How the internet works

The internet is a vast network of interconnected computers and servers that enables devices around the world to communicate with each other and access and share data and resources. It works by allowing devices to send requests for information or resources to servers through an internet service provider (ISP). When a device sends a request, it is transmitted via a physical connection (such as a cable or wireless signal) to an ISP’s server, which is connected to the internet. The ISP’s server then sends the request to the appropriate web server through the internet, using a unique address called an Internet Protocol (IP) address. The web server retrieves the requested information or resource and sends it back to the ISP’s server, which then sends it to the requesting device. This process happens quickly, allowing users to access and interact with information and resources on the internet in real-time.

Here’s a brief overview of how the internet works:

• A device, such as a computer, smartphone, or smart TV, connects to the internet through an internet service provider (ISP). The ISP provides a connection to the internet via a wired or wireless connection, such as a cable or DSL line, or a cellular network.
• The device sends a request for information, such as a webpage, to a server. This request is sent via a protocol called Transmission Control Protocol (TCP).
• The server receives the request and sends back the requested information, such as the HTML code for a webpage, via another protocol called the Internet Protocol (IP).
• The device receives the information and interprets it using a web browser, which renders the webpage on the device’s display.
• The device can also send and receive data through other internet protocols, such as email, instant messaging, and file transfer, allowing people to communicate and access information online.

Overall, the internet is a vast network of interconnected devices that allow people to communicate and access information from anywhere in the world.
