Defining the Internet

The Internet is a global network that connects computers and devices worldwide.
It facilitates communication, information sharing, and various online services.

Global Internet Reach

Approximately 4.7 billion people globally have access to the Internet.

Impact of Mobile Applications

Mobile applications have significantly increased Internet usage and accessibility.
They provide a convenient platform for accessing online services and information on mobile devices.

Key Technology Concepts of the Internet

The Internet relies on a combination of hardware and software technologies.
Key components include:
- Client-server architecture: Clients request services from servers.
- TCP/IP protocol suite: A set of communication protocols that govern how data is transmitted and received across the Internet.
- Packet switching: Data is divided into packets and sent over the network.

Internet Services

The Internet offers a wide range of services, including:
- Communication: Email, instant messaging, video conferencing.
- Information access: Search engines, web browsing, online databases.
- E-commerce: Online shopping, financial transactions.
- Entertainment: Streaming services, online gaming.

Network Architecture

The Internet is a packet-switched network.
It uses TCP/IP for communication, similar to the telephone system.

TCP/IP Architecture

The Network Layer of the TCP/IP architecture is responsible for addressing, packaging, and routing messages.

Packet Assembly and Reassembly

TCP (Transmission Control Protocol) in the TCP/IP protocol suite handles packet assembly and reassembly.
It ensures that data is sent and received in the correct order.

Location Identification

Uniform Resource Locators (URLs) are used by web browsers to identify the location of content on the web.

Client-Server Computing

Client-server computing involves a network of client computers connected to a central server.
Clients request services from the server.
