wenever a signal transmits in a cable,itself produces interference.this interfernce can damage the signal.using a twisted pair..we use two pairs of cable.

where in the single pair is tightly coupled so the interference get we use twisted pair..simpeeel...

becuase of elecromagnetic radiation effect we can twist the

Twisted pair cable one just twist the wire in order to get
the climping of RJ45 jack in a proper way to climp wires in
RJ45 jack in a sequence manner for communication between 2
similar devices we require cross cabling and for
communication between 2 dissimilar devices one requires
straight cabling.The sequence of straight cabling is
ue,whiteofblue and this is purely techinical solution.
