Transmission Modes: Simplex, Half Duplex, Full Duplex

In this video, Abish Gupta from Technical Tech explains three types of data transmission modes: simplex, half duplex, and full duplex. Simplex allows data transmission in one direction only, exemplified by radios. Half duplex enables data transmission in both directions, but not simultaneously, as seen in walkie-talkies. Full duplex allows simultaneous data transmission in both directions, with mobile phones being a prime example.

What is the primary characteristic of simplex transmission?

• Data can only be sent in one direction.

• Data cannot be sent or received.

• Data can be sent and received simultaneously.

• Data can be sent in both directions but not at the same time.

Which of the following is an example of a simplex device?

• Walkie-talkie

• Mobile phone

• Radio

• Computer

What does half duplex transmission allow?

• Simultaneous sending and receiving of data.

• Sending data only in one direction.

• Neither sending nor receiving data.

• Sending and receiving data, but not at the same time.

Which device is a good example of half duplex transmission?

• Walkie-talkie

• Mobile phone

• Radio

• Television

What is the key feature of full duplex transmission?

• Data can be sent and received simultaneously.

• Data cannot be sent or received.

• Data can be sent in both directions but not at the same time.

• Data can only be sent in one direction.

Which of the following is an example of a full duplex device?

• Television

• Mobile phone

• Radio

• Walkie-talkie
