Router and Switch are both essential but distinct pieces of a network! Here's a breakdown of the key differences between a router and a switch:
- Primary Function: Switch Connects devices within a local network (LAN) but router a Connects different networks (LANs or WANs)
- Data Forwarding: In switch based on MAC addresses (Layer 2) while for router based on IP addresses (Layer 3)
- Addressing: Switch Uses MAC addresses for device identification within the LAN while router uses IP addresses for network and device identification across networks
- OSI Layer: Switch work on Layer 2 (Data Link Layer) and router at Layer 3 (Network Layer)
- Broadcasts: Switch Limits broadcasts to the local network (VLANs can further segment. Router does not typically forward broadcasts between networks (except in specific configurations)
- Network Complexity: Switch primarily for local connectivity and router more complex, handles routing between different networks
- Configuration: Switch usually less configuration needed (unmanaged switches are plug-and-play) router often requires configuration for routing protocols, firewalls.
- Typical Use Case : Switch Connecting computers, printers, and other devices in a home or office and router connecting a home network to the internet, connecting different offices together
