Question

Serial communication can be sped up by __________

(a) Using silver or gold conductors instead of copper

(b) Using high-speed clock signals

(c) Adjusting the duty cycle of the binary information

(d) Using silver or gold conductors instead of copper and high-speed clock signals

I got this question in exam.

This key question is from Fast Adder & Serial Adder in division Arithmetic Circuits of Digital Circuits

Answer 1

Right answer is (b) Using high-speed clock signals

The best explanation: For any serial data transmission there is required of continuously data supply and if the input supply (i.e. high speed clock signals) in a high amount the speed of serial communication can be increased. In serial communication, data is transmitted bit by bit. So the use of high speed clock pulses would make the process faster.
