Difference between Bridge and Gateway
Prerequisite – Network Devices Bridge: Bridge is a network device which works in data link layer. Bridge connects two different LAN working on same protocol. Also In bridge, format of packet is not changed.
Gateway: Gateway works in OSI model’s all layer. It converts the protocol. Gateway will settle for and transfer the packet across networks employing a completely different protocol. In gateway, format of packet is changed which oppose to the bridge.
Now, we shall discuss the difference between bridge and gateway:
S.NO | Bridge | Gateway |
---|---|---|
1. | Bridge works in data link layer. | While it works in all layer. |
2. | Bridge connects two different LANs. | While it converts the protocol. |
3. | Bridge connects two different LAN working on same protocol. | While gateway will settle for and transfer the packet across networks employing a completely different protocol. |
4. | In bridge, data or information is in the form of packet. | Whereas in gateway, data or information is also in the form of packet. |
5. | In bridge, format of packet is not changed. | While in gateway, format of packet is changed. |
