Final answer:
In a straight-through, the transmit and receive signal pairs are aligned by connecting the transmit signal of one device to the receive signal of the other device. This ensures proper data communication between devices.
Step-by-step explanation:
In a straight-through, the transmit and receive signal pairs are aligned in a way that ensures proper communication between devices. This alignment is achieved by connecting the transmit signal of one device to the receive signal of the other device. By doing so, the data sent by one device is received by the other device in a coordinated manner.
For example, in Ethernet communication, a straight-through cable is used to connect devices of different types, such as a computer to a switch. In this case, the transmit signal pin of the computer's network interface is connected to the receive signal pin of the switch's network interface, and vice versa. This alignment allows the computer to transmit data to the switch, and the switch to receive data from the computer.
Overall, the alignment of transmit and receive signal pairs in a straight-through configuration ensures proper data communication between devices.
