Huh... Yaah lot of discussion and i am doing lab for Twisted pair cable with RJ45(Registered Jack)

And Folder sharing in connected networks.

I am confidentially sharing a folder with the network but I got a little nervous and made a mistake in twisted pair cable crimping for arranging the wire to insert in the jack with order on both sides. Okey well…. All mistakes for learning new things.
