L2 ICT U1 Transmission Modes Quiz

What are the three different transmission modes in terms of the flow of data?

• Simplex, Duplex, Triplex

• Unidirectional, Bidirectional, Multidirectional

• Simplex, Half-duplex, Full-duplex

• Serial, Parallel, Cross-linked

In simplex transmission mode, how is data sent between devices?

• In both directions simultaneously

• Only in one direction, from the transmitter to the receiver

• In multiple directions, depending on the network

• In two directions, but not simultaneously

Which of the following devices typically uses simplex transmission mode?

• Printers

• Smartphones

• Remote Controllers

• Computers

What is half-duplex transmission?

• Data can be sent in both directions simultaneously.

• Data can be sent in one direction over a single wire or channel.

• Data can be sent in both directions but only one at a time.

• Data can be sent in both directions and devices can send and receive data at the same time.

Which of the following devices typically uses half-duplex transmission?

• Telephones

• Computers

• Printers

• Smartphones

What is full-duplex transmission?

• Data can be sent in one direction over a single wire or channel.

• Data can be sent in both directions but only one at a time.

• Data can be sent in both directions and devices can send and receive data at the same time.

• Data can be sent in both directions simultaneously but using different channels.

Which of the following devices typically uses full-duplex transmission?

• Walkie-Talkies

• Printers

• Telephones

• Keyboards

What is the main difference between serial and parallel transmission?

• Serial transmission can send data over larger distances, while parallel transmission cannot.

• Parallel transmission sends bits of data one at a time over a single wire, while serial transmission sends multiple bits simultaneously.

• Serial transmission sends bits of data one at a time over a single wire, while parallel transmission sends multiple bits simultaneously.

• Parallel transmission is more commonly used nowadays compared to serial transmission.

Which transmission method is more commonly used today due to its overall advantages?

• Parallel transmission

• Serial transmission

• Half-duplex transmission

• Full-duplex transmission

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

• Parallel transmission can send data over longer distances.

• Parallel transmission is less expensive than serial transmission.

• Parallel transmission is slower than serial transmission.

• Parallel transmission can send more data at one time because it uses multiple wires or channels.
