Study Notes
Network Fundamentals
- A network is a set of devices (nodes) connected by communication links, capable of sending and/or receiving data generated by other nodes on the network.
Data Communication System
- The effectiveness of a data communication system depends on three fundamental characteristics: delivery, accuracy, and timeliness.
- The components of a data communication system include:
- Device (sender and receiver)
- Transmission medium (communication links)
- Protocol
- Message (data)
Protocol
- A protocol is a set of rules and procedures that govern data communication over a network.
- A protocol defines the format, timing, and error-checking systems used in data communication.
- The main purpose of a protocol is to coordinate the transfer of data between sender and receiver.
Network Applications
- Examples of network applications include:
- Real-time discussions over the internet (e.g., chat rooms)
- File transfer
- A network application that is NOT an example is: calculator program
Data Transmission
- The transmission medium is responsible for transmitting the message (data) in a data communication system.
- Accuracy is an essential fundamental characteristic for the effectiveness of a data communications system, ensuring that data is received accurately.
