- Ethernet standards: 1000BASE-T (Gigabit over Cat5e/Cat6), 10GBASE-T (10G over Cat6A), fiber options for longer distances.
- Wireless standards: 802.11a (5GHz), 802.11b/g (2.4GHz), 802.11n (dual-band), 802.11ac/Wi-Fi 5 (5GHz), 802.11ax/Wi-Fi 6 (dual-band, OFDMA).
- VLANs logically segment a switched network; traffic between VLANs requires a router or Layer 3 switch.

- Firewalls filter traffic using rules; stateful firewalls track connection state; next-gen firewalls add application awareness.
