why do server crashes happen and What is the server
What is the server.

In this article, you will learn about what a server is, how it works, why the server is disabled, and what types of servers are. So let's start this article without taking too much of your time.

What is a server

If I tell you about the server directly in a technical language, then probably not all readers who read this blog will be able to understand it well, so to understand the server in easy words, understand it by a realistic example.

Let's say you went to a hotel or restaurant. And order the food of your choice there. Then the waiters who work at the hotel go to their store and offer you the food of your choice. So the waiters in this way are somehow hotel servers who serve food to customers according to their requests.

Now in this example :

  • We are hotel customers who are looking for information on the internet.
  • Hotel waiters are servers who provide us with service.
  • The store is the data center, where all information is saved.

Likewise, it happens that in the online world, whenever we search for some information on the internet, we need someone who can serve us all this. On the internet, this work is performed by the server. Servers are high-quality computers.

Servers are high-power computers. These programs are installed in the computers that provide the service. Such high-power computers are called servers.

Definition of Server

On the internet, where there is a huge stock of information, the medium that serves this information to the user is called the server.

How the server works

Now you should have understood what a server is, now you know how to do this work.

When you search for anything on Google, YouTube, or any other search engine, the server brings you information related to the query you are looking for within seconds. The Working Mechanism of the server is as follows:

When searching the query, the servers go to the data center with your request. Then from there, we show you the information related to your query.

Just like you watch a video on YouTube, this video is stored in the YouTube data center and when you search for this video, the YouTube server fetches this video from its data center.

Likewise, we also see the photos that we posted on Facebook many years ago. This image of us is saved in the Facebook data center and when we click on the image to view it, the Facebook server shows us that image.

Why server crash

You must have seen or heard on any website or government bank that the server is down today. So the question now is what server is down and why is it down.

I showed you above by the example of a hotel, now assume that thousands of people suddenly came to this hotel. So now that the number of employees working there is constant because more people are coming, the work system there will be disrupted. It will take a long time to service the order.

Just as it happens in the online world, in the online world too, all servers have a certain capacity for how much traffic they can handle. That is, it is the number of people who can simultaneously visit this site.

When suddenly a million traffic comes to this website, or if the traffic to this website is more than the server capacity of this website, the server will load. Due to the load in the server, either the site takes a long time to open or the server fails. We only call the server when the server fails.

Server types

There are many types of servers, but I will give you information about some important servers.

1 – webserver

The web server makes the data service of all sites on the internet. When a user searches for some query in his browser, the web server takes his request and goes to his data center, and presents the data of that location in the user's browser.

2 – mail server

The mail server serves all the emails we do.

3 – audio/video server

An audio/video server is a server that serves all audio and video files that are on the internet.

4 – file server

This server is used to transfer files from one place to another.

5 – chat server

The mission of the chat server is to serve all the chats that we do in the online world. With the help of the chat server, we can do many things very easily today.

6 – FTP Server (File Transfer Protocol)

This is a very old server that uses an FTP server for the secure exchange of files on the internet.

7 – proxy server

It is an intermediary server. It connects the user's request to the internet indirectly and transmits information from there to the user.

When a user searches for something on the internet, through the internet user's IP address, he knows to whom this information is given. Now if the user uses a proxy server, the proxy server takes your request and goes to the internet.

Here the proxy server hides the identity of the user from the internet. That is, the user's IP address hides the site. It takes information from the internet and gives it to the user. Because the internet does not know to whom this information is given. Uses proxy server for security.

What are a dedicated server and an unallocated server

Because the server is only one computer. You can also install the program on your computer and make it a server. If you don't stay connected to the internet for 24 hours on your server, that server is called an unallocated server. Such as servers used in schools and offices.

Servers connected to the 24-hour internet are called Dedicated Servers. Like Google, YouTube, and web servers. They are expensive because they are high-power computers. Storage, RAM, and processor are all very high quality.
