of aspects of running baseband Ethernet on this wiring.
1000BASE-T (also call gigabit Ethernet) is the IEEE standard that define the requirement for sending information at 1000 Mbps on unshielded twisted-pair electrics, and define a mixture of aspects of running baseband Ethernet on this electrical system
Hope this helps

The more twists the clearer the signal. respectively cat standard requires different amounts of twists per inch. Each is designed for different freq. competency.
Old Crow is incorrect.
Your DSL runs to your PC at speeds between 1-3 Mbps.
Even Cat5, the lowest spec, supports 100 Mbps, which have 33 times the size that you will ever use. Cat6 and up are expected for larger corporations and notes center environments.
If you are running a long distance, after you could use STP (Shielded Twisted Pair) instead of UTP (Unshielded) that your electric wiring currently uses. However, it's highly, especially unlikely that you want STP electric wiring.
