Why do we need crossover cables?
Moreover, nothing will be sent on RX wire. Therefore, neither computer will be able to receive anything. At this point, the crossover cable is needed to make connections between two PCs. Since this kind of cable is crossed, the signal sent on TX wire from PC 1 can be received on the RX wire of PC 2. This is the reason why the crossover cables are often used to connect two same devices.
What type of cable is used for direct computer to computer connections?
Some networking applications require an Ethernet crossover cable, which has a T-568A connector on one end and a T-568B connector on the other. This type of cable is typically used for direct computer-to-computer connections. The following section will introduce the straight through cable (or patch cable) and crossover cable in details.
What Is a Patch Cable?
Many networking professionals use the term patch cable to refer to any kind of straight through cable. So a patch cable is often called a straight through cable. In other words, patch cable does not change or swap along its way. Both ends use the same wiring standard: T-568A or T-568B. So both side (connector A and connector B) of patch cable have wire arrangement with same patch cable colors (as shown in the following picture). Specifically, Pin 1 on connector A goes to Pin 1 on connector B, Pin 2 to Pin 2, etc. These patch cables are widely used for connecting the computer to the switches, hubs, or routers.
What happens if a switch is mixed between two computers?
What happens if a switch is mixed between two computers? In fact, switch is designed to communicate in between two computers, which has an innate crossing of the wires. Therefore, we do not need the cable to cross for us. What the PC 1 sends on its TX wire is received by the switch on its RX wire, and then transmits on its TX wire, finally is received by the other PC's RX wire. And vice versa. Therefore, when a switch is connected to a PC, it can simply use a patch cable.
What happens if you have two switches in the mix?
What then happens if we have two switches in the mix? Two switches separately cross the wire once, therefore another pair crossing in between the switches is emerges. As mentioned above, two same devices need a cross cable to make a connection. From the diagram above, we can see:
