Data Communication System Components
- A data communication system consists of devices, channels, message, and protocol.
Line Configurations
- Point-to-point connection: One device connected to another device.
- Multipoint connection: One device connected to more than two devices.
- Point-to-multipoint connection: One device connected to multiple devices.
Transmission Types
- Simplex transmission: One entity sends, the other receives.
- Half-duplex transmission: Both entities send and receive, but not at the same time.
- Full-duplex transmission: Both entities send and receive at the same time.
Star Network
- The number of cables in a star network is given by the formula: N(N-1)/2, where N is the number of devices.
Protocol
- A protocol defines the rules, structures, and timings of data exchange.
