3. INTRODUCTION
The Internet is a vast global network that enables the exchange of
information between billions of devices worldwide.

4. - 1969: ARPANET, the precursor to the Internet, is
established by the U.S. Department of Defense.
- - 1983: The TCP/IP protocol, the backbone of the
Internet, is standardized.
- - 1990s: The World Wide Web is introduced,
revolutionizing online content.
- - Rapid growth and commercialization follow.
- - Web 1.0: Static web pages, limited user
interaction.
- - Web 2.0: Dynamic, interactive web (e.g., social
media, YouTube).
- - Web 3.0: Emerging technologies like AI,
blockchain, and IoT.

DEVICES
• The Internet involves a multitude
of devices, including computers,
servers, smartphones, routers, and
more. Each of these devices is
assigned a unique address known
as an IP (Internet Protocol)
address.
DATA TRANSMISSION
• When you send or request data
over the Internet (e.g., visiting a
website, sending an email, or
streaming a video), your device
breaks the information into smaller
packets. These packets are then
sent to their destination through
various transmission media

6. EXAMPLES OF IOT

TRANSMISSION MEDIA
• Data is transmitted through various
means, including:
• Fiber Optic Cables - Used for long-
distance, high-speed transmission
through the transmission of light
signals.
• Wireless Signals - Wi-Fi, cellular
networks, and satellite connections
for wireless communication.
ROUTING
• Data packets are directed through
the Internet using routers. Routers
are like traffic controllers, deciding
the most efficient path for data to
travel from the source to the
destination. They use routing
tables and algorithms to make
these decisions.

INTERNET PROTOCOLS
• The Internet relies on various
protocols (a set of rules) to
facilitate communication and data
transfer. The most fundamental
protocol is TCP/IP (Transmission
Control Protocol/Internet
Protocol), which breaks data into
packets, ensures their reliable
delivery, and manages addressing.
DNS (DOMAIN NAME SYSTEM)
• When you enter a web address
(e.g., www.example.com) in your
browser, DNS servers translate this
human-readable domain name into
an IP address, allowing your device
to locate the server hosting the
website.

INTERNET EXCHANGE POINTS (IXPS)
• These are physical locations where
Internet Service Providers (ISPs)
and other network operators
connect their networks to
exchange traffic. IXPs play a vital
role in efficient data routing.
INTERNET SERVICE PROVIDERS (ISPS)
• ISPs are companies that provide
individuals and businesses with
access to the Internet. They
connect their networks to the
broader Internet and ensure data
can flow between your device and
the rest of the world.

9. EXAMPLES OF IOT

DATA CENTERS
• Large facilities housing numerous
servers and networking
equipment. They store and manage
vast amounts of data, ensuring
redundancy and backup for reliable
service.
SECURITY PROTOCOLS
• To protect data as it travels over
the Internet, security protocols like
SSL/TLS (Secure Sockets
Layer/Transport Layer Security) are
used, especially for secure
transactions and data transfers
(e.g., HTTPS for secure web
browsing).

10. SUMMARY
10
In summary, the Internet works as a vast interconnected web
of devices, transmission media, protocols, and data centers.
Data is broken into packets, routed through routers, and
transmitted using various media, with protocols ensuring
reliable communication. DNS translates domain names into
IP addresses, ISPs provide access, and data centers store and
manage information. This intricate system allows us to access
and share information globally, powering the digital age.
