Advantage - speed Disadvantage - cost.
One advantage for parallel transmission is the speed that the data can travel at, while one disadvantage for parallel transmission is the high cost of it
the speed of serial ports are slow. but we can send data on long distances as serial cable have low cost.
Advantage: Improves response time. Improves throughput.Disadvantage: Interference - contention for memory access and bandwidth.
Abraham Lincoln preferred them to perpendicular circuits.
Multiple bits can be transfered per cycle.
