Higher data transfer rates
Uses fewer wires, simplifying cabling and reducing cost
More resistant to electrical interference
Transmits data simultaneously in both directions
Explanation
Serial transmission utilizes fewer wires, making cabling simpler and more cost-effective, especially over long distances.
