Server Explanation

Server is a computer system designed to process requests or requests and send data to other computers via the internet or local networks. The basic function of a server is to receive incoming network requests and store various types of data.

Any data stored on the server can be in the form of documents and information. Data storage on the server can indeed be used to run various services, for example to send emails, open websites, stream videos, and play games.

Server History

In 1989, Berners-Lee proposed to his company CERN (European Organization for Nuclear Research) that this project was created to facilitate the exchange of information between researchers using a hypertext system. On the research results of this project he wrote two computer programs including:

A browser called WorldWideWeb

the world’s first web server known as CERN httpd, which runs on the NeXTSTEP operating system.

Then from 1991 to 1994, several operating systems adopted these two applications because of the simplicity and effectiveness of technology to visit and exchange data via the World Wide Web.

Initially these two applications were only used by research organizations but have been developed and used in educational environments to the business sector.

In 1994, Tim Berners-Lee has decided to standardize the World Wide Web Consortium (W3C) organization to regulate the continued development of other related technologies such as HTML, HTTP, and so on through a standardization process.

How Servers Work

The way the server works is that it works according to client requests. For example, the computer that is running will work to find the information we need. Then the server will find what information the client needs. So that we can access the content on the website.

All types of servers work by performing their respective functions. Starting from data storage to serving protection to the client. In some types of servers have several different types of services.

The computer that will be used as a server will be different from other computers. From the device specifications, it is certain that the server will be much higher because it supports large data processing, while the operating system is also server-specific, namely Linux Ubuntu Server or Windows Server.

Server Function

The server functions include:

    1. Storing data and information

Where data storage can be sent by the client, there are several types of documents or information that can be stored on the server. This server has a large capacity so that it can accommodate a lot of data. So between one client to another client can exchange data at the same time.

    2. Manage transfer traffic

Server devices have high RAM and storage capacities, so they can manage communication and transfer of information to clients.

    3. Serving client computer requests

The server can serve all client requests, both for data requests and applications to run. The operating system is fast, safe and easy so that clients can work safely and more effectively.

    4. Provide databases

As for large companies that utilize functions to implement big data, however, all stored data can be processed and can be accessed by users.

Server Benefits

Servers have benefits according to needs, including:

Guaranteed data security

With this server, we can store and maintain all data more securely and can monitor it at any time. In addition to data, there is also some data stored by the client which can also be accessed easily and quickly as needed.

Save cost

Servers can save costs for buying devices needed for data storage. Servers can also store a larger capacity than computers in general. So the client does not need to buy a lot of hard drives because the server’s storage capacity is much larger.

Data management made easy

It will be easier to manage the documents and information needed precisely. In addition, the process is also fast. Does not require a long server time also guarantees the storage of data stored by the client. For now, there are two types of server storage, namely cloud-based or cloud-based where data is stored with a much larger storage allocation.

Maximizing performance between teams

Servers can optimize the cooperation or collaboration of each team or department. Where a technology and information business requires to work together not offline or demanded online. So that the server plays an important role in optimizing and increasing the productivity of every employee in the company or related agency.

Server Application Types

If you want to know what types of servers are, here are some types of server applications that you need to know:

Web Server

When talking about web servers, this can be seen from two perspectives, namely from the software and hardware side.

On the hardware side, a web server is a computer that stores web server software and website component files (for example, HTML documents, images, CSS stylesheets, and JavaScript files).

Meanwhile, from a software perspective, a web server includes several parts that control how web users access the hosted files. At a minimum, this is an HTTP server.

Mail Server

Then there is the mail server. Mail servers are also known as mail server agents, or MTAs. It is an application that receives incoming emails from local users and remote senders and forwards outgoing messages to send. The computer dedicated to running this application is also called a mail server. Microsoft Exchange, Exim and Sendmail are common examples of mail server programs.

Email servers work with other programs to create messaging systems. The messaging system includes all the apps needed to keep email running smoothly.

Application Server

Then there is a type of server called application server. Application servers. An application server is a type of server designed to install, operate, and host applications. In the early days of application servers, there was a huge growth in the number of applications brought to the Internet. The apps are getting bigger and bigger with the demand to add more functionality to the apps and they are becoming more complex to run and maintain.

There is a need for some kind of program on the network while it will share application capabilities in an efficient and organized manner.

Database Server

The type of server that is very often found is a database server, of course you are familiar with this. The database server is used to store and manage the databases stored on the server and to provide data access for authorized users. This type of server stores data in a central location that can be backed up on a regular basis. It also allows users and applications to access data centrally across the network.

A large number of databases used in your organization can be stored on a single server or a group of servers specifically configured to protect client data and service requests.

Database server can be said to mean a network computer on a network dedicated to database storage and retrieval of data from databases. The database server is a key component in a client/server computing environment.

FTP Server

Have you ever heard of FTP servers? FTP or short for File Transfer Protocol server in its simplest definition, is a software application that allows the transfer of files from one computer to another. FTP is a way to transfer files to any computer in the world that is connected to the Internet.

If defined very simply, FTP is the standard network protocol used for file transfer between clients and servers on a computer network.

DHCP Server

What is the meaning of DHCP server? A DHCP server is a network server that automatically assigns and assigns IP addresses, default gateways, and other network parameters to client devices. It relies on a standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast requests by clients.

The DHCP server automatically sends the necessary network parameters for clients to communicate properly on the network. Without it, network administrators would have to manually manage each client that joins the network, which can be tricky, especially in large networks. DHCP servers typically assign each client a unique dynamic IP address, which changes when the client’s lease for that IP address expires.

File Server

The next type of server application is a file server. A file server is an example of a central server in a computer network that allows connected clients to access the server’s storage capacity.

This term includes the hardware and software required to implement such a server. As long as they have received appropriate authorization, accessing users can open, read, modify, and delete files and folders on the file server and even upload their own files to the server.

Proxy Server

Have you ever heard of proxy servers? A proxy server is a system or router that provides a gateway between a user and the internet. Hence, it helps prevent cyber attackers from entering private networks. It is a server, which is referred to as an “intermediary” because it runs between the end user and the web pages they visit online.

When a computer is connected to the internet, it uses an IP address. This is similar to your home street address, telling incoming data where to go and tagging outgoing data with a return address for other devices to authenticate. A proxy server is basically a computer on the internet that has its own IP address.

Game Server

Have you ever played online games? Online games also have their own server right? A game server is a computer that acts as the central authority for determining the current state of a multiplayer game.

Players send server updates about what they are doing in game it could be running, jumping, taking damage, fishing, you name it. The server interprets the input and returns the information to the player.

Streaming Server

In essence, streaming actually refers to the constant state of media transmission that occurs over the internet from the streaming source to your desktop, laptop, smartphone, etc. Thus, the Streaming server is the software foundation that makes transmission possible.


Those are the various understandings about servers, both understanding, history, how the server works, the functions of the server, and also the server applications that turn out to be very many around you in your daily life in using the internet.
