Server

What is Server?

A server is a computer program or equipment that offers a service to another computer program and its users, referred to collectively as the clients. The physical system that a server program runs on is sometimes referred to as a server in a data center. That machine may be a dedicated server, or it could be utilized for anything else.

1. Web Server​

The server that is in charge of publishing a website on the internet is known as a web server. A server that provides hosting, also called "hosting", over the internet protocol is called a web server. The renting of space required to publish Web pages on the Internet is referred to as "hosting". Hosting means putting pages, images, or documents meant for a website on a computer that internet users use to access them. Apache, Microsoft's Internet Information Server (IIS), and Nginx are the most popular web servers on the Internet.

The most common web servers are as follows:

• Apache HTTP Server: The Apache Software Foundation created the world's most popular web server. Apache is an open-source web server that can be installed on Linux, Unix, Windows, FreeBSD, Mac OS X, and many other operating systems. The Apache Web Server is used by over 60% of web server computers.

• Internet Information Services: Microsoft's Internet Information Server (IIS) is a high-performance Web server.

• Lighttpd: Lighttpd, pronounced lighty, is a free web server that comes with the FreeBSD operating system. This open-source web server is quick, safe, and uses far less CPU power. Lighttpd may also be run on Windows, Mac OS X, Linux, and Solaris.

• Nginx: Nginx Web Server is a critical component in the client-server computing environment, providing business-critical information to client systems. Like Lighttpd, it is an open-source web server that is known for being fast and needing few resources and time to set up. It is mostly used for caching, streaming media, load balancing, managing static files, auto-indexing, and other similar tasks. Nginx handles requests on a single thread, employing an asynchronous technique rather than generating new processes for each request made by the user.

  2. Database Server​

  A database server manages a database and provides database services to clients. The server manages data access and retrieval as well as the completion of client requests. A database server is a computer that runs database software and is dedicated to providing database services. A database server is made up of hardware and software that is used to run a database.

• Here are a few well-known examples of database servers.

  • Oracle: Oracle is the most commonly used database for object-relational database administration, and the most recent version is 12c (12 Cloud Computing). It supports various Linux, Windows, and UNIX versions.

  • IBM DB2: IBM DB2 was designed in C, C++, and Assembly and was initially released in 1983. Its setup and installation procedures are straightforward, as is data access. As a result, it aids in the storing of large volumes of data, up to petabytes.

  • Microsoft SQL Server: This server was first introduced in 1989. It is written in several languages, including Assembly, C, Linux, and C++. It can run Linux and Windows. It enables multiple users to use the same database at the same time.

  • MySQL: MySQL is becoming more popular for many web-based applications. It is available as both a freeware and a premium edition.

  • 3. Email Server​

A mail server, also known as an email server, is a computer system that sends and receives emails. When you send an email, it passes through several servers before arriving at its destination. While this process is quick and efficient, there is a significant amount of complexity involved in sending and receiving emails.

• SMTP: The SMTP protocol handles all incoming mail and sends emails. SMTP stands for Simple Mail Transfer Protocol and refers to the outgoing mail server. Consider SMTP to be the transport of your email across networks. Your emails would be useless without them.

• I**MAP / POP:** There are two types of incoming mail servers-POP3 and IMAP. Post Office Protocol version 3 (POP3) servers are well-known for getting your computer's Inbox contents. IMAP servers, which stand for Internet Message Access Protocol, are used for one-way mailbox synchronization. IMAP is used as an additional protocol retrieval application on a mail server.

4. Web Proxy Server​

People rarely consider how complicated the internet is. The threat of crimes such as identity theft and data security breaches is growing. To protect themselves, many people employ proxy servers or Virtual Private Networks (VPN). A proxy server is a web server that serves as a conduit between a client program, such as a browser, and the actual server. It sends queries to the accurate server on the client's behalf and sometimes fulfills the claim itself. Web proxy servers offer two key functions: they filter requests and increase performance. In addition, there are reverse proxy servers that reside between web servers and web clients. Requests from web clients are routed through reverse proxy servers to web servers. They are used to cache pictures and pages to drastically minimize the strain on web servers.

5. DNS Server​

The Domain Name System (DNS) is the Internet's telephone directory. DNS is responsible for finding the correct IP address for websites when users enter their domain names, such as 'google.com' or 'facebook.com,' into web browsers.

6. FTP Server​

FTP is a network protocol that is used to transfer files between a client and a server on a computer network. FTP is a well-known protocol that was developed in the 1970s to allow two computers to transfer data over the internet. One computer serves as the server, storing information, while the other serves as the client, sending or requesting files from the server. The FTP protocol's primary mode of communication is normally port 21. On port 21, an FTP server will accept client connections. FTP servers, as well as the more secure SFTP Server software, carry out two basic functions: "Put" and "Get."

7. Cloud Server​

A cloud server is a pooled, centralized server resource that is hosted and distributed across a network -typically the Internet- and may be accessed by multiple users on demand. Cloud servers provide all of the same services as traditional physical servers, including processing power, storage, and applications. Cloud servers can be situated anywhere in the world and provide remote services via a cloud computing environment.

8.Application Server​

An application server is software that runs on the server and is written by a server programmer to provide business logic for any application. This server might be part of a network or a dispersed network. Server programs are typically used to give services to client programs that are either on the same system or a network. Application servers reduce traffic while increasing security. It is not possible to achieve ideal web server agility by handling both HTTP requests from web clients and passing or storing resources from numerous websites.
