Networking Devices You Should Be Familiar With

In the world of computer network, different hardware and networking devices consist of different roles. The computer networking devices come up with different names and with different purposes and functions.  The networking devices also operate at various segments of computer networking carrying out different functions.

While dealing with different devices, they appear with different layers of computer hardware and network. These layers are similar to the computer networking based on the particular work which is also known as network protocols.

For an instance, the key purpose of LAN cable is to connect the computer with local area network and that of Wi-Fi router is to send and receive data between you and your internet connection. This shows network devices comes up serve with different determinations.

Are you aware of these networking devices?

If not, let me explain it for you.

Here are some Networking devices you should be aware of:

1.Network Hub

One of the basic icons of networking device, Network hub services at the physical layer and also links networking devices physically together. Basically, they are utilized in network with twisted pair cabling for connecting the devices.

Network hub works with the purpose of connecting different network hosts. This networking device is also well-equipped for data transfer. Data transferred is carried out through the packets on the computer networks.

Thus, hosts convey data packet to network hub and it replicas the data packets to its every port linked with. Similarly, every port is aware of the data and the port intended and privileged for the packet.

Due to its working procedure, a hub may not be protected. In addition, repetition of similar data packets on every interface or port may decrease the speed, making more jammed which may obstruct the use of a network switch.


Switches are the connection points of an Ethernet network. Similar to hub, the devices within switches are interconnected with one another via twisted pair cabling. But, the way hub and switch gets data is a bit different as hub sends data to every port on the devices and switches transfer it just to the port linked to the end device. Switch carries out its function with instinctive learning of MAC address of the devices lined with it.

As the transmission of data signals are defined properly in the switch and the presentation of network improved accordingly. Also, switches work in the full-duplex approach where devices are allowed to send and receive data from switch concurrently distinct in half-duplex mode.

The transmission speed in switch is double of the Ethernet hub relocating the connection. In networking, the progress in the performance is evaluated in the wide-ranging procedure of switches these days.


You must be familiar with a modem. They are one of the useful networking devices in our day to day life. You must have observed that you receive your internet connection via different types of wires to your home. These wires work with the main purpose bring out the internet data outside to the world of web.

In addition, our desktop devices produce binary data or digital data in 0 and 1 which also brings up Analog signal. This is the place where modem appears to serve.

Modem is an acronym for Modulator and Demodulator which indicates it modulates and demodulates the signal among digital data on a desktop device and analogue signal of telephone device.


Bridges are computer network device developing the connection among other bridge networks that use similar protocol. In OSI model, it serves at Data Link layer and links the various networks together and communicate with one another. Also, it links two sub networks as a part of the similar network.

Together with developing the larger networks, bridges are also employed to slice large network into small piece. The bridge carries out its task by putting itself among the two shares of two physical networks and control the flow of data among them.


Network layer device Routers are mostly recognized as Layer 3 device of OSI model that appears with logical addressing information in Network header of a packet alike IP address. It creates a huge complex network with traffic routing. It contains the capability for connecting different LANs on similar protocol with the competence to limit the flow of transmission.

Firstly, router consists of a hardware device or a computer system that enclose over one network interface and routing software. When a router obtains data, it regulates the destination by looking at the header of the packet.

While determining the address, it looks in its routing table to get familiar with some approach to get into the destination and move onwards the packet to the higher stage of the route.

Wrapping Up,

These are some networking devices working at various segments of a computer network carrying out different functions.

If you have any hardware and network related problem, then do come to us. We will help you get rid of these problems and make your device fit and healthy.
