In total, Cern operates a network of six particle accelerators and a decelerator.
Cern is funded by 20 European member states, and is currently the workplace of 2600 full-time employees, as well as around 8,000 scientists and engineers.
Founded in 1954, Cern has a distinguished scientific pedigree. It has been home to three Nobel laureates, and it is the place where computer scientist Tim Berners-Lee invented the World Wide Web in 1989.
The scientific achievements at Cern have been profound for the scientific community, although the layperson may not recognise their significance.
In 1980, while working at Cern, Tim Berners-Lee wrote a program for storing information using random associations, which he called Enquire.
This formed the conceptual basis for the global hypertext project which Berners-Lee proposed in 1989, to be known as the World Wide Web.
WorldWideWeb was also the name of the hypertext browser that Berners-Lee created, along with the initial specifications of URIs, HTTP and HTML.
Cern is the home of the Large Hadron Collider (LHC), an enormous particle accelerator that smashes particles into each other at extremely high speeds.
The LHC has taken six and a half years to build, at a cost of £4.75bn. Located 100 metres underground, in the region between the Geneva airport and the nearby Jura mountains, the LCH uses a 27km long circular tunnel.
From an IT perspective, Cern's major challenge has been to put in place the technology to collect, store and analyse the data, and share it with the world.
As of August 2008, the world's biggest particle accelerator, the Large Hadron Collider (LHC), will begin hurling subatomic particles, called protons, around a 27km circular tunnel running beneath the Swiss-French border, before crashing them into each other.
For example, scientists believe they will learn more about the actual mass of particles, and about the nature of dark matter, and whether there are 26 dimensions, or just 12.
The 'Big Bang' project is an international initiative that will involve more than 2,000 physicists from 150 research institutions in more than 30 countries.
The IT department at Cern is creating the world's largest computing grid - known as the LHC Computing Grid - for the Big Bang project.
The LHC Computing Grid (LCG) went live in June 2008, pooling the processing power of around 100,000 CPUs worldwide.
It will process information at a rate of 1gbps, to cope with the massive outpouring of data that will come from the LHC particle accelerator.
As well as pioneering grid computing, Cern is also paving the way for large-scale intercontinental networking with a 10Gigabit wide area network (WAN).
Cern has extended database-clustering technology to enable a single database to run across a number of distributed computers.
The LCG database deployment project has set up a worldwide distributed database infrastructure for the LHC.
It will do this using a program called Oracle Streams to capture, filter and synchronise data stores worldwide.
As well as working with Oracle, IBM also worked with Cern to build a massive Linux-based storage system supplying many terrabytes of disk storage.
Grid computing is already being used by Google and Amazon, as well as banks like HSBC. It will have more applications in the financial sector as processing demand grows, predicts analyst firm Gartner.
Analysts have said financial firms will deal with gigabytes of data per second within the next five years. So the sorts of grid processing, networking and storage technologies that Cern is pioneering will soon become relevant to many technology users.
