Wired Network Connections:Copper Cables:
Use electricity to transfer data.
Consist of multiple wires, grouped and insulated to prevent interference.
Suitable for short connections in businesses.
Benefits: Cost-effective, good conductor of electricity.
Limitations: Not suitable for long distances, potential for interference
without proper insulation.
Fiber Optic Cables:
Use light to transfer data (binary) through thin, flexible glass or
plastic.
Require separate pathways for sending and receiving data.
Benefits: Higher bandwidth, faster data transfer, suitable for long
distances.
Limitations: More expensive, less flexible than copper, can be brittle.
Wired vs. Wireless Networks:

More stable and reliable.
Harder to intercept data, providing better security.
Longer range compared to wireless networks.
Limitations: Less flexible, harder to add or change devices, can become
messy and hazardous.
Wireless Networks:
More flexible and easier to add new devices.
No physical wires, reducing mess and hazards.
Limitations: Potential for more errors, easier to intercept data, shorter
range.
