Each networking device has a different role in a computer network. They also work at different levels of a network doing separate functions. Keep reading to learn more about different types of networking devices and what each of these type does. At the point of time when you go to complete some of your work on your PC, you probably won’t understand that you depend on more than your Internet browser to get data, shop, or send emails. You’re also depending on an IP address that recognizes your PC and wiring network. Networks are more than PCs and wiring. Networks also incorporate specific hardware devices.

If we take a closer look at the types of networking devices, they work at different layers of the computer networks. Different layers of computer networks are like different zones of a computer network with specified works, which are also called network protocols. So, now we will try to understand about the different networking devices used at different levels.

1. Network Hub

This sort of device is used to connect multiple number of network hosts. It is also used for data transfers throughout the network. The data is moved in form of packets on a computer network. At the point when a host sends an information bundle to a system center, the center point duplicates the packet to the entirety of the ports that are associated. The ports know about the data and the port that the packet is expected for then claims the packet.

2. Network Switch

A switch also works at the layer of the LAN, but a switch is more intelligent than a hub. While a hub does data forwarding, a switch does filter and forwarding. This is a more intelligent way of dealing with data packets. When a packet is received at one of the interfaces of the switch, it filters the packet and sends it solely to the intended receiver.

3. Router

A router is a network device that’s responsible for routing traffic from one network to another. The two networks could be a private company network to a public network. You can think of a router as a traffic police officer directing network traffic to different directions.

4. Bridge

If a router connects two different types of networks, then a bridge connects two sub-networks as a part of the same network. To visualize this, picture two different labs or two different floors connected by a bridge.

So, these are the different types of networking devices that are found and used in a networking system and are derived to work for the transfer of data from one system to another through a defined route.
