Serial and Parallel Data Transmission

What is serial transmission?

• Data sent randomly

• Data sent in a loop

• Data sent multiple bits at a time

• Data sent one bit at a time

What is parallel transmission?

• Data sent multiple bits at a time

• Data sent one bit at a time

• Data sent in a loop

• Data sent randomly

Which transmission method requires multiple channels?

• Parallel transmission

• Serial transmission

• Loop transmission

• Random transmission

What is the main advantage of parallel transmission over serial transmission?

• Faster data transfer rate

• Less space required

• Less expensive

• Less technical issues

What is crosstalk in parallel transmission?

• Interference between close electrical wires

• Data sent one bit at a time

• Data sent randomly

• Data sent in a loop

Why is skew a problem in parallel transmission?

• Causes data corruption

• Improves data accuracy

• Increases data transfer speed

• Reduces cost

Which type of cables do not suffer from crosstalk?

• Coaxial cables

• Fiber optic cables

• Twisted pair cables

• Electrical cables

What is the trend in replacing parallel buses with serial buses?

• Using both in equal measure

• Replacing with serial buses

• No trend observed

• Increasing parallel buses

Which type of communication method is commonly used for medium to long-range transfers?
