The purpose of a Server is to bring additional functionality, or \"services\" to its clients.

While the servers in a company\u2019s data center may appear significantly different from regular desktop computers, this is because they might serve hundreds, if not even thousands, of users daily. Consequently, these servers are built with reliability as a top priority, as they may be mission-critical to the client\u2019s daily operations.\n\nThat said, any computer can be transformed into a functional server. From an old desktop PC to a laptop, even a $35 Raspberry Pi can serve as a server. While these devices may not offer the same performance or reliability as dedicated hardware designed to serve thousands of clients, they can be suitable for personal use as an inexpensive server for your home network.\n\n=== What's the difference between a desktop PC and a server? ===\n\nWhile a standard desktop PC can act as a server, there are a few key differences in the hardware that make dedicated servers different from a standard desktop computer.

The key reason that ECC memory is used over DDR memory is that ECC features single-bit error detection and correction. While an error in a single bit might not seem like that big of an issue for normal computers, bit errors can result in file corruption, and system crashes, which can result in lost important data. ECC memory makes these machines significantly more reliable in storing data and preventing service interruptions by detecting and correcting any bit errors.\n\nA final key difference is the CPUs that are used in servers. ***High-end servers will often take advantage of CPUs that can have anywhere between 8 and 48 cores but with slower clock speeds with single-thread performance***.

One thing that an organization needs to consider when running a server is the cost of electricity over a long period. The typical increase in power consumption can increase by 75% when switching from a 3 GHz CPU to a 4 GHz CPU. An argument can also be made that a faster CPU isn't necessary when you have a server with dozens of cores and threads, then any task that is thrown at the server is extremely parallel. This would mean that single thread performance, while a nice feature to have, is not the limiting concern. If losing 20% of performance per core means that 50% of the cores are seen by the system then it can be considered an overall net win.\n\n== Additional Information ==\n\n* [link|https:\/\/en.wikipedia.org\/wiki\/Server_(computing)|Server Wiki Article]\n* [link|https:\/\/www.servethehome.com\/|ServeTheHome Website]","contents_json":{"type":"doc","content":[{"type":"heading","attrs":{"level":2},"content":[{"type":"text","text":"Background Information"}]},{"type":"paragraph","content":[{"type":"text","text":"In computing, a Server is the designation of a piece of hardware on a network.

What's the difference between a desktop PC and a server?<\/h3><\/div>\n\n

While a standard desktop PC can act as a server, there are a few key differences in the hardware that make dedicated servers different from a standard desktop computer. As stated above, the servers that are in big data centers are built for reliability<\/strong>. As such most data center servers, feature hardware with more than one power supply<\/strong>. Now while these machines can most definitely run on just one of those power supplies, the purpose is to have reliability through redundancy<\/strong>.<\/p>\n\n
