What is a server and how does it work
a server can be called a powerful computer, which is designed to store information and provide access to it from remote client devices. The type of data stored on the server may depend on its type and purpose.Now there’s even a choice buy servers used is huge, and the more developed the country, the larger it is.
What is a server in simple words
To answer this question, you need to understand where the word “server” comes from. It is based on the English verb to serve, which translates as “to serve.” So, a server, in simple words, is a special computer that serves to ensure that this or that information network (for example, a local one) can fully function.
The term “server” is inextricably linked with another – “client”. A personal computer, mobile or other device that is located on the same network with the server, sends some requests to it and receives the required information from it is called similarly. There is no point in the existence of a server without client devices associated with it.
What is the server for?
Depending on its type and purpose, this machine can perform various useful functions:
- store information from one or more sites. This is how the servers of Internet providers providing hosting services work;
- coordinate the interaction of many computers located on the same network. A classic example is game servers;
- used to store corporate data and make it accessible to employees. One likely example is a server at a company’s central office where an accounting database is stored and regularly updated.
These are just some of the common ways to use servers. Below we will consider in detail the existing types of these machines and discuss their application in more detail.
It is important to protect servers from large changes in temperature and humidity, flooding, fire and other force majeure situations. For this purpose, data centers and large companies equip special server rooms, which deserve a separate review.
Increased attention should be paid to the server software that runs the required hardware. Conventional operating systems – perhaps known to everyone, the same Windows – in this case are poorly suited or not suitable at all. Server versions of the OS are used – both those created by Microsoft and those included in the Linux brand. The latter, by the way, are widely used as they ensure server stability, data security and operational flexibility. Working with a server OS of the Linux family (for example, Ubuntu Server) requires separate knowledge, so data centers and companies hire competent IT specialists.
If we are talking about a small server that does not require special functionality and computing power, a regular operating system may be suitable. Thus, Windows capabilities are more than enough to set up FTP and organize the work of a file server accessible to a limited number of people.

If we are talking about a small server that does not require special functionality and computing power, an ordinary operating system may be suitable. In this case, Windows capabilities will be sufficient to make FTP settings and set up a file server accessible to a certain circle of people.
