How does the Internet work?

Today in this article we will try to give you a brief understanding of the internet.

The Internet is a network of computers that are spread worldwide. These computers talk to each other in a common language so that they can understand each other. In this way, information is sent or received from one computer to another computer.

There are two things you need to know about, that is, TCP and IP. TCP and IP work together to ensure that data transmission across the internet is consistent and reliable, no matter which device you’re using or where you’re using it.

When data is transferred over the internet, it’s delivered in messages and packets. Data sent over the internet is called a message, but before messages get sent, they’re broken up into tinier parts called packets. These messages and packets travel from one source to the next using Internet Protocol (IP) and Transport Control Protocol (TCP). IP is a system of rules that govern how information is sent from one computer to another computer over an internet connection.

What physical infrastructure makes the Internet work?

A lot of different kinds of hardware and infrastructure go into making the Internet work for everyone. Some of the most important types include the following:

  • Routers forward packets to different computer networks based on their destination. Routers are like the traffic cops of the Internet, making sure that Internet traffic goes to the right networks.
  • Switches connect devices that share a single network. They use packet switching to forward packets to the correct devices. They also receive outbound packets from those devices and pass them along to the right destination.
  • Web servers are specialized high-powered computers that store and serve content (webpages, images, videos) to users, in addition to hosting applications and databases. Servers also respond to DNS queries and perform other important tasks to keep the Internet up and running. Most servers are kept in large data centers, which are located throughout the world.
