Study Notes
Data Communications
- Data communications involve the exchange of data between two devices via a transmission medium, such as a wire cable.
- The components of data communication include:
- Message: The information being exchanged
- Sender: The device sending the message
- Receiver: The device receiving the message
- Transmission medium: The physical path used for data transfer
- Protocol: A set of rules governing how the data is transmitted
Computer Networking
- Refers to interconnected computing devices that can exchange data and share resources with each other.
- These networks use communications protocols to transmit information over physical or wireless technologies.
Computer Network Classifications
- Categorized by size:
- LAN (Local Area Network): Connects devices within a limited geographical area, like a building or home
- PAN (Personal Area Network): Connects devices within a close proximity of a single person, such as a Bluetooth connection
- MAN (Metropolitan Area Network): Connects devices across a larger geographical area, like a city
- WAN (Wide Area Network): Connects devices over a very wide geographical area, typically spanning countries or continents, utilizing satellite or fiber optic cables for long-distance connections.
