the end of the cable (usually category 5 or category 5E cable).
Figure 19 RJ-45 connector
The following describes two common types of cables and how to make them.
• Straight-through cable: The colored wires are of the same sequence at the two ends of the cable. A
straight-through cable is usually used to connect these devices: PC to hub or switch, router to hub or
switch.
• Crossover cable: The colored wires are of different sequences at the two ends of the cable. A
crossover cable is usually used to connect these devices: PC to PC, router to router, or PC to router.
