We use the World Wide Web as an example of one online application to explain how the internet functions. Any website that we visit daily is the application. The browser begins speaking with the DNS server when you visit the website or type its name into the browser.
Every website is assigned a unique IP address by the DNS server, which is only a computer (physical server location). Only binary digits are understood by the computers; no words or phrases are. The DNS keeps a list of all websites' IP addresses. The query is forwarded to the server once it maps the website's name to its IP address.
On the internet, each machine has a unique IP address. The DNS server points to the original server where the information pertaining to the website you typed is stored once you enter the website's name into the browser. The originating server then answers to your request and transmits the data you asked for.
All of this actually takes place within a vast computer network. The DNS server plays a crucial role in locating the web server. If it doesn't have the required information, it also passes the inquiry to other DNS servers. This continues until eventually one of the DNS servers correctly identifies the primary server.
The website then shows up on your screen. Simply said, it takes place in a split second. One of the internet's applications is this. Even though there are literally millions of services and applications available online, the internet is expanding daily.
