Summary The basics of device communications.

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:

Wired 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.
