Quick Reference - Wired vs Wireless
Wired (Ethernet):
- Method: Physical cables (Cat5e/Cat6)
- Advantages: Fast (1-10 Gbps), secure, reliable, low latency
- Disadvantages: No mobility, cables needed, installation effort
- Best for: Desktops, gaming PCs, servers, smart TVs
Wireless (WiFi):
- Method: Radio waves (2.4/5 GHz) via WAP/router
- Advantages: Mobility, convenient, no cables, easy setup
- Disadvantages: Slower, less secure, interference, variable performance
- Best for: Laptops, phones, tablets, smart home devices
The Golden Rule:
Choose wired when performance, security, and reliability matter (stationary devices). Choose wireless when mobility and convenience matter (mobile devices). Modern networks use BOTH!
