It is often said that crossover cables 'reverse the transmit and receive signals' compared to straight through cables. However I am yet to see an actual explanation of why the reversal of signals is required, and the effect that it has. Thus, I pose to readers the following questions:
What is the purpose of reversing the transmit and receive signals?
It is said it this post - https://www.itprc.com/difference-straight-through-cross-over-rollover-cables/ - that the criss-crossing of the wires allows for two devices to communicate simultaneously. How is this so?
Is it technically correct to say that the signals are reversed? It seems to me that, based on the graphic below, the signals are reversed (compared to straight through wiring) on one side of the cable, but remain in the same position on the opposite side:
Please keep technical jargon to a minimum; if possible. I am not a professional in this area, just trying to gain a conceptual understanding of how this form of cabling works. Thanks!
