Study Notes
Network Media Types
- Three primary types of network media: twisted-pair cable, coaxial cable, and fiber-optic cable.
Data Transmission in Fiber-Optic Cable
- Data is transmitted through fiber-optic cable using light impulses that travel along glass or plastic fibers.
Twisted-Pair Cable
- Twisting pairs in twisted-pair cable reduces electromagnetic interference and crosstalk between pairs.
Twisting Wires in Electrical Circuits
- Twisting wires creates magnetic fields that cancel each other out, enhancing signal integrity and reducing interference.
Wireless Transmission
- Radio waves are modulated for the wireless transmission of data, allowing for communication over distances without physical connections.
Encoding Data in Metal Wires
- Electrical impulses are used to encode data in metal wires within cables, facilitating data transfer in wired networks.
Glass or Plastic Fibers
- Glass or plastic fibers in fiber-optic cables are primarily used to transmit light signals, enabling high-speed data communication.
Commonly Used Cable Type
- Twisted-pair cable is commonly used for telephone communications and modern Ethernet networks due to its cost-effectiveness and sufficient performance.
