Whats the diff

A server is as the name implies a computer that is serving something. It could be as simple as a printer or a few files. The server does not have to have a "server" OS. I can designate an XP or Win98 computer to be a file server.

Understanding that any computer that is networked can be a server, many servers are not just a workstation with some files on it. Why? Generally the shared files are valuable and often need to be used by many people. Because of the higher workload and importance attached to the servers data, they need to built differently than workstations.

The details can't be answered in 2000 characters or less but you can find them if you are interested.

The best analogy I can make is to say that I typical desktop computer is like a car. A server is like a truck. You have different criteria to evaluate each, but they each are 4 wheeled vehicles. If you evaluate a truck that needs to haul heavy loads, for many years- you don't compare the same specs as if buying a sportscar.

With computers it is the same a server may have multi disc systems to provide redundancy in the event of a drive failure. Special memory is used to correct data errors. Processors are built to handle the multiple requests that may be coming constantly.

If you buy entry level servers, there may be few differnces between them and a desktop. As you go up the ladder a properly built server should be built much differently than a desktop.

Keep in mind a small office may only need a desktop to perform certain basic services. A desktop can be a fine server, just like a sportscar can be fine for hauling your tail around town. If the load gets big enough you might need a truck.
