1. Introduction to the Internet

2. What is the Internet?
 Definition: The Internet is a global network of interconnected computers
that communicate using a standardized protocol suite called TCP/IP.
 Origin: Developed in the late 1960s as ARPANET by the United States
Department of Defense.

 Protocols: Standardized rules and procedures governing data exchange
(e.g., TCP/IP, HTTP, FTP).
 Services: Applications and platforms that utilize the Internet, including
websites, email, social media, and online gaming.

4. How Does the Internet Work?
 Data Transmission: Information is broken into packets, transmitted via
routers, and reassembled at the destination.
 Connectivity: Devices connect to the Internet through Internet Service
Providers (ISPs) via wired or wireless connections.
 Addressing: Each device on the Internet is assigned a unique IP address for
identification and communication.

5. Types of Internet Connections
 Dial-Up: Uses a telephone line to connect to the Internet. Slow and
outdated.
 Broadband: High-speed internet access provided through various
technologies like DSL, cable, fiber-optic, and satellite.
 Mobile: Internet access through cellular networks using smartphones,
tablets, or mobile hotspots.

accessed via the Internet.
 Email: Electronic mail service for sending and receiving messages over the
Internet.
 Social Media: Platforms for online networking, sharing content, and
interacting with others.
 Online Shopping: E-commerce websites for purchasing goods and services
over the Internet.

7. Internet Security
 Cybersecurity Threats: Malware, phishing, hacking, identity theft, and data
breaches.
 Security Measures: Antivirus software, firewalls, encryption, strong
passwords, and regular software updates.
 Privacy Concerns: Data collection, tracking, and online surveillance by
companies and governments.

8. Conclusion
