what does 10baseT means?

In twisted pair cable we usually use symbols like 10baseT 100baseT and so on.What does 10 and 100 means here?As much as i know it means frequency,but frequency should be mentioned as largest frequency and lowest frequency the cable can bear.Please guide me what it is.

10BASE-T - one of several physical media specified in the IEEE 802.3 standard for Ethernet local area networks (LANs), is ordinary telephone twisted pair wire. 10BASE-T supports Ethernet's 10 Mbps transmission speed. In addition to 10BASE-T, 10 megabit Ethernet can be implemented with these media types:

* 10BASE-2 (Thinwire coaxial cable with a maximum segment length of 185 meters)
* 10BASE-5 (Thickwire coaxial cable with a maximum segment length of 500 meters)
* 10BASE-F (optical fiber cable)
* 10BASE-36 (broadband coaxial cable carrying multiple baseband channels for a maximum length of 3,600 meters)

This designation is an Institute of Electrical and Electronics Engineers (IEEE) shorthand identifier. The "10" in the media type designation refers to the transmission speed of 10 Mbps. The "BASE" refers to baseband signalling, which means that only Ethernet signals are carried on the medium. The "T" represents twisted-pair; the "F" represents fiber optic cable; and the "2", "5", and "36" refer to the coaxial cable segment length (the 185 meter length has been rounded up to "2" for 200).

100BaseT - In 100 Mbps (megabits per second) Ethernet (known as Fast Ethernet), there are three types of physical wiring that can carry signals:

* 100BASE-T4 (four pairs of telephone twisted pair wire)
* 100BASE-TX (two pairs of data grade twisted-pair wire)
* 100BASE-FX (a two-strand optical fiber cable)

This designation is an Institute of Electrical and Electronics Engineers shorthand identifier. The "100" in the media type designation refers to the transmission speed of 100 Mbps. The "BASE" refers to baseband signalling, which means that only Ethernet signals are carried on the medium. The "T4," "TX," and "FX" refer to the physical medium that carries the signal. (Through repeaters, media segments of different physical types can be used in the same system.)

The TX and FX types together are sometimes referred to as "100BASE-X." (The designation for "100BASE-T" is also sometimes seen as "100BaseT.")

Thanks a lot .Got more knowlege than thought

>1st 10 mean 10Mbps,,,,,,base mean baseband,,,,,,,,,last T mean twisted pair
DataRate of wire,,,,,,,,,Type of transmission,,,,,,,,Type of wire

Extra:
Baseband:

1)Uses digital signalling

2)No frequency-division multiplexing

3)Bi-directional transmission

4)Signal travels over short distances

Broadband:

1)Uses analog signalling

2)Unidirectional transmission

3)Frequency-division multiplexing is possible

4)Signal can travel over long distances before being attenuated
