Maybe many people don’t know what a server is. But surely it is no stranger to computer lovers. It’s generally hard for us to see the real server. Because servers are generally located in hidden points of computer rooms. So, speaking of servers, there are still a lot of friends who are not familiar.

In a technical sense, a server is an example of a computer program or device that processes requests and sends data to other computers via the Internet or a local network. Servers are used to manage network resources. For example, a user can set up a server to control access to Web access, send/receive email, manage print jobs, or host a website.

In this article, digeststory will introduce you to what is a server? What are the most common types of servers used? and what are the functions of the server? So that everyone has a simple understanding of the server, We hope to be able to help you.

What is a Server?


In a technical sense, a server is an example of a computer program or device (basically a type of computer) that processes requests and sends data to other computers over the Internet or local networks.

Computers that provide services to users in a networked or distributed processing environment. It can be divided into access server, file server, database server, communication server and application server.

The actual server is the same as a normal computer. But it has stronger stability, security and data processing. Generally our personal computer can also be a server, and we only need to install a server system. But servers have high requirements for hardware stability and quality.


What Are Servers Used For?


Servers are used to manage network resources. For example, users can set up servers to control access to the network, send/receive email, manage print jobs, or host websites. They are also good at doing intense calculations. Also read 10 Software For Monitoring Network Servers And The Best Applications.

Some servers are also dedicated to a specific task, often called a dedicated task. However, many servers today are shared servers, and in the case of web servers, they can be responsible for email, DNS, FTP, or even multiple websites.

Server Specific Features And Functions

Almost any personal computer can act as a web server. Oftentimes, however, specialized computer systems software or hardware have features and configurations that are only used for this task.

For example, a dedicated server might have high-performance RAM, a faster processor, and multiple high-capacity hard drives. In addition, dedicated servers can be connected to redundant power supplies, multiple networks and other servers.

What is a Server

These connection features and configurations are necessary because many client machines and client programs may depend on them to function efficiently, correctly, and reliably.

To operate in a unique network environment where many computers and hardware or software systems rely on only one or more server computers. Servers often have special features and functions, including:

Ability to update hardware and software without rebooting.
Advanced backup function, which can back up key data frequently.
Advanced network performance.
Automatic data transfer (invisible to the user) between devices.
Highly secure resource, data and memory protection.
What Are the Most Commonly Used Server Types
A computer may require many services to work. Therefore, there are different types of servers available. What types of servers are commonly used today?

1. Web Server

The web server displays the page and runs the application through a web browser. The server our browser is now connecting to is the web server that serves this page and any images you see on it. Also read the Most Recommended Web Server Software To Use.

In this case, the client program is most likely a browser such as Internet Explorer, Chrome, Firefox, Opera or Safari. Apart from serving simple text and images, web servers can be used for many things. Such as uploading and backing up files online via cloud storage services or online backup services.

2. Email Servers

Email servers facilitate sending and receiving emails. If we have an email client on our computer, the software will connect to an IMAP or POP email server to download email to your computer, and an SMTP server to send email back through the email server.

3. FTP Server

What is a Server
FTP Server supports file transfer via file transfer protocol tools. The FTP server can be accessed remotely via an FTP client program.

4. Identity Server

Identity Server supports login and security roles for authorized users.

Why Servers Keep Running?
Since servers are usually used to provide services that are always needed, most servers are never shut down. Therefore, when servers fail or are in a state of trouble they can cause a lot of problems for web users and companies. To mitigate this problem, servers are often set up to be fault tolerant.

The computer or computer system running the above software is also referred to as a server. Compared to ordinary PCs, servers have higher stability, security and performance requirements. So that hardware such as CPU, chipset, memory, system disk, network, etc. is different from ordinary computers, in terms of quality and better processor data performance.

The difference between a server and an ordinary computer is not only a difference in hardware performance indicators, but also a system difference. Our computers generally use
