Which of the devices will connects three network segments

The device that connects three network segments is a network bridge. Here are the steps explaining how it works:

1. A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments.

2. This function is called network bridging. Bridging is distinct from routing, which allows multiple different networks to communicate independently while remaining separate.

3. In the OSI model, bridging acts in the first two layers, below the network layer.

4. Above the network layer, the transport-layer protocol translates smaller pieces of data into larger packets to be transmitted.

5. This bridging technology involves the bridging of three network segments. Network segments are parts of a computer network. They can be connected by different physical devices such as network bridges, switches, hubs, and routers.

6. The bridge examines each message on each segment and decides whether to forward it or not.

7. A bridge can also connect networks and maintain the traffic separation between them.

8. It can also connect more than three network segments, which makes it a versatile tool in networking.

9. In summary, a network bridge connects three network segments by examining and forwarding messages between them.
