Explain the following as used in communication. Simplex Half duplex Full duplex

Simplex:

- Communication flow is unidirectional, meaning data can only travel in one direction.
- Example: Radio broadcasting, where a transmitter sends signals to multiple receivers.

Half Duplex:

- Communication flow is bidirectional, but only one device can transmit at a time.
- Example: Walkie-talkies, where users need to take turns speaking.

Full Duplex:

- Communication flow is bidirectional, and both devices can transmit and receive simultaneously.
- Example: Telephone calls, where both callers can speak and hear each other at the same time.

Comparison:

| Feature | Simplex | Half Duplex | Full Duplex |
|---|---|---|---|
| Communication Flow | Unidirectional | Bidirectional (one at a time) | Bidirectional (simultaneous) |
| Example | Radio broadcasting | Walkie-talkies | Telephone calls |
| Applications | One-way communication, broadcasting, paging | Two-way communication with limited interactivity | Real-time, simultaneous communication |
