Top 10 Fastest Computers in 2012

IBM Sequoia

The list of fastest computers in 2012 according to their processing capabilities.

Fastest Computers

The fastest computers are commonly known as super computers. These computers are enormous, rare, expensive and mostly held for research and academic purposes. It won’t be surprising to learn, the leading super computers have powerful processing capacity and whopping calculation speed measured in PetaFlop/s (PetaFlop is a thousand trillion floating point operations per second).
