Cost | Economical | Expensive |
Bits transferred at 1 clock pulse | 1 bit | 8 bits or 1 byte |
Speed | Slow | Fast |
Applications | Used for long-distance communication. E.g., Computer to computer | Short distance. E.g., computer to a printer |
Number of communication channel required | Only one | N number of communication channels are needed |
