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.
England, birthplace of Shakespeare and The Beatles, is a country in the British Isles bordering Scotland and Wales. The capital, London, on the River Thames, is home of Parliament, Big Ben and the 11th-century Tower of London. It's also a multicultural, modern hub for the arts and business. Other large cities are Manchester, Birmingham, Liverpool, Bristol and the university centres of Oxford and Cambridge.
