A server is a computer and its software that provides services to other computers. The server listens and responds to requests from other computers. Other computers that request this are the server's "clients". They are called servers because they serve things and provide services to other computers.

The server must always be on because turning it off will stop service to other servers. When a server fails (it crashes or has an error), the services it provides are unavailable, causing problems for other network users.

Different Types Of Servers

Let's look at the main types of servers and explain the purpose of each one.

1. E-mail server or mail server:A computer in a network that acts as a virtual post office. Transmission and storage of e-mail messages across networks. These servers include software that can store mail for local users and user-defined rules that determine how the mail server interacts with specific message destinations. These servers are usually divided into two servers, one for incoming mail (called POP3) and one for outgoing mail (called SMTP).

2. POP3: The server keeps incoming e-mail messages until it checks your e-mail and forwards it to your computer at your request. Manage to send emails to the Internet. An SMTP server handles outgoing emails and uses a POP3 or IMAP server for incoming emails. When the user issues a send Prime Hosting, the server sends it. Another type of mail server is IMAP.

This allows you to work with your emails without first downloading them to your computer. Preview, delete and organize messages directly on your mail server without downloading them to your computer. Examples include emails from Yahoo, Hotmail and so on. Many fax servers do the same as mail servers but send and receive faxes.

3. FTP server:"File Transfer Protocol", one of the oldest file transfer protocols on the Internet. They are used to transfer files between computers securely (send files from one place to another). FTP ensures file security and transfer control. These servers are used to upload web page files to web servers, image files, videos, to make backups, etc.

4. Web Server or Web Server: All web pages you can see on the internet are stored on web servers.

A web server stores the web files and provides them to clients who request them by transferring them over the network using browsers. The client requests it through his browser, and the web server sends it to Different Types of Browsers to view it. Web files include text, images, videos, etc., only browsers can view.

What Is Network Application

Network application allows an application to connect to network resources that require domain credentials. For example, an application that retrieves data from SharePoint servers on a private intranet. With this functionality, you can use your credentials to access network resources on a network that requires credentials. An application with this functionality can impersonate you on the network. You don't need this functionality for your app to access the Internet through an authenticating proxy.
