2. Rack server
A rack server, is a rack-mounted server and a computer dedicated server to use as a server and designed to be installed in a framework called a rack. The rack contains multiple mounting slots, each designed to hold a hardware unit secured in place with screws.
3. Blade server
Blade server is a server architecture that houses multiple server modules in a single chassis. It is widely used to improve system management and either self-standing or rack mounted, the chassis provides the power supply, and each blade has its own CPU, RAM and storage.
There are some common servers used by organisations are mention below.
1. Proxy server
It is a server that is called a computer, acts as an intermediary between the user's computer and the Internet and allows client computers to make indirect network connections to other network services.
2. Mail server

3. DNS name
It is a program that uses HTTP to serve the files that form Web pages to users, in response to their requests. Dedicated computers and appliances are may be called as Web servers.
4. Application server
This type of server is acts as a set of components accessible to the software developer through a standard API defined for the platform itself. These are usually performed in the same running environment as their web server(s), and their main work is to support the construction of dynamic pages.
5. Active Directory Server
Active Directory (AD) is consists of several services that run on Windows Server to manage permissions and access to networked resources. AD stores data as objects and it is a single element, such as a user, group, application or device, such as a printer. These objects are normally defined as either resources like printers or computers or security principals such as users or groups.
6. DHCP SERVER
Here DHCP stands for a dynamic host configuration protocol. Which is a network protocol used on IP networks where it is automatically assigns an IP address and other information to each host on the network hence it can communicate efficiently with other endpoints.

8. Terminal Server
A terminal server is a network device that enables connections to multiple client server network systems and connect to a LAN network. Microsoft introduced this concept by releasing terminal services as a part of the Windows Server OS.
9. Print Server
It is also called as printer server, which is a device that connects printers to client computers over a network. Print server accepts print jobs from the computers and sends the jobs to the appropriate printers.
10. Real-time communication server
It is a term used for any live telecommunications that occur without transmission delays and it is nearly instant with minimal latency. RTC (Real-time communication server) data and messages are not stored between transmission and reception.
11. FTP server
It is a network protocol used to move computer files between a client and server. FTP (File Transfer Protocol) is built on a client-server model architecture using separate control and data connections between the client and the server.

14. Open Source Server
It is a program whose source code is made available to use or modification as users where open source software is always developed as a public collaboration and made freely available.
How Does Server Works?
Operating System
Client Computer:
Server Computer:
A client computer generate a connection to a Server computer and accesses the services installed on the Server Computer. It is not meant for a network user to browse in internet or do spreadsheet work. A Server computer is installed with appropriate OS and related Software to serve the network clients with one or more services.
An operating system is the most important set of software programs which are loaded initially into any computer-like device by a bootstrap program. OS controls all the resources in a computer, including networks, data storage, user etc.Network Operating (Systems Server Operating Systems)
A Network Server computer provides its services to a group of Network Client devices which has more computing resources like Processors & Processing Power, more Physical Memory (RAM), and more Storage Space etc. The Server computer machine runs on Server Operating System, which is called as Network Operating System (NOS), and that normally has more features and processing capabilities compared with the client computer's Operating System. The server may be installed with special software to perform a function like a Server.
