types of servers

In the field of computer science and telecommunications, server means “a computer equipment that is part of a network and provides services to other equipment.” There are many types of server according to their function and content, every day, as with all the elements that continue to play a decisive role in the technological and Internet landscape. These are some of the most common types of servers that we can find in the market:

Different Types of servers:

Web servers:

Web servers, also known as HTTP servers, arise in 1990 due to the need to standardize communication between different platforms and programming languages, providing an alternative for faster and easier exchange of information.

These provide the necessary tools to store all the information contained in a web page, and also send the information to the client that requests it, that is, they make possible what is known as hosting .

A Web server has the ability to simultaneously respond to requests from several computers; However, its efficiency may depend on factors such as processing speed, hardware, number of requests, and dynamic web content, since the latter require a greater amount of resources than static content.

Among the web server options you can find, the most common are shared servers, dedicated servers, and virtual servers. Shared servers offer a space for you to host your information, and you must share resources such as the same CPU, RAM, operating system, IP address, and even the same internet connection.

A dedicated server is one that hires a single client, which should not share resources with anyone else, and the storage capacity it offers is superior to any other type of web hosting. Finally, the virtual server is the one that combines characteristics of the previous two; The physical server performs virtual partitions that work independently, and the only thing that is shared is the cost.

In the article What is hosting and what is it for? , you can find more information about the different hosting options that exist.

FTP servers:

A File Transfer Protocol server, or File Transfer Protocol for its acronym in English, is a program that runs when connected to the Internet or some other type of network (LAN, MAN, etc.), which allows the displacement or transfer of data between other servers or computers.

These types of servers were created based on a client-server architecture, that is, the client’s computer must first connect to the server in order to download or store files.

Although it is one of the oldest protocols, since its creation dates back to 1971, it is still one of the most used because it has evolved over time and is considered fast, reliable and safe.

FTP Servers are mainly used for data and file backup, that is, as a backup server, however it has other uses.

Mail Servers:

Mail servers are computer applications that allow the exchange of messages through electronic communication systems, which began to be developed since 1971.

These work as the postal service, the big difference is that instead of taking days or weeks to send large packages and paper documents, they send digital data and electronic information in a matter of seconds, allowing almost immediate communication.

In order for the proper functioning of these services to be carried out, it is necessary to make use of different types of network protocols, which are basically the regulations or rules that allow information to circulate in a computer network. The most common are the HTTP, SMTP, POP, POP3, and IMAP protocols.


types of servers

IRC servers:

It had its beginnings in 1988 and was a great success because it managed to generate immediate and real-time written communication between two or more people through the internet.

Internet Relay Chat by its acronym in English, is currently one of the most used chat services, which basically consists of several servers being connected to a network, so that anyone around the world can join one of these and Chat with any other user connected to the Internet. Like an FTP server, it is also based on a client-server architecture.

The IRC allows you to participate in public chat rooms and at the same time hold private conversations; limit the maximum number of participants and even expel those unwanted members. In addition, it allows the exchange of other types of files, such as images or sound, so that it generates greater interaction in chat rooms.

Game Servers:

The well-known Game Servers, as the name says, specialize in hosting video games, that is, providing the space for their creators or developers to offer their games on the internet. In addition, this server has the function of collecting the information of each connected player and sending it to the rest of the participants immediately so that games can be generated in real time.

There are two types of video game servers, listening and dedicated. Listening servers are mostly used by small groups of players who wish to have videogame sessions sharing a local network. They work since the processing and bandwidth requirements are executed from the same machine.

Dedicated servers work independently, operated by the video game developer client. These allow you to control and update the content constantly, and its biggest advantage is that, being located in data centers, the power and bandwidth they offer allow a large number of simultaneous players to exist.

Proxy servers:

A proxy server functions as an intermediary between two other computer systems, contributing to network security. By not requiring direct communication between the sender and the recipient, it makes possible the exchange of data and information between systems that have incompatible IP addresses.
In addition, it is a fundamental part of the Firewall, which is the software that protects systems from attacks by public networks such as the theft of confidential data, the loss of valuable information, and even the denial of services from our network.

Among other functions of the proxy is the generation of what is known as Cache, which serves to quickly respond to requests from a local network, and this is achieved by a temporary copy of the data obtained from the Internet. It helps save time and bandwidth.


A Virtual Private Network is a technology used to make secure connections to a private network of one or more computers without being physically in the same place. This helps to protect our information, since connecting to a VPN generates a type of “virtual tunnel” through which all our information passes, and the data sent or requested is encrypted until they leave the VPN.

Making use of this technology has certain advantages. The first and most important of all is, as already mentioned above, the protection of your data. However, another of the great benefits is the access to any place of the network without geographical restrictions.

Database server:

provides database services to other programs or other types of computers, as defined by the client-server model. You can also refer to those computers (servers) dedicated to running those programs, providing the service.

Security Server:

It has specialized software to stop malicious intrusions, normally they have antivirus, antispyware, antiadware, in addition to having redundant firewalls of various levels and / or layers to prevent attacks, the security servers vary depending on their use and importance.
