What is a Server and How Do it Work

What is a Server and How Do it Work

Server

The server or what is termed a server is a computer with very high capabilities that is evident in its ability to meet the desires and requests of many computers across the world. Of course, what this feature gives it is its ability to process, i.e. data processing, as well as Internet connection, which is very, very fast.

In other words, a server or server is a computer device that has the ability to endure working conditions continuously and for long periods. The provider can be linked to various types of networks, for example:

Internal networks that do not operate on the Internet

The server, as indicated by its name (the server), serves and performs the task of serving and providing the devices connected to it with the various data they want, in addition to that it performs the task of storage and archiving.

Multiple computers connected to the server

In order to perform these operations, it contains very large storage areas in addition to a multi-core CPU. It should be noted that any computer can be used as a server provided that it has strong specifications, especially with regard to CPU and storage space.

 It should be noted that the server needs several requirements in order for it to perform its work in the best way, and among these requirements necessary for the work of the server we mention the following:

- A permanent power source: that is, the server must be provided with an electrical current continuously because it works without stopping 24 hours on 24 hours for long periods that may reach many years depending on the type of server, and the reason that the provider must work continuously is that stopping it, even for a moment, will make all the sites hosted on it It stops working.

The server also needs cooling systems with very high efficiency because, as we said, it works constantly, which will make its electronic components overheat abnormally and therefore need constant cooling as well in order to work in good performance.

2- The role of the server

The server is the main incubator for Sites, and therefore it provides site visitors with all the data they are looking for. So it plays the role of providing users with data, as well as the task of archiving and saving topics on a specific site.

3- How the server works

Below I will present to you how the server works on the Internet:

When someone puts a specific link for the purpose of viewing the topic it contains, and while pressing the search button, the browser, for example, Google Chrome, contacts another server called the DNS server, short for Domain Name System. After connecting to this server, it finds the IP accompanying the server hosting the website to which the link the user searched for and sends it to the browser so that there is a direct connection between the browser and the server and thus the user is provided with the link data from the server towards the browser used.

For reference, the website hosting server deals with thousands of users at the same time, which means that it is characterized by a very large Internet connection speed.

4- Server components

The server or server consists of several things, namely:

Hardware or Hardware

They are the tangible physical elements of the device, for example: the processor, random access memory or the so-called RAM, units of both storage and power supply in addition to the communication card or network, BIOS and other components.

Server OS

Of course, the operating system does not need to be explained because it is just like the normal Windows operating system for a computer in terms of the basics with minor changes, and this system is called Windows Server.

Server programs and applications

Of course, they are applications that are used to complete server tasks

5- Types of servers

Of course, there are many types of servers, knowing that one server may play more than one role. From the types of servers we mention the following:

Web server

The Web Server is the server hosting websites that holds all of their data.

Email Server

Mail Server is the provider that is primarily responsible for email messages and their storage.

Database server

Database Server is a provider specialized in saving and managing data, which contains very large storage space for that called a database server. It should be noted that this server provides data to the rest of the other servers.

DNS server

A DNS Server is a provider that has the role of translating domain names into IP addresses or the so-called Internet protocols, and this is what we talked about earlier. So, it is a helper server.
