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!
