The internet has become a
necessity these days. No one can imagine a life without the internet. The
internet connects the whole world in the form of a global village. A person or
business not using the internet is considered as an obsolete and outdated and
there is no guarantee of their success. Today, different types of devices are
available for the internet connection, depends upon the type of connection and
its speed. However, the devices that we see at the front end like the USB
dongle internet device are not the only players. These devices work with the
help of other devices. The best 3
network devices are Network switches, routers and hubs.
One of the mentioned 3 network devices is network switch. The
network switch is used to connect different network segments. The network
switch plays an integral part in most LANs.
The LAN consists of different switches, used for connecting networking
segments. The number of switches used in
small LAN devices is less than the number of switches present in bigger LANs.
At times single switch is enough for home or small office LAN. These switches
work in every layer of the networking model. A switch that is used in more than
one layer is called a multi-layer switch.
The second mentioned device out
of mentioned 3 network devices is a router.
A router is a device that transmits the data packets between different computer
networks. The router is connected to different lines of data network. When the
data receive in the form of packet to any of the data lines, it reads the given
address and sends it to its proper destination. The router serves as the
traffic constable and directs the network traffic to its correct location. There
is series of routers that works for sending data to its correct destination.
The data travels through these routers and keeps travelling until it reaches to
its destination. The examples of data that passes through these routers are emails,
web pages and file transfer.
The third most important device
of mentioned 3 network devices is a
hub. This number 3 network device is
like a small rectangular box that works on the power supply from the socket.
The hub combines the 3 network
devices and multiple computers to form one network segment. All the computers
and devices, connected through hub, can directly communicate with each other. A
hub consists of a number of ports for network cables. The number of ports
varies with the size of the hub. The hub receives the data packet, transforms
it into the desired form and then distributes it to all the devices present in
the network. There are 3 network
hubs; they are known as passive hubs, active hubs and intelligent hubs. Each of
these hubs has different functions and features.
The mentioned 3
network devices are commonly used for the networking purpose. No networking
can take place if anyone of these devices is missing. Each of these devices has
different functions that contribute towards the formation of a network segment.
