What is the main difference between a yellow and blue Ethernet cord?

The main difference between a yellow and blue Ethernet cord lies in their intended use and the type of Ethernet connection they support. Yellow Ethernet cords are typically used for crossover connections, which are used to connect two devices of the same type, such as two computers or two switches. On the other hand, blue Ethernet cords are used for straight-through connections, which are used to connect devices of different types, such as a computer to a switch or a router.

In terms of technical specifications, the difference between yellow and blue Ethernet cords is the way the wires are arranged inside the cable. Yellow Ethernet cords have a crossover wiring pattern, where the transmit and receive wires are swapped, allowing devices to communicate with each other directly. Blue Ethernet cords, on the other hand, have a straight-through wiring pattern, where the transmit and receive wires are not swapped, allowing devices to communicate with each other through a switch or router. This difference in wiring pattern is what determines the intended use of each type of Ethernet cord.

Are yellow and blue Ethernet cords interchangeable?

While yellow and blue Ethernet cords may look similar, they are not entirely interchangeable. Using a yellow Ethernet cord for a straight-through connection or a blue Ethernet cord for a crossover connection can result in a failed connection or poor network performance.
