A serial bus is a type of architecture that allows for the transfer of data one bit at a time through a single wire or fiber. This method is used on a variety of devices, including Ethernet connections. In contrast, a parallel bus uses multiple wires to connect the CPU’s I/O port to peripherals.
Serial Bus vs. Serial Port
While they sound similar, a serial bus and a serial port serve vastly different functions. While both employ serial communication, a serial bus allows for the connection of multiple devices, while a serial port connects a computer to just one device.
What are some examples of serial buses?
In addition to Ethernet connections, other examples of serial buses include USB, SATA, and FireWire.
Why are some devices designed to use a serial bus?
Serial buses are often used when designers want to connect multiple devices to a single input/output port but do not want to use a parallel bus that requires multiple wires to connect the devices.
Overall, a serial bus is an essential part of many modern devices, making it possible for multiple devices to connect to a single input/output port with ease.
