5. What are Basic
Networking
Concepts?
 Networking is the
backbone of modern
communication, allowing
us to connect with people
and information from all
around the world.
 At its core, networking
involves the exchange of
data between two or
more devices, whether
they are computers,
smartphones, or other
digital devices.

6. The
Importance of
Networking
 Networking is an essential component of modern
technology, enabling us to connect with others and
access information quickly and efficiently.
 By networking our devices, we can increase
productivity, collaborate more effectively, and
communicate in real-time. Additionally, networking
allows us to access a wealth of information that would
otherwise be unavailable to us.

7. Characteristics
of Network
Resource sharing
Communication speed
Back up
Scalability
Reliability
Soft ware and hard ware sharing
Security

8. Types of
Network
devices
 HUB
 SWITCH
 BRIDGE
 GATEWAY
 MODEM
 ROUTER
 REPEATER

9. Types of
Network
1.Personal Area Network (PAN)
2.Local Area Network (LAN)
3.Metropolitan Area Network (MAN)
4.Wide Area Network (WAN)

10. Personal Area
Network (PAN)
 PAN stands for Personal Area Network
 It ranges from 0 to 10 meters
 Also Known as HAN (Home Area Network)
 Example : computer network at our home

11. Local Area
Network (LAN)
 A Local Area Network (LAN) is a group of
computers and network communication devices
within a limited geographic area, such as an office,
building.
 It provides High data transfer speeds ranges up to
150 meter
 Generally less expensive technologies

12. Metropolitan
Area Network
(MAN)
 A MAN is larger than a LAN but smaller than or equal in
size to aWAN.
 The size range anywhere from 5 to 50km in diameter.
 MANs are typically owned and managed by a single
entity.

13. Wide Area
Network
(WAN)
 AWide Area Network (WAN) interconnects LANs. It is
not restricted to a particular geographic area and
may be interconnected around the world.
• Multiple interconnected LANs
• Generally more expensive technology

14. NETWORKTOPOLOGY

15. BUS
TOPOLOGY
• a single cable connects each workstation in a
linear, daisy-chained fashion.
• signals are broadcasted to all stations, but stations
only act on the frames addressed to them.

16. STAR
TOPOLOGY
 In a star topology, each station is connected to a
central hub or concentrator that functions as a multi-
port repeater. Each station broadcasts to all of the
devices connected to the hub. Physical LAN topologies
are usually characterized as either bus or ring.

17. RING
TOPOLOGY
• Unidirectional links connect the transmit side of
one device to the receive side of another device.
• Devices transmit frames to the next device
(downstream member) in the ring.

18. MESH
TOPOLOGY
 It is a point-to-point connection to other nodes or
devices.Traffic is carried only between two devices or
nodes to which it is connected. Mesh has n(n-2)/2
physical channels to link n devices.

19. HOW TO CONFIGUREYOUR ROUTE

20. CONNECT
YOUR ROUTER
 The device that has to be connected to theWi-Fi router, has to
have an appropriate network adapter.The first step to configure is
to physically connect your router to a modem provided by your
ISP with an Ethernet cable, by following these steps:
 Firstly, unplug or turn off the cable or DSL modem.
 Plugin your wireless router and connect the network cable into the
port on the router that is labelled "Internet" or "WAN."
 Connect the other end to the cable or DSL modem and start up
the modem.
 Do not try to connect any devices such as laptops or tablets until
you have a high strength signal indicating aWAN connection on
both the router and modem.

21. Access the
router's interface
and build it
 Connect an Ethernet cable to one of the LAN ports on the router and
the other end to the Ethernet port of the laptop.
 Click to open "Network and Internet" and then "Network and Sharing
Centre."
 From the left-hand window, click "Change adapter settings."
 Right-click on "LocalArea Connection" and then click on "Properties."
to select the IP version.
 Hold the cursor on “Internet ProtocolVersion 4 (TCP/IP v4)” and once
again, click "Properties."
 Push the click on "Use the following IP address:" and enter the
information as shown in the image above.
 Once the changes are done, open up a browser and go to the web
address using the account name "admin" and password "admin."This
is now all set to configure security and other settings.

22. Configure
security and IP
addressing
 Change the default administrator password which is usually under
the "System" tab or page of the interface. Just enter a new
password in the new password field.
 Change the router's default SSID.The SSID is the broadcasted
name of the unique wireless network you own. Use a unique name
to avoid confusion.
 Assign security. Go into the router's wireless security page. Opt for
WPA security, as it requires clients connecting to it to use a
password, for connecting.
 Set up IP addressing. For most networks, the router comes at its
default DHCP setting.
 Disconnect the laptop and reboot it.When the laptop comes back
from reboot the user can see the SSID name of your wireless
network and be able to connect to it with the password you
created.

23. Set up sharing
and control
AND
Set up user
accounts
 Select the User Accounts icon.The User accounts
settings will allow you to configure your account.
 To add and configure other devices to access the
network, from User Accounts, click on "Manage User
Accounts," and then click on the "Advanced" tab.
 Under "Advanced User Management" click "Advanced"
and select the user and add them to your network.The
advanced setting also comes with the Wi-Fi router
recharge plans.

24. CONCLUSION
 During the internship, I have virtually gained the knowledge of
communication networks.
 Felt the experienced that how data communication networks devices
(e.g. router, switches etc) are configured and this was enhanced my
industrial knowledge in this field.
 In conclusion, understanding basic networking concepts is crucial in
today's digital age. It allows individuals and organizations to connect
devices, share information, and communicate effectively. By knowing
the different types of networks, topologies, protocols, and security
measures, one can ensure reliable data transmission and protect
against unauthorized access.
