Finding Out What A Rack Server Is

We're going to be talking about what a server is

, as it relates to the world of computers and computing. In this regard a server is a computer program that works to attend to the needs and demands of other applications (these are called clients). Those programs could be running on a different computer system or on the same one as the server program. A server can be an actual computer, or a number of computer systems, whose purpose is to operate one or more computer programs functioning together on the same network.

A computer server is usually a combination of both software and hardware, such as a file server, mail server, print server or a database server. Every one of these serve different and unique purposes. A good example of this would be when you enter a request into a search engine, that request is sent from your personal computer over the net to one or more servers that have the applicable pages saved on them. The answer or results are then sent back, by the server program, right to your computer.

You're probably asking yourself why servers are needed. They're needed so that the Internet will work effectively. If there were no servers saving web pages on them, you could not send out a search, because there would be nothing available for you to look for. This is merely the substantial public need for servers to be available. Servers also store applications that tell search engines how to function, as well as how web pages are rated so that the system knows what order to transmit the results of a search.

Servers are also needed in the private use of firms. They hold significant databases of the various types of information that these businesses need to retain and have immediate access to. There might be individual servers for each type of information databases and a server that controls how they are used.

It's also the server which allows a business to have a network of computers linked together to be able to access the information. The networking program is a server program and enables or restricts the flow of internal information to only the computers with stored access clearance.

If servers are so important, what occurs when a server breaks down? If a server breaks down, somebody must find out why and make repairs so it can be brought back online. Out on the world wide web there are backup servers. When one goes down and its information or directions aren't accessible but the Internet system will redirect their request and seek the data it needs by using a different server on the system that can do almost exactly the same thing that the server that went down does. It's this back-up system (called a redundancy) that keeps the Internet working 24/7/365.

When we are talking about a server in a company breaking down, it could cause a lot of the work being done to come to a critical stop. Just as the servers online, the server must be fixed and taken back online so the company network system can get back to work. It's for this very reason that corporations have taken a lesson from the internet and have redundant backup rack server solutions in place and a system that will automatically switch to the back if the main server fails.
