What is a server and what are its types and uses

server, we've all heard this term somewhere or the other, but we probably don't know what it means.

Although it is an essential part of the technological progress in which we live, it is integrated into all the electronic operations that we carry out and it is the basis of the Internet that we cannot do without.

To see in the first what is the server?

To see in the first what is the server

A server is a computer that has high technical specifications and operates non-stop 24 hours a day in order to provide a service.

In general, we can say that these servers connect computers with each other 24 hours a day.

Servers consist of the same components as a regular computer, such as processor, RAM, memory or storage device, motherboard, cooler, and power supply.

  These components are usually much more powerful than standard computers or the computers we use, allowing for greater computing resources and being able to operate 24 hours a day without any problems.

Why did the server appear? What is the significance of its appearance?

In recent years, people have relied on the traditional means of exchanging data by storing it on hard drives.

Of course, these discs were susceptible to damage at any time because they are not resistant to breakage, for example, and therefore loss of the data stored on them is possible although it may have taken you a lot of effort to complete them.

Therefore, it was necessary to find a solution to this problem, and with the beginning of technological development, a solution appeared that would allow the transmission of information in a secure manner. and as quickly as possible between users, even if they are found over long distances.

This solution is what can be called the "peer 2 peer" principle, and it makes it possible to create a direct connection between two devices and thus to exchange information more quickly without the need for external support such as discs. hard, and this connection is made via an Internet cable so that the first device integrates a network connection and the second also.

And here another problem appeared in front of us because one of the two devices could be locked, and therefore they could not be connected at the same time, so it was better to have a third external device on which to store the data.

When the first person calls the second person's device and finds it unavailable, they can retrieve the stored data they need from the external device at any time.

The server must be running 24 hours a day, otherwise, all the applications, websites, and technologies we use will not be able to function.

Server types

The general idea of the server is the same, but the applications are multiple, which brings us to several types of servers, including:

1. Application server: This is the server responsible for running applications and games or storing their data.

2. Virtual Private Server: It is formed when a server is divided into several sub-servers and used separately.

3. Cloud Server: This is a type of modern server similar to cloud storage, fast and secure.

4. Web Server: This is the server on which the worldwide Internet depends and on which websites are hosted.

5. Dedicated server: It is the server dedicated to the service of a specific entity, whether it is a person, a company, or a website, exclusively, so that this entity benefits from all its capacities.

6. Domain name server: It is the server responsible for storing the domain name in the networks and converting it into an IP or IP address.

7. Mail server: whose name is responsible for emails in terms of sending, receiving, and storing, and some companies use it because it secures their emails against hacking.

Servers features and benefits

It is possible to build a serverless network, based on a desktop computer, for example, depending on the purpose of building the network.

For example, a restaurant manager wants to connect surveillance cameras and an employee time monitoring device to a single network and connect it to his cell phone, so there is no need for a server because there is a more alternative simple and cheaper.

Hence the question, why would we build a server-based network then!

This is for several reasons, including:

  1. Centralized network management and control.
  2. Storage of information and data via central hard drives located in the server.
  3. The internet can be connected to all the devices connected to the network hence the usage preview.
  4. Distribution of powers to employees, one employee is authorized to print and another is not, or one employee is authorized to use USB and another is not.
  5. The ability to install any program on the server, and to use this program normally by employees on their devices, thereby reducing the resource consumption of computers connected to the network.
  6. Reduce expenses, for example, one can buy a printer that can be used by all employees.
  7. Provide network protection from viruses.
  8. Backup of information and data.

How to determine the specifications of the server that suits you

While we're talking about servers, we'll also help you determine the capabilities of the right server for you, which depends on many things and factors.

For example, if you are going to build a server for a business, you will definitely consider the nature of the business, the type of services the business provides, the number of current employees in the business, and whether there are company branches in other cities or countries or not.

In addition to many other factors that should always be considered when building any network containing a server, when buying a server you should pay attention to the following specifications:

  1. Specifications of the charger for the server is it suitable for the energy the server consumes or not.
  2. Server cooling units, and it is one of the important parts of keeping the temperature low for the internal components of the server because the servers are running around the clock.
  3. The operating system the server should run on and the most common systems: are Linux and Windows.
  4. The server's CPU processor, where you need to pay attention to its speed and compare it to what the company is doing on the network.
  5. Random access memory (RAM).
  6. Hard disk space.

Server Frequently Asked Questions

1. What is the difference between a server and a data center?

A data center is a group of servers, so a data center can contain hundreds and thousands of servers.

2. Why does the server have to be running all the time?

The server must be running 24/7 because it is the basis of the networks that we use in many aspects of our lives.

3. What are the types of servers?

  • Email Server.
  • Application Server.
  • Database Server.
  • Cloud Server.
  • Domain Server name.
  • Virtual Privet Server.
  • Web Server.
  • Dedicated Server.

Article summary

The server is the basis of the Internet, as it is the basis of most of the technologies that we use on a daily basis in various aspects of our lives.

A server is a computer that has the same components but is generally more sophisticated and capable of running 24 hours a day without interruption.
