Data Transmission (Group 1)

Which of the following best describes the half-duplex data transmission method?

• Data is transmitted over several wires

• Data is transmitted in both directions simultaneously.

• Data is transmitted in both directions, but one direction at a time.

• Data is transmitted in one direction only.

Benefits of USB (pick all that apply)

• Easy use

• Backwards incompatibility

• Can only be used in some devices

• Are prone to magnetic interference

In the packet switching process, data is broken down into:

• “Overviews”

• “Hops”

• “Packets”

• “Files”

Which part of the data packet structure contains an end of the data packet marker and the error detection method used?

• Header

• Payload

• Trailer

• Body

Can simplex transmission send data, from both the sending and receiving?

• Yes

• No

Data transfer interface can be:

• Parallel and Serial

• Simplex

• Half-Duplex and Full-Duplex

• Simplex, Half-Duplex and Full-Duplex

Parallel transmission is best used for:

• Long distance communication

• Short distance communication

In a serial simplex transmission, which describes it best:

• Data is transmitted in one direction, one bit at a time, down a single wire

• Data is transmitted in both directions, down multiple wire

• Data is transmitted in one direction, multiple bits at a time, down multiple wires

• Data is transmitted in both directions, down a single wire

True or False? Parallel data transmission works well over short distances?

• True

• False
