A data center or data centre is a facility used to house computer systems and associated components, such as telecommunications and storage systems.
Data centers are simply centralized locations where computing and networking equipment is concentrated for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data. They have existed in one form or another since the advent of computers.
In the days of the room-sized behemoths that were our early computers, a data center might have had one supercomputer. As equipment got smaller and cheaper, and data processing needs began to increase -- and they have increased exponentially -- we started networking multiple servers (the industrial counterparts to our home computers) together to increase processing power. We connect them to communication networks so that people can access them, or the information on them, remotely. Large numbers of these clustered servers and related equipment can be housed in a room, an entire building or groups of buildings. Today's data center is likely to have thousands of very powerful and very small servers running 24/7.
Reading is a large town on the Thames and Kennet rivers in southern England. It’s known for the annual Reading Festival, an outdoor rock music event. Shops and riverside restaurants dot the town centre. The Reading Museum contains exhibits on the town’s history and displays a Victorian replica of the Bayeux Tapestry. The ruins of the 12th-century Reading Abbey lie beside Forbury Gardens, a Victorian formal garden.
