What is Crossover Cable and Straight Through Cable

Crossover Cable is simply related to the connection of two devices of the same technology or systems like DCE-DCE or DTE-DTE, basically connecting asymmetrical devices like DTE-DCE cables are known as cross-link cables. IBM (International Business Machines Corporation) introduced such a distinction of all the devices.
In contrast, straight-through cables connect complimentary system devices by using direct wiring e.g. a computer to a switch plug but the crossing of cables in an adapter connection allows:

• Connecting two or more routers or switches to work as one wider device.
• Connecting the output of one device to the input of the other device.
• Allowing two DTE devices to communicate without an interlinking cable or hub know e.g. PCs.

Straight through cables worked on most of the devices or applications, but crossover cable is also used sometimes. In straight-through, both pins of one and another end are matched like pin 1 or pin 1, Pin 2 or pin 2, etc. In straight-through cables, a particular color cable attached to a pin number at both ends yet.

In crossover cables, all pins are not similar, all the transmitters are exchanged at the terminations. For example, if pin A on the first end goes to pin B on the other, then pin B on the first-hand goes to pin A on the other. Such cables of the crossover are electrically consistent, which means they can run identically nevertheless of which way you plug them in. In crossover cables, a particular color cable connects to one pin at one end and a different pin at the other.
