Network devices used in computer networking:-

 

1. Repeater 🔄: Think of a repeater as the network’s cheerleader, working at the physical layer 🌐. Its job is to boost and regenerate signals, preventing them from becoming weak or corrupted during transmission. It’s like a signal superhero 🦸‍♂️.

2. Hub ☁️: Hubs are like the town squares of the network, with multiple ports for connecting different branches. However, they lack intelligence and can’t filter data. Instead, they broadcast data packets to all connected devices like an enthusiastic town crier 📣.

3. Bridge 🌉: Bridges are the traffic cops of the network world, operating at the data link layer. They smartly filter content by reading MAC addresses, ensuring data goes where it’s supposed to, much like guiding cars on different lanes of a bridge 🚗.

4. Switch 🔀: Switches are the intelligent traffic managers 🚦 of the network. They operate at the data link layer and efficiently forward data packets between devices within a network. Think of them as traffic directors, ensuring data gets to its destination without congestion 🚗🚙🚛.

5. Router 🌐: Routers are the navigators 🧭 of the network, working at the network layer. They use IP addresses to guide data packets between different networks. Routers are like the postal service of the internet, directing data to the correct addresses 📬.

6. Gateway 🌍: Gateways are the translators 📚 of the network world. They connect two different networks that use different protocols, making sure they can understand each other’s language. Gateways are like interpreters bridging the communication gap 🗣️.

7. Network Interface Card (NIC) 🖧: NICs are the network’s communicators, residing in individual devices like computers and servers. They provide the interface between the device and the network, allowing data to be sent and received. NICs are like the device’s voice 🗣️ in the network conversation.
