A router operates using Layer 3 decisions based on IP addresses. A switch functions at Layer 2, handling MAC addresses. A bridge performs similar tasks but relies entirely on software, whereas a switch uses hardware like a switch chip or ASIC for main forwarding. A Wireless Access Point acts as a bridge with one or more wireless ports, supporting multiple clients. A SOHO router integrates all these roles: it connects to the WAN via a LAN port, links to a switch (which connects to four Ethernet ports on the outside), and includes a bridge that combines the router’s LAN, the switch uplink, and wireless radios. It also features a WAP for the wireless radios within the bridge.
Modem routers are devices that connect directly to the internet through a modem, which receives an IP address from your service provider. The modem essentially handles the verification of your internet connection. While this comparison isn’t perfect, it works well for understanding their roles. A router, on the other hand, assigns public IP addresses to multiple devices in your local network and routes traffic between them and the wider internet. It uses MAC addresses to direct internal data to the correct destination. Switches or access points operate similarly within a single subnet, forwarding data based on MAC addresses. In more complex setups with separate networks, communication must pass through the router using IP addresses. However, not all routers come with built-in wireless capabilities, and many modern models include them by default.
