How Switch Works

1. Data In – devices like PCs, VoIP phones send traffic into the switch.

2. Packet Switching – the chipset checks MAC addresses and forwards packets only to the correct destination port.

3. Data Out – traffic is sent to servers, laptops, or other connected devices.

What’s Inside a Switch

CPU – controls data processing

RAM – temporary storage for packet handling
Switching Chipset – the heart of packet forwarding

Flash Memory – stores firmware & configs

Ethernet Ports – high‑speed wired
connections

SFP/SFP+ Ports – fiber optic uplinks

Console Port – for management & configuration

Power Supply & Cooling Fan – keep it running safely
