Data Flow
Data flow refers to the direction in which the data travels between devices in a network
It is categorized in three primary types:
Types of Data Flow
- Simplex
- Definition: In simplex mode, data travels in only one direction, from the sender to the receiver.
- Use Cases: Common in devices like keyboards and monitors, where the data doesn’t need to return.
- Example: Radio and TV broadcasting, where information flows from the station to the receiver with no return signal.
- Half-Duplex
- Definition: Data flows in both directions, but not simultaneously. Only one device can send or receive at any given time.
- Use Cases: Useful in situations where data exchange is intermittent.
- Example: Walkie-talkies, where one person speaks at a time, and the other listens.
- Full-Duplex
- Definition: Data flows in both directions simultaneously, allowing both devices to send and receive at the same time.
- Use Cases: Essential for real-time communication and high-speed networks.
- Example: Telephone networks, where both people can talk and listen simultaneously.
