Study Notes
Characteristics of Data Communication
- Essential characteristics include transmission medium, signal representation, and encoding methods.
- Not a characteristic is processing speed, which pertains to hardware capabilities rather than communication itself.
Components of Data Communication
- Sender: Originator of the message, which can be a person or a device.
- Message: Information conveyed, composed of data in a form suitable for transmission.
- Transmission Medium: Physical path (wired or wireless) that carries the message from sender to receiver.
- Receiver: The device or person that receives and decodes the message.
- Protocol: Set of rules governing the format and transfer of data.
Categories of Computer Networks
- Common categories include Local Area Network (LAN), Wide Area Network (WAN), and Metropolitan Area Network (MAN).
- Not a category is personal area network (PAN), typically considered a subset within the broader categories.
Elements of a Protocol
- Syntax: The structure of the data, including how the messages are formatted.
- Semantics: Meaning of the message and information conveyed.
- Timing: Control of when data is sent and received; includes speed and synchronization.
- Error Control: Mechanisms for detecting and correcting errors that occur during transmission.
Purpose of Standards in Networking
- Ensure compatibility and interoperability among devices and systems from different manufacturers.
- Promote reliability and efficiency in data transmission and network operation.
- Facilitate the evolution of technology by establishing guidelines and best practices.
