L2 ICT U1 Transmission Modes Flashcard

Front

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

Back

Simplex, Half-duplex, Full-duplex

Front

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

Only in one direction, from the transmitter to the receiver

Front

Which device typically uses simplex transmission mode? Options: Printers, Smartphones, Remote Controllers, Computers

Back

Remote Controllers

Front

What is half-duplex transmission?

Back

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

Front

Which of the following devices typically uses half-duplex transmission? Telephones, Computers, Printers, Smartphones

Back

Printers

Front

What is full-duplex transmission?

Back

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

Front

Which of the following devices typically uses full-duplex transmission? Walkie-Talkies, Printers, Telephones, Keyboards

Front

What is the main difference between serial and parallel transmission?

Back

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

Front

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

Back

Serial transmission

Front

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

Back

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