CCNA Networking

Certificate

What is networking ??
 Computer networking refers to interconnected computing devices
that can exchange data and share resources with each other.
 These networked devices use a system of rules, called
communications protocols, to transmit information over physical or
wireless technologies.
 Almost every field of science and electronics has something to do
with Data networks and networking technology. Thus, networking
technology touches almost every sphere of modern life

Networking using Cisco packet
tracer
 Cisco certified Network Associate (CCNA) installs, configure and
troubleshoot networks using products from Cisco, a major
provider of networking services.
 The CCNA is designed to validate your knowledge on
fundamental networking concepts often requested in
networking roles in IT positions.
 Cisco Packet tracer can be used to create complicated network
typologies, as well as to test and simulate abstract networking
concepts.
 It acts as a playground for you to explore networking and the
experience is very close to what you see in computer networks.

Component used in
Networking

Cabling
 Cabling- Networking cables are networking hardware used to
connect one network device to other network devices or to
connect two or more computers to share printers, scanners
etc. Common cables used are given below-
1. Straight cable
2. Crossover cable
3. Console Cable (Rollover cable)
4. Auxiliary cable

Router and switch
 A router is a device that connects two or more packet-switched
networks or subnetworks.
 A router serves two primary functions: managing traffic between these
networks by forwarding datconnection to their intended IP addresses,
and allowing multiple devices to use the same Internet connection.
 Network switch is networking hardware that connects devices on a
computer network by using packet switching to receive and forward
data to the destination device
 A network switch is a multiport network bridge that uses MAC
addresses to forward data at the data link layer (layer 2) of the OSI
model

Hub
 A Hub is a hardware device that divides the network
connection among multiple devices. When computer
requests for some information from a network, it first sends
the request to the Hub through cable.
 The process used by the Hub consumes more bandwidth and
limits the amount of communication.
 Nowadays, the use of hub is obsolete, and it is replaced by
more advanced computer network components such as
Switches, Routers.

End to end encrypted message
network using Cisco packet tracer
 Like WhatsApp, where messages are end to end encyrpted, the
backend topology that is used to make this possible is elaborated
here.
 In this we created internet connection between different end users
using DNS.
 Routing is done to send message from best suited path.
 IP addressing and MAC addressing class types were used.
 Coding is done in Physical, data link layer and network layer of OSI
model

IP Addressing
 IP address stands for internet protocol address; it is an identifying number
that is associated with a specific computer or computer network.
 An internet protocol (IP) address allows computers to send and receive
information.
 There are four types of IP addresses: public, private, static, and dynamic.
 An IP address allows information to be sent and received by the correct
parties, which means it can also be used to track down a user’s physical
location in some instances.
 There are five classes of addressing
Class A, class B, class C, class D, class E.

MAC addressing
 A media access control address (MAC address) is a
unique identifier assigned to a network interface
controller (NIC) for use as a network address in
communications within a network segment.
 MAC addresses are primarily assigned by device
manufacturers, and are theMAC addresses are
recognizable as six groups of two hexadecimal digits,
separated by hyphens, colons, or without a
separator.
 MAC addresses are recognizable as six groups of two
hexadecimal digits, separated by hyphens, colons, or
without a separator.

OSI Model

Routing
 Router is a deviceby which communication takes place between two
networks. IP Routing is the process of sending packets from a host
on one network to another host on a different network.
Types of Routing:-
1. Static routing
2. Default Routing
3. Dynamic Routing

Switching
 In large networks, there can be multiple paths from sender to
receiver. The switching technique will decide the best route for data
transmission.
 Switching technique is used to connect the systems for making one-
to-one communication.

Virtual private network (VPN)
 It is used private to private over public
network.
 VPN stands for “virtual private network”
— a service that helps you stay private
online. A VPN establishes a secure,
encrypted connection between your
computer and the internet, providing a
private tunnel for your data and
communications while you use public
networks.
