What Is the Internet?
A global network of connected computers forms the internet. These computers communicate with each other using Internet Protocol (IP). The internet allows smartphones, laptops, and servers to share information over long distances.
Think of the internet as a giant web. Nodes in this web represent computers and devices, and threads represent their connections. These threads allow data to move smoothly between devices, providing us with a seamless experience.
The journey of your data
When you type a URL into your browser and press Enter, your data travels from your browser to the server through these steps:
DNS resolution: The browser looks up the IP address for the domain in the URL. The Domain Name System (DNS) maps domain names to IP addresses.
TCP connection: The browser initiates a TCP connection with the server.
HTTP request: The browser sends an HTTP request to the server. The request includes the resource being requested, headers, and sometimes query parameters.
Server processing: The server processes the request and generates an HTTP response. The response includes:
An HTTP status code that indicates whether the request was successful, redirected, or if there was an error
HTTP headers that provide additional information about the response
The response body, which contains the content of the requested page
Browser rendering: The browser renders the content.
The TCP/IP protocol transmits the data between the browser and the server.
The World Wide Web (WWW) allows users to access and share information over the internet. It uses a client-server model, where a user's device (the client) sends a request to a server, which then sends back the requested information.
We collectively know all public websites or web pages that people may access on their local computers and other devices through the internet as the World Wide Web or W3. Users can get further information by navigating links that interconnect these pages and documents. The internet may present this data in text, picture, audio, or video formats.
What is WWW?
The WWW, or World Wide Web, collects websites from around the world, each sharing different information through local servers or computers. Hyperlinks, also known as hypertext, link web pages together and are HTML-formatted. These are the fundamental units of the Internet and are accessed through Hypertext Transfer Protocol (HTTP). These digital connections, or links, let users easily find the information they want by connecting related pieces of content. Hypertext allows you to select a word or phrase and click on other sites that provide more information about it.
What is an IP Address?
An IP address, or Internet Protocol address, uniquely identifies each device connected to a computer network that uses the Internet Protocol for communication. It allows devices to send and receive data over the network, ensuring that this data reaches the correct destination.
