I believe zero about conductors being directional, but in the case of shielded cables you want the shield connected at the source but not the destination, which is the reason for the arrows. In most systems though shielding is barely necessary so this may not even matter.
Dumbest cable question
I know some cables may be directional or at least have some type of arrow showing where to connect each end. However, most do not. Here you go:
Is there any value to rotate your cables every now and then. In other words, switch the source component end with the “end” end. This way signals have a chance to flow opposite direction within the cable
If this is a super silly question, my apologies.
