The configuration described in the question is that the colored wires at one end of the cable are in reverse sequence to the colored wires at the other end of the cable. This type of cable is used for connecting networking devices with different functionalities, such as connecting a computer to a router or a switch to a hub.
The four types of cables commonly used in networking are rolled, crossover, coaxial, and straight-through.
A rolled cable is also known as a console cable and is used to connect a computer to a networking device's console port. The rolled cable has the same sequence of colored wires at both ends of the cable.
A crossover cable is used to connect two networking devices of the same type, such as two computers or two switches. The crossover cable has the colored wires at one end of the cable in reverse sequence to the colored wires at the other end of the cable, which allows the two devices to communicate with each other.
A coaxial cable is a type of cable that has a copper conductor at the center, surrounded by a layer of insulation, a braided shield, and an outer jacket. Coaxial cables are used for cable TV, broadband internet, and other applications that require high-bandwidth data transmission.
A straight-through cable is used to connect two networking devices of different types, such as a computer and a switch or a router and a hub. The straight-through cable has the same sequence of colored wires at both ends of the cable.
Therefore, the configuration described in the question is that of a crossover cable, where the colored wires at one end of the cable are in reverse sequence to the colored wires at the other end of the cable.
