An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly. It is most often used to connect two devices of the same type: e.g. two computers (via network interface controller) or two switches to each other.
Accordingly, why straight through cables are used?
Straight-Through wired cables are most commonly used to connect a host to client. When we talk about cat5e patch cables, the Straight-Through wired cat5e patch cable is used to connect computers, printers and other network client devices to the router switch or hub (the host device in this instance).
What is cross cable and straight cable?
An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. By contrast, patch cables or straight through cables are used to connect devices of different types, such as a computer to a network switch or Ethernet hub.
What is the difference between a cross over and straight through cable?
Straight-through Ethernet cables are the most commonly used. Crossover cables use two different wiring standards: one end uses the T568A wiring standard, and the other end uses the T568B wiring standard. For example, a computer with Auto MDI-X can use either a straight-through or crossover cable for any application.
