INTRODUCTION TO
COMPUTER
NETWORKING
 A computer network is a group of
interconnected devices that can
communicate with each other. These devices
can include computers, servers, printers, and
routers.
 The purpose of a computer network is to
share resources such as files, software, and
hardware devices. Networks also allow for
communication between users, whether it be
through email or instant messaging.

TYPES OF NETWORKS
TYPES OF
NETWORKS
 There are several types of computer networks, including
local area networks (LANs), wide area networks (WANs),
and metropolitan area networks (MANs).
 LANs are typically used in small areas such as homes or
offices, while WANs cover larger geographical areas such
as cities or countries. MANs are somewhere in between,
covering a larger area than a LAN but not as large as a
WAN.
Wireless Local Area Network (WLAN):
A WLAN is a type of LAN that uses wireless
technology, such as Wi-Fi, to connect
devices. WLANs are often used in public
spaces like airports, coffee shops, and
libraries to provide internet access to users.
Storage Area Network (SAN): A
SAN is a specialized network that is
used to provide block-level access to
data storage. SANs are commonly
used in data centers and other
environments where large amounts of
data need to be stored and accessed
quickly.
Virtual Private Network (VPN): A VPN is a network that
uses encryption and other security protocols to create a
secure connection over a public network, such as the internet.
VPNs are often used by remote workers to access corporate
resources securely.

TOPOLOGIES
NETWORK TOPOLOGIES
A network topology refers to the physical
layout of a network. There are several different
topologies, including bus, star, ring, and mesh.
The bus topology involves all devices being
connected to a single cable, while the star
topology has all devices connected to a central
hub. The ring topology connects devices in a
circular pattern, and the mesh topology has every
device connected to every other device.

NETWORKING
PROTOCOLS
NETWORKING PROTOCOLS
Network protocols are a set of rules that govern how data
is transmitted over a network. Some common
protocols include TCP/IP, HTTP, and FTP.
TCP/IP is the most widely used protocol and is responsible
for ensuring data is transmitted accurately and reliably.
HTTP is used for transferring web pages, while FTP is
used for file transfers between devices.
05
NETWORK SECURITY
NETWORK SECURITY
Network security is a critical aspect of computer networks, as it protects
against unauthorized access and cyber attacks. There are several
measures that can be taken to secure a network, including firewalls,
encryption, and regular updates.
Firewalls act as a barrier between a network and the internet, while
encryption ensures that data cannot be read by unauthorized users.
Regular updates help to patch any security vulnerabilities in the
network's software.


FUTURE OF
COMPUTER
NETWORK
As technology continues to advance, so too will
computer networks. One emerging technology
is the Internet of Things (IoT), which involves
everyday devices such as appliances and cars
being connected to the internet.
 Another trend is the move towards cloud
computing, where data and applications are
stored on remote servers rather than locally on
individual devices. This allows for greater
flexibility and scalability in network
management.
