What is a server?
A server is a computer which serves data to other computers or users. A server can be any type of computer or hardware device. It can also include a computer program that can send data to other computers. Clients are the devices that receive requests and respond to them.
The Internet uses the term “server” to refer to a computer system that responds to requests for web documents and then sends them to the client. The client/server network is the combination of the server and its clients working together on the computer.
Different types of servers have different tasks. They serve users by providing all information they need.
Here’s an example of a server:
If we view any YouTube video or search for information in our web browser, any results that we see on our device are stored in the server.
A server can be described as a computer. There are many types of servers with different capacities. Installing the program on a regular computer or laptop will make it work as a server.
These servers are known as non-dedicated servers, because they aren’t available 24 hours a days. These servers can only be used in a few places, such as at home, schools and colleges, hospitals, or offices. these are also known as local networks.
What are dedicated servers then? Dedicated servers are servers that can run 24×7 to provide data and information to their users. These servers can be very expensive because of the high quality and speed of the RAM and processors.
Searching in Google will give us results only from dedicated servers. Let’s look at the different types of servers.
Server works in simple terms
To view a YouTube video, someone must first search for the name of the video in YouTube’s search field. It generates a request after it searches, and then goes through YouTube’s server to retrieve all of its data.
The server will find the video you requested, and then send it to your device. After that, he can enjoy the video.
Similar to this, different types of servers function in the same way. Accessing various types of servers via the Internet allows us to download files, browse, send email, and use social networking sites.
Types of servers
There are many server types available to meet the digital age’s needs. These are just a few of the many services that require different types servers:
1. Web Server
A web server is a server which runs on websites. It can also be called a computer program. Web servers serve three main functions: store, process and deliver.
When we search the internet using web browsers such as chrome, Mozilla, or internet explorer, we get the URL request and the web server then sends the data to suit the user’s needs. These servers usually display the data in formats like images, text and video.
HTTP (Hypertext Transport Protocol) is the protocol used by web servers. It serves files to users who create web pages. Web servers are also used to refer to dedicated computers and their applications.
2. Email Server
The email server allows you to send emails to your receiver or to receive them from the sender. It also stores all details of users’ accounts on the server. Also known as the mail server transfer agent (MTA), or internet mailer, an email server can be used to send and receive emails.
SMTP is used to transmit mail to people. It first connects to SMTP to identify the address of the person to whom mail should be sent. Then mail goes to the intended recipient. These servers are basically a virtual postal office.
3.Application Server
Application Server is a framework. It is the environment in which applications can run. Application Server is a combination of a server operating system (OS), and hardware that performs computing-intensive operations as well as other services for the application.
These server types can be used for developing and running a web-based app. There are several types of Application Servers, including Java, PHP, and.NET Framework.
An application server has key features such as data redundancy, security, data/application, high availability, user administration, load balancing and a central management interface.
4.Database Server
A database server is a computer that allows users to retrieve and access data from databases. Access to the database server can be made from either the user’s computer’s “front end”, or from the remote server.
It will then give the requested data after accessing the database.
These servers look similar to a warehouse where website data and information is stored and maintained. A database server is used by many companies for data storage. Access to the data is made possible by query labels that are related to the database. SQL is one example of a query language.
5. FTP Server
FTP stands to File Transfer Protocol. FTP is an old Internet service that allows users to securely transfer files via the Internet. The protocol is used by the server to display your file when a client requests it via a web browser.
You must upload a page you created on your computer to the server hosting your site. FTP allows you to secure files, control their transfer, and organize them on the server.
