In this blog, we will explore what a server is and how it works.
The term server was introduced in computing many years ago. What the role of the server is on the internet and why you should know it is a basic question. You must have experienced many times that when we want to do something in the bank, we are told that the server is down or that there is a server error.
So it simply means that this is an issue that can be important. Especially if you are dealing with areas like computer science or technology. Secondly, if you want to host your own website, you should also find out about the server. Although this name sounds like a very technical word, it is actually very simple to understand.
In this blog post, you will get comprehensive information about the server so that after reading it, you will know exactly what a server is. So, what is a server and what types of servers are there?
What is a server?
What is a server? A server is a computer programme or device. It makes data available to other computers. It can deliver data to the system via a local area network (LAN) or a wide area network (WAN) via the Internet. We can also think of the server as a part of the computer on the network that manages the network resources. A physical computer running a server programme in a data server is also called a server.
Since there are many different types of servers, their functions are also different. For example, a file server, which you can also call a storage device, is designed to shop files. Whatever data is available across the internet, whether it is website data, YouTube videos, photos or PDF files, they all reside on the file server. If you read how the server works, you will understand it.
Some other important servers are web server, mail server, app server and database server.
There are many other types of servers which we will talk about below. Servers are completely dedicated. This means that they do not perform any task other than that of server. However, on multiple operating systems, a computer can run multiple programmes at the same time.
This means that some computers can also be a dedicated server and be used for other tasks.
Why are servers used?
Server is a word you hear over and over again in the computer field. The name “server” is derived from the word serve, which means to serve. In effect, it serves the website for the user on demand. Asking why a server is needed will help you a lot in understanding the server.
Suppose you want to create an online website, then to shop it you need a place which is connected to the internet network. This place is called a server and all websites use some kind of server.
So let us take a look at some points that indicate the need for a server.
1) A server provides us with network security. When you create an individual or group account on a website, your data is stored on that website’s file server. These servers have the right to protect this data from being accessed by other users.
2) The server always runs 24 × 7. Even if the hardware fails, it provides server services even in this case. If it is a PC, the server automatically shuts down when the power goes out. This can cause your data to be lost, but the servers are equipped with many power supplies. For this reason, the failure of a power supply does not affect normal system operation.
3) The server uses many hard drives working in the RAID configuration instead of the single hard drive used in PC to avoid data loss or interruption, therefore the server has a higher storage capacity.
4) The server allows us to access the file storage and many computers on the network. The server is also called the computer used in the network. A server usually has more memory, storage space and processing power than a client computer.
Types of servers
There are many types or kinds of servers. Different servers function differently. From website hosting to internet network security to email and video services, all tasks are done by a server. So let us find out about the many types of servers in use today.
- Web server: A web server is server software or hardware that runs websites. It is also referred to as a computer programme. Its main function is to shop, process and deliver the web page to the user. It uses the Hypertext Transfer Protocol (HTTP) for internal communication. We have already given information about what the protocol is.
- Application server: An application server is a programme that manages all application operations of the user’s and company’s back-end business application or database. It is a framework where an application server is used to develop and run all applications. There are different types, such as PHP, Java and . NET.
- Proxy server: Also commonly known as a “proxy”. It acts as a gateway between the user and the Internet. When a client connects to a proxy server and requests a service. For example, for a website, it checks how it can simplify and control the complexity of this request. It acts as an intermediary between the client programme and the external server for sharing network connections, filtering network data and caching data.
- File Server: Primarily provides space for storing files within a network. These files can be anything. In the server model, from text documents to multimedia to photos, file servers are called computers. Because it is responsible for storing and managing data files. Files can be accessed from other computers on the same network.
- Database server: A computer system capable of providing services related to accessing and retrieving data from databases. It is like a warehouse where website data and information is stored and maintained.
- Mail Server: As the name suggests, it is a server that processes and delivers mail over a network on the Internet. A mail server is also known as a mail server transfer agent (MTA) or Internet mailer. All emails we send go through a series of mail servers. When I send an email, it immediately arrives in another email. But in reality, it’s a complicated process of sending emails.
- FTP Server: Its full name is a file transfer protocol whose mission is online file transfer. When you request a web page in your web browser, the browser uses the same protocol to display that file. FTP is a method of transferring files to any computer in the world that is connected to the Internet. how does the server work
