In the answer , the server in Farsi is mentioned as the server. What does the question server mean? It must be said, it is a computer that is always on and powerful, from which users expect answers to their requests at different times. The history of servers has been recorded since 1981
When
access to the server is only within an internal network, it is called a network server. This means that all the computers in this network receive commands from the server and meet their network needs with its help.
Now, if we consider the scope of this network a little more and made up of all the computers that are connected through the Internet, we are facing a very large group of computers that are always on and accessible through the Internet. Internet servers provide users with the information that is searched on the Internet at any time of the day or night.
For example, as you know, there are different browsers such as Chrome, Mozilla Firefox, Opera, etc. that you can use. When you are looking for a topic in your browser (for example, Chrome browser), in this case you give your request to the browser and this browser goes to the relevant server and takes the necessary information and data from it and delivers it to you. to give
Servers have their own software and operating systems that are installed on these computers. Among these server operating systems, we can refer to the operating systems of various Linux and Windows Server distributions. Also, based on the structure, when buying a dedicated server in Iran and abroad, you should know that the servers are divided into three categories: Tower, Rack and Blade, and Rack and Blade are mostly used in large environments and networks such as ISPs. These servers must work around the clock. For this reason, the best methods are used to care for and cool them. For this reason, when installing the server operating system, you should pay attention to the use of the server and the software installed on it. Windows Server is an example that can be mentioned here. And we suggest you, if you want to get more information in this regard, refer to the article What is Windows Server.
As you know
, the server is a powerful and always-on computer that consists of a series of hardware and software resources and needs settings and maintenance. In fact, by implementing appropriate settings for the server, you can somehow architect its structure and make better use of its resources. In other words, by using the server settings, we determine how to communicate and the user's access to the server's resources. Here are some examples of how to set up a server:
The easiest way to set up a server is to put all its resources, including the software program, database, etc., in one environment. In this method, which can be implemented quickly, the user has a direct connection with the server. Of course, troubleshooting this type of setting is a bit difficult.
It is possible to separate the database from the Internet and connect the user to it through a server program. Doing this increases the security and protection of the database. On the other hand, if there is no bandwidth and other suitable conditions for communicating between the database server and the application server, it will cause poor performance.
Another type of server configuration is using a load balancer. This method will be suitable if you want to offer several applications on the same domain. Of course, if the load balancer, which is the interface between the user and the main server environment, does not work, the performance of the application and the provision of services will be disrupted.
Database replication is another method. The structure of this method is very similar to the previous method (load balancer). With the difference that for each server, a readable database is replicated. Updating the database (writing) is done through the server designated as Master, and it is possible to read for other servers. Therefore, the database update is delayed due to failure of the Master server.
According to the use of servers, there are different types of servers with different performance, some of which are named as follows:
This type of server is used to set up websites and hosting. The article What is a web server can give you more information in this regard, which is beyond the scope of this article.
Email server is used to send and receive emails. By installing email software such as Smartermail, Postfix, etc. on the server, it can be used for email services.
This type of configuration is often used in organizations, companies for the database used by a software or service.
An ad hoc network occurs when two or more computers are connected through an intermediary node. First, ad hoc network does not need basic infrastructure such as routers or access points. Secondly, an ad hoc network is a temporary wireless network. In any place where there is no internet and people need to share their files, ad hoc network...

Suppose you are going to set up a computer network. A computer has a port or network card and a place to connect to another system. What if you have several computers in your company or complex that are supposed to communicate with each other? You can communicate with only one other computer from one system. To communicate with several systems, it is necessary to.....
