HUB-it is a kind of repeater, it is used to extend a
network but we cant able to send a particular data to a
particular host.It is a layer 1 device uses to send datas
in the form of bits and it uses hardware address to send
bits
SWITCH-it is a bridge which has higher number of ports, it
is a layer two device which uses hardware address(MAC
address)to send datas in the form of frames.
ROUTER-it is used to send the data in the remote
network,packet switching, path selection are some other
functions.It uses to IP address to send data.Datas are in
the form of packets

HUB - is a non intelligent device. it just broadcat data
what data will come. it doesnt know what is source host
what is the destination. it is just like multiport repeter.
and it is layer1 device.
Switch - it is a intelligent device. it cant do broadcast.
it can done flooding. also done multicats and unicats. it
is work with mac address. so it is a layer 2 device.
Router - it is mainly used to connet two diff networks. it
is work with ip address. it is a layer 3 device.

another network, while a switch works in a single network

Answer / a
HUB simply passes all the information it receives to all the
devices connected to its port receives that information.
SWITCH knows which devices are connected to its ports and
forward appropriate port only.
This allows simultaneous communication across the switch
improving bandwidth.
ROUTERS are first receiver of any connection connected to it.
It then allows to receive connection from it.
