What do the arrows mean on my cable?

I'm sure I am not the FIRST one to mention this, but in case, Many manufacturers have discovered that the alignment in the copper atoms lines up in a way that makes them directional, Directional in how they transfer a signal the best, SO they actually mark the cables as to what direction they will operate at optimum levels.

Like I said @jjss49 Who cares. Pot meet kettle you did what you accused the OP of, trolling.

@roxy54 gfys. 

Do not care if you two were here when Al Gore invented the internet. You two are no better than the people you cast dispersions on. 

Go ahead get this post deleted ladies. 

@juanmanuelfangioii

You two are no better than the people you cast dispersions on.

we truly don’t believe we are better than others, in fact we come here to learn and help other real users

but i suspect we are indeed better than you, in that we don’t hide behind the keyboard and play anonymous tough guy... no courage required for that... just lame

Thanks @jjss49. I couldn't have said it better. 

And by the way Juan, its aspersions, not dispersions. 

@roxy54 LOL just can’t help yourself.

@jjss49 you were being a Richard to the OP. Belittling his post and called him a troll. And I am an ass for pointing out how big an ass you were to him. After he posted his explanation addressing your accusations, you are yet to admit you’re wrong. So you are here to learn and I presume teach and you only contributed by calling out the OP. 

Class. 

Have a great day you Agon Karen’s.
