A data center could be explained as an advanced warehouse for hosting servers. That's a facility which accommodates a huge number of web servers used by firms for storing data and files or for performing computation services at a big scale. Hosting, search engines and large social networks are only a couple of examples of the services which require data centers for their hosting servers since they can't run on one server. The facilities take care of the temperature, humidity, power and connection backups in order to ensure the most effective and continuous operation of all web servers housed there. All data centers include 24/7 monitoring and limit the access to the hosting servers in order to ensure that the web servers are protected all the time. The quality of any Internet service you get usually depends not simply on the company you communicate with, but also on the data center they use.
