In your Networking career. there are some basic device you ought to be conversant with.


A hub is a common connection point for devices in a network. 
Hubs are commonly used to connect devices to a LAN. It contains multiple ports. 
When a packet is sent at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
In a hub packets is received by all the devices connected to it.


A network bridge is a computer networking device that creates a single aggregate network.

basically a bridge, bridges or joins two networks that are using the same communication protocol,
from multiple communication networks or network segments. A bridge work with Mac-addresses
Bridging is performed in the first two layers of the OSI model, below the network layer.


A network switch, a layer 2(Data link) device,and also a layer 3(Network layer) device in the OSI model.
For the Layer 2 Switch it uses only mac-address, while the layer 3 switch uses both ip address and mac-address

A switch is a computer networking device that connects devices together on a computer network, 
by using packet switching to receive, process and forward data to the destination device.
A switch uses mac-addresses and it’s sends packet to it’s respective destination.


A router is a networking device that forwards data packets between computer networks. 
Routers perform the traffic directing functions on the Internet. 
its a layer 3 device of the OSI model, it uses IP address.
A data packet basically is pushed from one router to another 
through the networks that comprises the internetwork until it reaches its destination node.
