Networking Devices: The Information You Need To Know
In today’s post, we will know what is networking devices? A device used to expand a network is called a networking device, meaning a networking device is a device by which two or more computers or electronic devices are connected so that they can share data among themselves.
Following are the networking devices
Repeater is an electronic device that works on the physical layer of the OSI model. It is used to increase transmission so that the signal can cover longer distances. Meaning Repeater is used to regenerate Signals before they are Weak. Repeater receives singles and sends them forward by Regenerate or Replicate.
There are two types of repeater
Analog Repeater – This repeater does only Signals
Digital Repeater – This repeater reconstructs the signals and removes the error from them and sends them forward.

Hub is a networking device, it works on the physical layer of the OSI model, it is used to connect many computers in the network.
When a user sends data to another user in the network, Hub broadcasts it to the network by putting the MAC address of the destination on that frame, and the destination host whose MAC address matches in the network, the data is delivered. are | Hubs perform Half Duplex communication, meaning they cannot send and receive host data simultaneously.
Types of Hub
Hubs are of two types.
Passive Hub – These hubs work without power supply, in which signals are sent as they come.
Active Hub- Signals in this type of hub are regenerated like a repeater and sent forward. Power supply is required for Active Hub.
Due to some of its shortcomings, it is no longer used in the network.
Characteristic of Hub
- ALWAYS do Broadcast
- Layer 1 device
- Shared bandwidth
- Less no of ports
- Doesn’t learn mac address

Switch works on the Data Link Layer and Network Layer of the OSI Model. The Switch is used to connect multiple computers among themselves Switch is an intelligent device because it has memory to maintain all the host addresses of the network, which host in this address table is connected to which port of the switch. This is also a store.
To send data in the network, the switch broadcasts the first time and stores the MAC address of everyone in its table, when the addresses and port numbers of all the hosts come in the switch, then the switch sends data packets only to the one whom the sender has sent
Switch is a Full Duplex Device in which the host can send and receive data simultaneously.
Characteristic of Switch
- Which connects two or more computers together
- Many no of ports
- Learn mac address

Bridge is also a computer networking device and it works on the Data Link Layer of The OSI L Model. The bridge sends packets between two network segments that use the same communication protocol. This bridge has two ports, one incoming and the other outgoing, so that the other part of the network is connected. The bridge checks the destination address before sending the data. If the destination was in another part of the network of the MAC network, then sends the data. Means the bridge has to decide whether to send the data packets to the other side of the Ethernet segment or not.
Advantage of network bridge
- Increases Network Length
- Prevents Bandwidth Waste
Router is an inter networking device which is used to connect two different networks together. It works on the Network Layer of OSI Model. Router sends data from one network to another. Then the next few switches, the router maintains its own ROUTE Table.
Components of Router
Like a router computer system, it is made up of many components. Some of the basic components of a router are as follows.
Types of Protocols
Router uses 2 types of protocols to send data to the network.
This protocol carries data and defines logical addressing. In this type of protocol, the device is manually given an IP.
IP, IPX, AppleTalk.. This protocol is reduced within the Routed Protocol.
Protocols of this type do Path Determination between Routers, with the help of these, Routers update their Routing Table.
RIP, IGRP, EIGRP, OSPF.. etc. These protocols work under Routing Protocol.
