At its most basic level, the internet is a global system of interconnected computer networks that use standardized communication protocols to exchange data. But what happens when you type a web address into your browser or send an instant message to a friend across the world?
The process begins with your device—be it a computer, smartphone, or tablet—connecting to an ISP, which acts as your gateway to the wider internet. Most ISPs use a combination of fiber optic cables, copper wires, wireless towers, and satellites to route data between users and servers.
The Domain Name System (DNS) translates human-readable web addresses (like www.example.com) into IP addresses, which computers use to identify each other on the network. When you request a website, your device sends a query to a DNS server, which returns the corresponding IP address, allowing your browser to connect to the correct server.
Data travels in small packets, each containing a portion of the information you requested. These packets may take different routes across the internet’s vast network of routers and switches before being reassembled at their destination. The TCP/IP protocol manages this process, ensuring that packets arrive intact and in the right order.
Websites and online applications rely on servers—powerful computers that store and deliver content to users. Application Programming Interfaces (APIs) are essential for enabling communication between different software systems. For example, when a website displays real-time weather data or social media feeds, it likely uses APIs to retrieve that information from other services.
