What is a Server?
A computer or a system which provides functionality, services, resources, programs, or data to other programs or networks (known as clients), is called a server.
The computer that shares programs with client machines is considered a server. It shares information or data with multiple clients (other systems). A server is any device through which information or data can be transferred to other systems.
Servers are data storage and processor device that can be hardware or virtual storehouse, located on the internet. The computers and software systems work as servers that attach to a network.
Types of Servers
The major types of a server are discussed below.
- Web Server
This type of server focuses on serving web content to clients. It is an open-source server, which connects stored information, uploaded on an internet website, to your computer. It gives access worldwide through public or private software.
- DHCP Server
DHCP (Dynamic Host Communication Protocol) is used to customize the network setting of client computers. This server helps to configure the static IP address and other network settings dynamically to LAN computers.
- Proxy Server
A proxy server works as an intermediary between a client and a server. It accepts the traffic that comes from the client and sent it to the server. It filters out various harmful internet entities.
- FTP Server
File Transfer Protocol is used to transfer files from one system to another. With this type of server, you can move your uploaded file from the computer to the server and extract the downloaded file from the server to your computer. FTP is used to connect two computers with each other to transfer data safely.
- Application Server
The application server is used to connect clients to application software through a virtual server connection. It allows users to use web applications without direct installing any copy of them into your system.
- File Server
File servers share files or folders over a network. It allows faster data retrieval and writing or saving files on a computer. Through this server, users can download and upload shared files, and the permissions to access files are controlled by the organization or administrator.
- Database Server
A database server is a high-powered computer that runs database software that helps companies and users store retrieve, manage or change files, etc. It offers a company to update, retrieve or save data in a simple way.
- Mail Server
This type of server powers mail services. It simply stores and delivers emails to clients through an email service platform.
- Print Server
It is a type of server which connects the printers to the client`s computer over a network. It helps the organizations to manage files in a printer queue and facilitate the user`s printer workflow.
- DNS Server
The server contains a naming database in which the internet domain name is located and translated into IP addresses, which is the Domain Name System Server. It is the phonebook of the internet that connects web browsers with websites. It converts the web addresses into IP addresses.
- Gaming Server
This type of server hosts multi-player online games and connects users from all over the world. It enables several computers and gaming devices to play multiplayer video games like Pubg.
- Collaboration Server
A collaboration server is used to share work with multiple users in an easy way. It allows to share and save files, applications and other large amounts of data.
- Monitoring and Management Server
A server`s availability, performance, security and other operation-related processes are review and analyzed in monitoring server. It manages the server`s performances and resources like CPU usage, I/O, data and process.
Server basically plays a role of sharing data and resources and distributed work among several system (client computers). It receives, store and share data with other networks. It stores data and make it accessible for organizations and users through internet or internal networks.
Server works in tandem with an operating system in order to listen and respond to user request. It also act as a safeguard and verify the identity of the user before giving access to the network.
Components of a Server
The major components of a server are:
Central Processing Unit (CPU) is the main equipment of electronic server and the centre of all processing within a server drive. It controls the all functions of a server.
- Hard Disk
A hard disk saves all data of the user and the software for a computer. It provides fast speed, high reliability, hot swap and more use of SAS interface as compare to computer drive.
It connects the server`s all parts. The size of the motherboard dictates the amount and numbers of storage and hard drive that connects to the server.
Memory is an important part of server; it works like bridge to interconnect the CPU. It dictates the available storage amount.
- Network Connection
In order to function properly, server needs a connection with a network. Server need a good network connection to receive and respond to your requests.
