 Difference between 10Base-T/100Base-TX/1000Base-T

What is the difference between 10Base-T/100Base-TX/1000Base-T standards and what advantages does one have over another? I would appreciate it if you could get back to me in a timely manner.

Dear Ben,

This question is more about active equipment, not cabling (the specialty of this helpdesk). However, couple pointers I can give you are: the most obvious difference is speed. 1000MB/s is obviously 100 times the speed of 10. This is not a precise ratio because some of the data transferred is used for internal purposes, but the rough ratio is going to be about this much. Then there is a difference in how many pairs of conductions the applications use: 10BASE-T and 100BASE-TX use only two pairs out of four available in a category cable whereas 1000BASE-T uses all four pairs.
There are obviously differences in price, acceptance etc. So, you'd have to specify exactly what kind of difference you're most interested in.

Dmitri Abaimov, RCDD
