Final answer:
Transmission carriers in LANs include Ethernet, which uses copper wires; Fiber optic, which transmits data via light, and Coaxial cable, used for cable internet and TV.
Step-by-step explanation:
The three types of transmission carriers used in Local Area Networks (LANs) are:
- Ethernet
- Fiber optic
- Coaxial cable
Ethernet is a widely-used technology for network connectivity that uses copper wires to transmit data. Fiber optic cables, on the other hand, utilize light signals to send information over long distances with low loss, high bandwidth, and reduced crosstalk. This makes them highly suitable for extensive communication networks like the internet. Coaxial cables, consisting of a central metal conductor surrounded by insulation and another conducting layer, are commonly used for cable internet and TV services.
