How the server works
If we give answer to how the server works in computer language then it will become very complicated, I will give you a simple example of how the server works. You can read below how the server works.
When a user has to open a web page, he types the link to that web page in his browser and then searches. Then that web page starts appearing in front of him. This is how an ordinary people knows how the server works, but it does not happen. In just a few seconds, the server goes through several processes, then it goes and shows the web page to the user.
As you write www.google.com in your browser and then press Enter, then your request goes to DNS (Domain Name Server) that a user wants to see this web page. Then that DNS provides Google’s IP (Internet Protocol) to your browser. All the web pages you see on the internet are open only through DNS.
Every web page has three types of IP Address that are already added to DNS. After that, the IP address that web page gives to your browser, the browser matches it with your server, which web page is this IP address. When your browser finds the IP address of that web page in its database, it displays that web page in front of you. All the web pages present in the Internet world are open only after getting the right IP address.
How the server is down
You must have heard that the server is down, the website is not opening yet. We often get to hear this when we go to the bank or our or someone else’s online result is coming. At that time, the website on which our result is going to come, sometimes it happens that we are not able to open that website. The reason for this may be the weakness of your network, but most of the time it is not.
When we open that website, our browser instead of opening that web page, it writes Server is Busy, Server is Not Found etc. We see this, we should understand that the server with which this website is hosted Is she is busy now. Never before had people come together on this server or website, but today many people have opened this website. All servers are different, how much of a user’s device they can open that web page at a time, it is determined by their server.
When a website connects with a low capacity server, it is unable to open that web page in more people’s devices. Now you will say that whether the website of the bank is also hosted on a low capacity server, the answer can be yes or no. Google is also a website which is visited by millions of people every second, but its server is not down, but the answer is how the server of these bank is down.
That his website connects with low capacity servers. It takes more money to connect with a server with more capacity. This is the reason that the server is down.
