Common Modes of Transmission Quiz

Which of the following is NOT a common mode of transmission?

• Simplex

• Half-duplex

• Full-duplex

• Double-duplex

What does simplex transmission refer to?

• Sending data in multiple directions simultaneously

• Sending data in two directions, but not simultaneously

• Sending data in one direction only

• Sending no data at all

What is a characteristic of half-duplex transmission systems?

• Devices can transmit and receive data at the same time.

• Devices can only receive data but not transmit.

• Devices can transmit data but cannot receive at the same time.

• Devices do not transmit and receive data at the same time.

In what scenario can half-duplex transmissions be used?

• For full continuous two-way communication.

• For monitoring and controlling manufacturing processes.

• For systems that require simultaneous transmission and reception.

• For high-speed internet connections.

What does a full-duplex system allow?

• One-way communication at different times

• Two-way communication at different times

• Two-way communication at the same time

• One-way communication at the same time

Which of the following is an example of a full-duplex system?

• A walkie-talkie

• A megaphone

• A land or mobile telephone system

• A public address system

How are bits of data transmitted in parallel transmission?

• Sequentially over a single wire

• Simultaneously over an equal amount of bits together

• In a compressed format to save space

• Over a wireless network

What is the maximum range of parallel transmission?

• 50 meters

• 5 kilometers

• 5 meters

• 500 meters

Why is parallel transmission rarely used these days in computing?

• Because it is too fast

• Because it is too reliable

• Because of its costs and limited range

• Because it is not compatible with modern devices

For what purpose was parallel transmission once popular?

• Connecting mobile phones to computers

• Connecting printers to computers

• Connecting computers to the internet

• Connecting external hard drives to computers
