Data Transmission Quiz

What is the main characteristic of serial data transmission?

• Transmits multiple bits at a time

• Uses multiple wires for transmission

• Transmits one bit at a time

• Transmits data at a very high speed

Which of the following is an example of serial data transmission?

• Sending data to a printer

• Sending data from a computer to a modem over a telephone line

• Transmitting data to a monitor

• Transmitting data to a hard drive

Why is serial data transmission slower than parallel data transmission?

• It transmits one bit at a time

• It transmits multiple bits at a time

• It uses more cables

• It is less reliable

What is the main characteristic of parallel data transmission?
