What is the main difference between parallel and serial communication?
What is the main difference between parallel and serial communication?
- Parallel communication transfers data one bit at a time, while serial communication transmits data on all the wires simultaneously.
- Parallel communication uses a single wire, while serial communication uses multiple wires running parallel to each other.
- Parallel communication transmits data on all the wires simultaneously, while serial communication transmits data one bit at a time.
- Parallel communication uses multiple wires running parallel to each other, while serial communication uses a single wire to transfer data one bit at a time. (correct)
What effect can clock skew have on parallel data transfer speed?
What effect can clock skew have on parallel data transfer speed?
- Clock skew increases the speed of every link in parallel data transfer.
- Clock skew reduces the speed of every link to the slowest of all of the links in parallel data transfer. (correct)
- Clock skew has no effect on parallel data transfer speed.
- Clock skew balances the speed of every link in parallel data transfer.
What can lead to inter-symbol interference and noise in parallel communication?
What can lead to inter-symbol interference and noise in parallel communication?
- High transmission rates in parallel communication.
- Equal propagation times in parallel communication.
- Crosstalk between the parallel lines in parallel communication. (correct)
- Capacitance and mutual inductance between the wires of a serial system.
