A server is a computer or device that offers resources, data, services, or programs to other computers in a network.

A client is also one  computer or device that primarily depends on that parent device named Server. It send request to the server over a network and gets response from it in form of data and information. 

There are various types of server available based on its operation requirement. Those are as mentioned below;

  • File Servers
  • Print Servers
  • Application Servers
  • Database servers
  • Web Servers
  • DNS Servers
  • Mail Servers
  • Virtual Servers
  • Proxy Servers
  • Management Server

Server hardware were changed since the use of it. Several types of server hardware are available as; 

  • Mainframe Server
  • Blade Server
  • Rack Server
  • Standing Server
  • Hypervisor or virtual server


A server have the same components as a computer system i.e. Operating System, RAM, HDD, CPU, Motherboard, Graphics Card, Network Card, etc. 

Name of some Operating Systems: Unix, Ubuntu, RHEL, CentOS, Solaris, Windows Server 2012, Windows server 2019 etc. 

The important one which are being used on frequent, as below;

Application Server: 

An application server is a server designed to run IT, business applications. Application servers often run resource-intensive applications that are shared by a large number of users.

Web Server:

A web server is a server that processes program and data to respond the requests to a client system or users over internet. It uses HTTPS and The primary function of  is to store, process and deliver web pages to users. 

Database Server:

A Database server runs with applications of ORACLE, SQL in the backend and within a restricted zone are high powered, store all the structured data and manage them including managing the backups of those data. All the data from the application server is stored in the DB server. It works in a client-server model.

Email Server:

An email server, or simply a mail server, is an application or computer in a network whose main purpose is to act as a virtual post office. The server stores incoming email for distribution to local users and sends out outgoing messages. This uses a client-server application model to send and receive messages using Simple Mail Transfer Protocol (SMTP).

DHCP Server:

A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices.

DNS Server:

When users type domain names into the URL bar in their browser, DNS servers are responsible for translating those domain names to numeric IP addresses, leading them to the correct website.

NTP Server:

Ideally a protocol used in systems and can be used dedicatedly in servers for Network Time Protocol (NTP) is an internet protocol used to synchronize with computer clock time sources in a network.

Proxy Server:

The proxy server is a computer on the internet that accepts the incoming requests from the client and forwards those requests to the destination server.

This was all basics about servers. You can refer further to read more. Thanks!
