If you have no idea what a server is, have heard about it, and still have doubts about what they are, this article is for you. A server is a powerful computing device used to store, distribute, and supply information through what is known as the “CLIENT-SERVER” model. In such a model, the client could be a computer or an application that, in order to work, needs the information that the server. However, authorization had to be pre-set for the server to distribute and process the client’s request.
Servers can be physical or virtual. Physical servers, which are part of what we know as hardware, will also be identified as “hosts” and these are installed in a rack type of rack metallic shelf (also called tower) which is integrated into a network of software-based nodes.
On the other hand, virtual servers (VPS, Virtual Private Server) are software that provides services to other programs (clients).
Servers are continuously taking requests, as they are part of a network that needs to be supplied with updated information, therefore, most servers are always ON. If a server were to go down, none of the clients would be able to obtain any information they may need. Therefore, servers are often programmed to be fault-tolerant.
For Example, If we go to the Bank to make a deposit and the server is down, the representative will be unable to process our request until the server or backup server is running again. If we were to give our deposit and neither the server nor the backup server were up and running, they would not be able to hand you a genuine receipt of the transaction with the date, time, order number, and any other that goes printed at the exact time our request was processed.
