The Earlier computing devices have measuring units that will not only surprise you but infact give a shocking preview of history of computing. It will not only give the importance of women in the earlier computing but also give the vary important fact that women contributed a major non told share in the calculation dynamics.

Engineers used to measure the earlier computing devices in **Kilo-Girls** , a unit roughly equal to the calculating ability of the thousand women.

When the first super computer was invented in 1965 , a larger unit is required to determine the computation power of the machines. Therefore the Flops came into this universe. Flops are termed as floating point operations per seconds. In 1946 , ENIAC, the first non-super computer processed about 500 Flops. Today super-computer crunches peta FLOPS which is equivalent to 1000 trillion computations.

As the time moves on the shrinking of transistor size allows the accumulation of more electronics that can be fitted in a space. But processing so much data requires a complex design , very good and intricate cooling systems. Also the suitable interface for humans to operate and access the hardware. Lets look at some of the important super computers and their uses.

**CDC 6600** is used in cern . It helps the cern engineers to rapidly sift approx 3 million cern’s experimental research images per year.

**ASCI RED** used by the united states , helped us to model the nuclear weapons capabilities so that it can avoid the underground test.

**IBM Sequoia** is enabling the Stanford engineers to study the jet engines by using its more than 1 million cores.

**Sunway TaihuLight** with its processing speed 93 peta Flops by trading the slower memory for higher energy efficiency.
