Hello, I want to ask a question that is confusing me.
The UTP cable is designed of 8 little cables, 2 for transmit and 2 for recieve.
If 2 for transmit and 2 for recieve and they are independant of each other, then why there will be a collision if the two devices sends at the same time????
The second question is that what is the purpose of the other 4 little cables.
