Data Center
Data centres are a series of modules rather than a centralised body. Servers, computing subsystems, networking switches, routers, and firewalls, as well as the cabling and physical racks used to arrange and interconnect the IT devices, are all located in data centres.
Power management and supplemental power subsystems, such as electrical switching; uninterruptible power supplies; backup generators, and so on; ventilation and data centre cooling systems, such as computer room air conditioners, are all needed in a data centre.
