What Is a Server Definition? What Are the Types of Servers?
All businesses have a server for their business. It plays an important role but most people don’t know what it is exactly and how it works. To get the most out of it, store and access data easily across your network, you should know how to set it up correctly. In this guide, we are going to provide some useful information. So, stay tuned!
What Is a Server?
At the beginning of this article, we must answer the question: what does a server do. It must be pointed out that, the server is a powerful computer that is always working from which users expect responses to their requests at different times. When access is limited to an internal network, it is called a network server. That is, all the computers on this network receive a command from the server and support their network needs with its help.
Now if you look at the scope of this network a little bit wider and consisting of all the computers that are connected to the Internet, we are facing a very large group of computers always working and accessible via the internet. Internet servers provide users with information that is searched at any time of the day on the Internet. Now that you are more familiar with the concept of the server, throughout the article, we will focus on server hardware.
Types of Server Hardware
If we want to offer a server hardware definition, we should say that the server consists of specific hardware components that are expected to deliver the highest processing and performance. Generally, servers consist of a powerful processor with multiple physical and virtual cores, a high RAM, and multi-terabytes of hard disk storage. Given this amount of power and performance, the server should be kept in a space that can work and be connected to the internet 24 hours without interruption. Server usage makes sense with this structure and responds to multiple user requests.

What Is a Datacenter?
On the Internet, one of the most important factors when receiving a service is server stability. Special locations around the world called Data Center, are being built to maintain servers and their focus is on network quality, component support, and software requirements. These Data centers specifically provide conditions to use servers without any interruptions and other problems. So Data-center is the place to store hundreds or thousands of servers in different racks, cages, and rooms. The Data-center building consists of various parts such as the control room, server room, generators, cooling facilities, hardware warehouse, UPS room and Battery Backup, fire extinguisher storage room, and network management room. These sectors will be completely different depending on the needs, design, facilities, and infrastructure for each data center.
Server Operating System
Different operating systems can be installed on the server. Here’s a look at what these server-side operating systems are and what they have in common. The operating system is installed depending on the type of software that will be installed on the server. We suggest you read our article “What is Windows Server?”
Server Operating System Classification
- Linux: All Linux distributions like CentOS, Debian and etc.
- Windows: All different versions of Windows such as Windows Server 2012, Windows Server 2016, or older versions of 2008
- Virtualization: Virtualization software like KVM, Hyper-V, Vmware ESX, and more

What Are Server Features?
- The exclusivity of hardware resources
- Ability to upgrade and improve server hardware
- Permanent Internet connection
- Very high-performance speed
- Processing power and fast computing power
- High security
- Ability to implement software and hardware raid on the server
Server Types in Terms of Resource Allocation
So now that we are familiar with the meaning of ‘What is a server’, now we will be exploring server usages. Servers are divided into several categories, namely, shared servers, Virtual Dedicated Servers (VDS), and Dedicated Servers, which differ in how their resources are allocated.
Shared servers are defined by the type of their application which includes a number of websites, databases, or email domains that respond to multiple requests from users at one moment. As you can tell by the name of a shared server, its resources, including CPU, bandwidth, storage space, and so on, are shared between users according to the server administrator’s definitions.
Virtual Dedicated Server
A larger scale with dedicated resources of a shared service, in which through “virtualizing“, resource allocations of a Dedicated Server hosting is divided into several virtual machines. Given the proprietary nature of virtual machine resources, the number of websites created on the host server will be less than shared server websites.
Large companies and frequently visited websites like online shops will require more resources than one virtual machine. Users of these services are served with a completely dedicated RAM processor, data storage space, rack location, and bandwidth on a single server.
What Are the Types of Servers?
Depending on the usage of the servers, there are different types of server OS (Operating System) with various performances, some of which are mentioned as follows:
1- Web Server
This type of server is used for setting up websites and hosting.
For more detailed information on what is a web server please read the source of our article.
2- Mail Server
Uses a mail server to send and receive emails. It can be used for email services by installing email software like Smartermail, Postfix and, etc. on the server.
3- Database Server
This type of configuration is often used by organizations or companies as software or service for a database.
4- Application Server
The software used by server users is installed on this server and the user can access it through their computers.

5- File Server
File server one of the most basic and easiest servers to share files with.
6- DNS Server
The server on which the DNS Web Services and Services are hosted, and has the task of resolving the IP addresses of the web server, email server, etc. on the Internet.
7- Game Server
The game server is a type of Application Server that will only be used for games. The game is installed on the server and users connected to the network can use the game by interacting with the game server.
8- Media server
Media server is used for sharing multimedia services or Media.
9- Proxy Server
As an interface between the main server and the client, it receives information from the parties and sends it to the recipient after review.
Frequently Asked Questions
1) What Do You Mean by Server?
A server is a computer or system which provides data, resources, programs, and services to other computers that are usually called clients. A server can provide resources for clients and at the same time can use resources, which means play a role as a client.
When choosing the right server, there are a few things to keep in mind. Hardware configuration, powerful network infrastructure and Internet, security capabilities, and data protection are all things we need to pay particular attention to. Another important point is the use of the server and that the server is designed to meet what needs and resources. Before selecting a server, evaluate its specific features to provide a cost-effective, practical server. For more information click here .
