How Servers Work

how server work

The question now is, how does server work? In simple terms, the server works at the request of a client. For example, in the case of a web server, when you type a website address using a browser, it means that your computer is acting as a client requesting information from the web server. The web server then sends the contents of the website to your computer, so that you can access the website content.

For other cases, such as an FTP server, it may be a little different. On an FTP server, you can upload a document or data to an FTP server, so that it can be stored on that server. As a client, you have the right to store your data on an FTP server. Later, if there are other people who are members of the server network and want to download your data or documents, the FTP server will provide a connection for these other clients.

In general, all types of servers work by carrying out the functions previously mentioned, from serving data requests from clients to providing protection to client computers. It’s just that, for different types of servers, the things served are different.

A device that is used as a server generally has a different design, when compared to a client computer. For example, in terms of device specifications and operating systems. The computer equipment used as a server must be equipped with high specifications. The reason is none other than because the server computer has to handle large data traffic.
