Before I give the exact definition of a server, I want to explain it with an example. Let’s compare your personal home with a store. There may be one or two bottles of juice in your private home.
But there are several shelves of fruit juice in one store. In fact, I want to say that any food that is limited in your home is definitely available in a store with a much higher volume.
In the example I gave, your personal home is exactly the same as your personal computer or mobile phone. And the store is exactly the same server.
A server is just like having multiple computers running and serving the body at the same time. That is, it gives the user several times more powerful and complete features than a personal computer.
There are two differences with a personal computer. First, it can support a much larger number of users simultaneously than PCs.
Second, unlike a computer or personal phone whose information is accessible only to you, access to that information is available to everyone.
Now each server can be divided into several different parts and each of these parts forms a storage space.
These sections are called hosts. Host is where you store your site information and files.
To put it more scientifically, a server is a computer program that provides a service to another computer program and its user, also known as a client. This device can be a dedicated server, or it can be used for other purposes.
The web server can work with both hardware and software, or both. As a hardware, a web server is a computer that stores web server software and website component files. It also connects to the Internet and supports the exchange of physical data with other devices connected to the Web.
On the other hand, as software, a web server consists of several parts that control the access of web users to hosting files.
Servers are often categorized by purpose. For example, we can mention the following: Web server, which is a computer program that serves the requested HTML pages or files. In this case, a web browser acts like a client.
An application server is an application on a computer in a distributed network that provides business logic for an application.
A software proxy server that acts as an intermediary between the destination device, such as a computer, and another server that the user or client requests service from.
A virtual server is a program that runs on a shared server and is configured in such a way that each user seems to have complete control over the server.
