* A server is not necessarily a machine of the latest generation large and monstrous, is not necessarily a supercomputer, a server can be anything from an old computer, even a very powerful machine (eg web servers, large databases, and so on. Processors Special and up to several gigabytes of memory). All this depends on the use given to the server.
