Study Notes
Communication Modes
- Simplex mode is a characteristic of one-way communication, where data flows only in one direction.
- Half-duplex mode allows data flow in both directions but not at the same time.
- Full-duplex mode is characterized by simultaneous data flow in both directions.
Real-World Examples
- A walkie-talkie is a good example of half-duplex mode, where one person speaks at a time.
Network Protocols
- The main purpose of a network protocol is to manage and facilitate communication between devices on a network.
Data Sequencing
- Data sequencing is a function that assigns a sequence number to each packet of data, ensuring that packets are reassembled in the correct order at the receiving end.
