Key Parts That Make the Internet Work
In order to learn how does internet work, you need to know about its basic components.
Modem
A modem is the hardware that supplies internet signals from your internet service provider (ISP) inside your home. It converts signals into data that your device can comprehend.
Router
That is then sent from the router to your phone, computer, or smart TV. It works like a traffic cop to direct each packet accordingly.
IP Address
Each device has its unique number known as IP address. Similar to your home address but for your computer.
DNS (Domain Name System)
It is DNS (Domain Name System) that translates website names like google. com” into IP addresses. This does wonders for computers because it allows them to know exactly what servers to locate.
Server
A server is a computer that has a lot of data, such as websites, videos, etc. So every time you click on a link, your device communicates with a server.
Comparison Table: Modem vs Router vs Server
| Component | Function | Role in the Internet |
|---|---|---|
| Modem | Connects home to internet | First step in data flow |
| Router | Shares internet to devices | Directs traffic in your home |
| Server | Stores and sends content | Final stop before content reaches you |
Wired vs Wireless Internet
The internet can reach you in two main ways: through wires or without them.
Wired Internet
Wired internet uses cables to deliver strong, fast connections. It’s common in offices and homes where speed matters.
Wireless Internet (Wi-Fi)
Wi-Fi lets you connect without cables. It’s very flexible and used almost everywhere—homes, cafes, schools.
| Type | Speed | Stability | Usage Area |
| Wired | Faster | Very Stable | Homes, Offices |
| Wireless | Slightly Slower | Less Stable | Public areas, homes |

- Around 99% of internet traffic takes place over underwater cables.
- Every second, there are more than 99,000 Google search queries.
How the Internet Works Through Fiber Optic Cables
As the name suggests, fiber optic cables transmit data in the form of light. The internet, in its entirety, has never been used this quickly or securely before. Light signals representing data pass through tiny strands of glass within the cable.
These are cables that are laid under oceans and land. They are part of the internet backbone, which facilitates data transfers between nations, in a matter of milliseconds.
How are websites appearing instantly (when you type url in browser address bar)?
For instance, if you enter a website like www. Wikipedia. When you type in something like google. It first locates the website’s IP address then taps the server the website resides on. Packets Get Back To Us From The Server Your device assembles it to present the site to you.
