Comparision table for different types of Network Devices
December 21, 2024
Here is a comparison table for different types of network devices:
| Network Device | Function | Layer of OSI Model | Main Purpose | Data Transmission Type | Example Use Case |
|---|---|---|---|---|---|
| Hub | Connects multiple devices in a network, broadcasting data to all devices. | Physical Layer (Layer 1) | Simplifies device connections, but inefficient due to broadcast. | Broadcasts data to all connected devices. | Small networks, simple connections (rarely used today). |
| Repeater | Amplifies or regenerates weak signals to extend the range of a network. | Physical Layer (Layer 1) | Extends network reach by boosting signals for longer distances. | Regenerates and amplifies signal. | Long-distance networks, large office buildings. |
| Bridge | Connects two or more network segments and filters traffic between them. | Data Link Layer (Layer 2) | Reduces traffic between segments by filtering data and forwarding only necessary traffic. | Filters and forwards data between network segments. | Dividing large networks into smaller, manageable segments. |
| Switch | Connects multiple devices within a network and directs data to the right device. | Data Link Layer (Layer 2) | Increases network efficiency by sending data only to the intended recipient. | Directs data to specific devices (based on MAC address). | Office networks, large-scale network communication. |
| Router | Directs data between different networks, such as connecting a home network to the internet. | Network Layer (Layer 3) | Routes data based on IP addresses, connects local and remote networks. | Routes data based on IP addresses. | Internet connection, local area networks. |
| Gateway | Acts as a translator between different protocols and networks. | Multiple Layers (Mainly Application & Network Layer) | Connects networks using different protocols and translates data between them. | Protocol conversion, forwarding data. | Connecting different networks (e.g., LAN to internet). |
| Brouter | Combines the functions of a bridge and router, filtering and routing data. | Data Link Layer & Network Layer | Bridges traffic within segments and routes data between networks. | Filters and routes data (mix of bridge and router). | Large networks needing both routing and filtering. |
