What is the Internet?

The Internet is a global network that connects millions of computers and devices, allowing them to share information. It works by linking computers through cables, satellites, and wireless signals so they can communicate with each other.

For instance, when you browse websites, stream videos, or send emails, your device connects to the Internet to share and receive data quickly.

How Does the Internet Work?

The Internet works by breaking data into small pieces called “packets.” These packets travel between devices using a network of cables, satellites, and wireless signals. It is like sending letters through a postal system, but it is much faster.

Main Components of the Internet

Servers: Powerful computers where websites and online content are stored.
Clients: Devices like phones, tablets, or computers that request information from servers.
ISP (Internet Service Provider): Companies that connect your device to the Internet, such as AT&T, Verizon, or Comcast.

Example of How the Internet Works

When you search for “cute cat videos” on your phone, here’s what happens:

Your phone sends a request (as data packets) to a server through your ISP.
The server finds your desired videos and sends the data packets back to your phone.
These packets reassemble on your screen, and voila! Cute cat videos start playing.
