CAT-5 Cross Over pin configuration

The TIA/EIA 568B straight through cable consists of four pairs of twisted pair lines. These ethernet cables can be shielded twisted pairs (STP); screened twisted pairs (ScTP); or most commonly, unshielded twisted pairs (UTP). The twisted pairs serve to cancel out the any RF/EM (radio-frequency/electromagnetic) noise through the lines.
