What is Data center?
[[Image:Datacenter-telecom_edit2.jpg|thumb|right|upright|A view inside data center.]] '''Data center''' is a special [[building]] or [[room]] built to house a lot of running [[computer]] [[Server|servers]]. It provides fast [[Computer_network|network connections]] between servers to communicate and process a lot of [[data]], and some for talking to the outside world. There are [[Air conditioner|cooling machines]] to deal with heat from each server and control [[moisture]] to stop computers from breaking too fast. There is often an emergency [[electricity]] supply from an [[Uninterruptible power supply|UPS]] (or [[diesel generator]]) to make sure that computers still work even when mains power goes out. And there are usually some kind of [[Fire extinguisher|fire extinguishers]] there to keep fire from computers if there happen to be any. Data centers are normally built and used by [[company|companies]] that need a lot of always-on computer, companies that are hired to do [[computing]] for someone else (for example, ones that do [[Web hosting service|web hosting]]), and most modern [[telecommunication]] companies. ==Related pages== * [[Cloud computing]] * [[Supercomputer]] * [[Internet]] [[Category:Computer networking]] {{Tech-stub}}
