Servers basically a dedicated computer that provides services on behalf of clients, such as regular desktops or workstations. It is thus a centralized machine where multiple clients connect via the Internet or in a local area network, and they connect to a server for a specific service. The service could be, for example, searching for a website, accessing data or email, and so on.

Now a server can be dedicated to handle only one of these services, where you will have one server for a website, one server for data storage and one server for email. And this model is what larger organizations use.



Or you can also set up a server to handle each of these services on the same machine, which usually happens in smaller organizations. It therefore depends on the needs of the organization, depending on the setup used.

When people talk about a server in general, they are referring to a powerful, centralized computer that connects customers over a network, and that’s correct. However, a server is not just a physical computer.

How blockchain is different from server?

The Main Role of Servers

A server is actually a role that a computer takes on. Because any ordinary desktop computer can be set up as a server and it does not necessarily have to be a powerful computer. For example, you can set up a network in your home where you can have a regular desktop computer serve as a file server.

The computer has the files in a shared folder and then other computers cannot connect to it to access the files. Or you can also ‘ use a computer to act as a web server, where you would install the website data on the computer, and then connect the other computers to it and retrieve the web page.



However, desktops have their limitations because they are not designed to handle a large workload and they cannot handle many incoming connections from users. And this is not only because of their inferior hardware, but also because of software.

Because desktop operating systems can only handle a limited amount of simultaneous connections. Servers now need to be up and running 24/7 as it is essential for an organization. And if a server goes down, it could endanger a business or organization.

Website Server

So for example a web server. A web server is the host of a website. So, on any website that you visit with your web browser, you connect via the internet with the web server to pull up the desired website.

The web server contains all the data of the website, including the HTML code and graphics, and the web server software is also used.



Email Server

Another type of server is an e-mail server, an e-mail server is the sending and receiving of e-mail, and you will be able to access the e-mail with your web browser, or you can ‘ Use an email client such as Outlook or Thunderbird using email protocols such as IMAP. POP and SMTP.

Computer Server Database

And a database server is a different type of server. This type of server stores data at the back end and is then retrieved from computers up front, for example using queries such as SQL. So these are just a few examples of what servers do, but there are many more.

Desktop Processor vs Servers Processor

Therefore, servers need to be more reliable. They need to be built with robust hardware that can work tirelessly with little or no downtime. For example, a desktop uses a processor that is naturally designed for desktops, such as the Intel Core Series processors.

And a server uses a processor designed for servers like the Intel Xeon processor. A server processor must be fast and have the ability to perform many tasks simultaneously. Now both of these processors are powerful, but there are some differences.



For example, Xeon processors support a multi-processing environment. They are therefore designed to work with other processors. This means you can put two or more Xeon processors on a motherboard designed for servers, which requires many servers to handle a large workload.

Server Virtual Memory (ECC)

But desktop processors do not support this, they are only designed to work alone and not with other processors. And another difference is that Xeon processors support ECC RAM, which corrects the error code memory.

And this type of memory is mainly used in servers. Now Servers must be running at all times and memory errors could bring down a server and what ECC does is that it detects if the data has been processed correctly by the RAM module and it makes a correction if necessary to prevent memory errors.



The use of ECC memory on servers is therefore only an extra precaution to prevent any errors from being served and that Intel Core processors do not support ECC Ram, but AMD processors do. Xeon processors can also support a larger amount of RAM.

servers

Server RAID

They will have a larger memory. And they also have a higher core score than desktop processors. And a server must also have hard-swappable hard drives in a RAID configuration, because if a hard drive failed, there would be no data loss, which happened, and the server would still be running due to RAID.

RAID copies the data to multiple disks and should a hard disk fail, it can be removed and replaced without shutting down the server. And then RAID would automatically rebuild the data on the new hard drive.

And a server must also have redundant power supplies to keep the server running in case of a power outage. And a server must also use a server system, such as Linux, Windows Server, Mac OS server and so on.

Server operating systems are robust and stable and are designed to work continuously and can handle thousands of simultaneous connections. Now there are many different types of servers, and when I mean types, I’m talking about the type of service the server provides.
