Ethernet cables are divided into two categories: straight-through and crossover.
Straight-through cable: The sequences of the twisted pairs crimped in the RJ-45
connectors at both ends are the same. It connects a terminal device (PC or router)
to a HUB or LAN Switch.
Crossover cable: The sequences of the twisted pairs crimped in the RJ-45
connectors at both ends are different. It connects a terminal device (PC or router)
to another terminal device. You make crossover cables by yourself.
Note:
In making network cables, shielded cables are preferred for the sake of
electromagnetic compatibility.
