The fastest computer in the world (that isn't classified) is the Jaguar XT5 at the National Center for Computational Sciences. It has over 200,000 cores, in over 10,000 computer nodes. In consumes an area of space larger than a reasonably sized house.
According to the 11/2009 list, the fastest super computer on earth is Jaguar Cray XT5-HE Opteron Six Core 2.6 GHz with a fastest speed of 2331000 Giga Floating operations per second. It is situated at Oak Ridge National Laboratory located in Oak Ridge, Tennessee, near Knoxville USA.

i know that everyone say that acer is the 1st best computer then sony is the 2nd best computer then hp is the 3rd best computer then samsung is the 4th best computer then LG is the 5th best computer then compack is the 6th best computer there are so many types of computers i didnt say all go in google and see if you could find more types of computers
the most powerful computers are called supercomputers and there able to do trillions of calculations per second the fastest computer is called the BlueGene/L and it can do 360 trillion calculations per second
Currently (in 2012) the most powerful cluster computer is the K Computer, located in Japan. This computer uses Fujitsu infrastructure comprising many CPU cores and fast network transmission. It can perform around ten petaflops per second. Each petaflop is equivalent to one million billion (10^15) math operations.

When classified according to capacity, the computers can be classified into five groups. The five groups includes the super computers, the large computers, the medium sized computers, the mini computers and the micro computers.
