Question

What is simplex, half duplex, and full duplex?

Answer 1

These terms refer to the way data is transmitted between two devices in a communication system. Here's a simple breakdown:

1. Simplex

1. One-way communication: Data flows in only one direction.
   

1. Example: A keyboard to a computer. The keyboard sends data to the computer, but the computer doesn’t send data back to the keyboard.
   

2. Half-Duplex

1. Two-way communication, but not at the same time: Data can flow in both directions, but only one direction at a time.
   

1. Example: Walkie-talkies. When one person speaks, the other must listen. They can't talk and listen at the same time.
   

3. Full-Duplex

1. Two-way communication at the same time: Data can flow in both directions simultaneously.
   

1. Example: A phone call. Both people can talk and listen at the same time without having to wait.
   

In summary:

1. Simplex: One-way communication.
   

1. Half-Duplex: Two-way communication, but not simultaneously.
   

1. Full-Duplex: Two-way communication, simultaneously.
