1.Hub:
Hub is a networking device which is
used to connect multiple network hosts
2. Switch:
A switch does ‘filter and forwarding’
which is a more intelligent way of dealing with the data packets
3.Modem:
v Our computer generates
binary data or digital data in forms of 1s and 0s and on the other hand, a wire
carries an analog signal and that’s where a modem comes in.
v A modem stands for (Modulator + Demodulator).
That means it modulates and demodulates the signal between the digital data of
a computer and the analogue signal of a telephone line.
4.Router:
v Routers are located
at gateways
v A data packet is
typically forwarded from one router to another
router through the networks that constitute the inter-network until it reaches its
destination node.
v If we want to connect 2
same network means, Switch is enough
(10.0.0.0 to 10.0.0.0). If we want to connect 2 different network means, we need
Router (10.0.0.0 to 20.0.0.0)

5.Bridge:
v Divide a large network in
to small segments
v If a router connects two
