What technique is used with UTP cable to help protect against signal interference from crosstalk?

Unshielded Twisted Pair (UTP) cables use the technique of twisting pairs of wires together to help reduce crosstalk and signal interference. The twisting of the wires helps to cancel out electromagnetic interference (EMI) by ensuring that any noise induced on one wire of the pair is also induced on the other, thereby minimizing the net effect. Additionally, the tighter the twist, the better the protection against crosstalk, making this technique effective for maintaining signal integrity in networking applications.
