10baseT & 100baseTX

Is this true?
100 baseTx uses 2 pair of twisted wires, but actually has 8 single wires total?

How many wires does 10baseT use?

Thanks ums!

Actually, it does mention it for 10baseT:

100BaseTX (Fast Ethernet, 802.3u)

Is similar to 10BaseT, except it requires Category 5 UTP or Category 1 STP (Shielded Twisted Pair) cabling. Only uses 4 of the 8 wires like just like 10BaseT. The maximum data transfer rate is 100 Mb/s and the encoding type is 4B/5B coding.

4 wires = 2 pairs

Pretty much all of the 10/100 mbps ethernet standards use 2 pairs of wires. The only exception I can think of is 10Base4, which uses 4 pairs (8 wires total). I don't think 10Base4 is used much, if at all.
