Study Notes
Data Communications System Concepts
- Medium: An example would be a network cable or wireless signal that transmits data between devices.
- Destination: The endpoint in a data communications system that receives the information sent from the source.
- Source: An example includes a computer or sensor that generates data to be communicated to another device.
- Interfaces: Serve as intermediaries allowing different systems to communicate, translating commands and signals between hardware and software.
- OSI Model - Physical Layer: Responsible for the actual transmission of raw data over a communication medium, dealing with hardware aspects like cables and signaling.
