Server is type of computer program or device that is mainly used to store, receive and send data to another computer program or client, In simple terms server is a device that provides services to another computer.
By the way in case of providing services to other computers it may includes many services such as Web services, Application services and Database services so that there are many kinds of servers. Some of them are following which are mainly used.
- Web server
- Database server
- Email server
- DNS server
- File server
- Application server
- Cloud server
Web Server
It's a computer that runs websites, computer program that distributes web pages as they are requested by the clients. Mainly webservers store data, collect, process and deliver web pages to the users. It handles incoming requests from the web browsers or other client applications and deliver the requested web pages, files or other resource to the clients over the internet. Apache HTTP Server, Nginx, Microsoft IIS (Internet Information Services), and lighttpd, among others are the examples of the popular web servers. Each web server software may have its own configuration options, performance characteristics, and supported features. Web servers always play a crucial role in the delivery of web content and applications, Web servers allow users to access websites, interact with web services, and retrieve information from the internet.Database server
Database basically stores data that can be any kind of information ie_ information about people, their ages, sometimes we manage their salaries, and other many kinds of data there can be whether it's information about people, products, orders or any particular thing to be saved on databases. in layman terms It literally manages data and provides data based services to clients such as saving data, providing personal cloud storage. Information is always written in table form on databases as usual it is written in our daily life, database can contain more than one table in case storing the information because there can be different kinds of information.Email Server
A mail server is also known as an email Server. It's computer system that sends and receives emails. When one email is being sent, it passes through many servers and before arriving at its actual destination while it is quick and efficient. Apache HTTP Server, Nginx, Microsoft IIS (Internet Information Services), and lighttpd, among others are the examples of the popular web servers. Each web server software may have its own configuration options, performance characteristics, and supported features. Web servers always play a crucial role in the delivery of web content and applications, Web servers allow users to access websites, interact with web services, and retrieve information from the internet.
DNS Server
DNS literally stands for "Domain Name System" is the phonebook of the Internet. Just like when users type domain names out there in any browser such as ‘google.com’ or ‘microsoft.com’, DNS is responsible in case of finding out correct IP Address for those sites. Browsers use those addresses to communicate with Origin servers 'the servers where any site is hosted' to access the information that is on any website. It is all because of DNS servers.
File Server
Server Which is responsible for the storage and management of data files so that other computers on the same network can access the files. It enables users to share information over a network without having to physically transfer files.Application Server
It's network computer that stores and runs an application for clients' computers and provides a frameworks to build and deploy web applications and offer services in case of running applications. . These servers are used by software developers who has to build quick applications and have them supported by the server environment in which they are deployed. Application servers can run in conjunction with relational databases.Cloud Server
Cloud servers are virtual servers running in a cloud computing environment that can be accessed by unlimited users. Cloud servers store data and run applications.
Cloud computing is on demand service used to avail and compute the system resources kind of storing data, applications, servers, development tools, networking efficiencies etcetera over the data centers kept some where else managed by cloud services providers. Cloud services providers literally charge all the resources are availed to, as a monthly fee structure for subscription or there might be different plans to follow them because there exist many companies that provide cloud computing services.
Infrastructure of cloud computing involves the hardware and software components required for proper implementation of a cloud computing model.
