A network is an interconnection of devices that allows communication between them to share network resources. There are different types of networks including local area networks (LANs) that connect devices within a small geographic area like a home or office, and wide area networks (WANs) that connect multiple LANs across cities or countries. Network devices like hubs, switches, and routers help facilitate this connectivity, with switches improving on hubs by only sending traffic to the intended recipient device to avoid congestion. Various cable types like coaxial, twisted pair, and fiber optic are used to physically connect the network devices and components.

7. HUB
A hub is a device into which you can connect
all devices on a home network so that they
can talk together.
Hubs physically cross-connect all their ports
with one another which causes all traffic sent
from a server to the hub to be blurted out to
all other servers connected to that hub
whether they are the intended recipient or
not.

8. Switch
A switch is also a device into which you can
connect all devices on a home network so
that they can talk together.
Unlike a hub, traffic sent from Server A to
Server B will only be received by Server B.
The only exception is broadcast traffic which
is blurted out to all the servers
simultaneously.

10. Router
 Router is device which is used to enable
communication possible between two or
more different networks present in
different geographical locations.

11. NIC
 The Network interface card is frequently
called a NIC. Currently, the most
common types of NIC used in the home
are Ethernet and wireless Ethernet
cards.
