One person has suggested: "Its a very small amout of voltage. Usually microvolts." This is somewhat inaccurate, but only by a factor of around 1,000,000 times too small. A more accurate number is: "around 2.5 volts peak differential". Your typical consumer LAN uses 10Base-T signalling over a Category 3, 4 or 5 twisted-pair cable. The 10BASE-T transmitter output voltage specified in the standard (IEEE 802.3-2005 14.3.1.2.1) requires a peak differential voltage of 2.2 to 2.8 V into a 100-Ohm resistive load. There are IEEE technical discussions (March 2007) about reducing it to below 2 volts, perhaps using a "negotiation" protocol for devices on the LAN to choose a lower voltage if they are capable.
Telephone is Cat3 while the cable coming form the modem is Cat5
Cat5 cable
a paki
Cat5 is the standard.
cat5
Twisted pair cables were invented by Alexander Graham Bell, but the name of the creator of the Cat5 twisted pair cable is unknown.
They are the same.
One can buy an HDMI over Cat5 cable on various places across the world wide web. The best place to buy a Cat5 is eBay, the best online store in the world.
Yes. cat6 is low voltage / signal wire.
100Base-T network require usually cat5 maximum of cable length 100 meters to 380meters.
It depends on brand and how much you buy. Usually a box of good cable is approx 25 cents a foot for 1000 feet
Cat5, Cat5e, Cat6, and Cat6e can be used, u can always use a better cable than required, but not the other way around
