In parallel communications, bits can be transmitted in parallel over multiple wires which make it theoretically eight times faster than a serial connection. However, there are some issues with this type of connection. Which of the following are issues with a parallel communication? (Choose two)
Crosstalk
Split Horizon
Network congestion
Clock skew
Unsecured data
Bits can be transmitted in parallel over multiple wires in Parallel communication which makes it faster than a serial connection. However, there are issues with this type of communication. One is Clock Skew where some packets across the various wires do not arrive at the same time, creating synchronization issues. Another issue is Crosstalk (caused by electromagnetic interference, along a circuit or a wiring pair), especially as the wire length increases.
