Integrated circuit (IC) is a tiny device that controls electric signals in such electronic equipments as computers and T.V sets. Many integrated circuits contain thousands of electronic parts on a paper - thin chip of silicon. These parts include capacitors, diodes, all in a very small, compact space.

CPU speed is measured with the processors speed which is measured in MIPS (Million Instructions Per Second), Flops (Floating-point operations per second) and CPU clock speed (usually measured in gigahertz). 

The longest venomous snake The King Cobra is the only snake that build nests for its eggs.

Mercator projection type of maps are best suited for maritime navigations.

Calculation of molar mass of HNO3:

Atomic masses of H, N, O are 1, 14, 16 respectively

Now the molar mass of HNO3 is

HNO3 = 1X1 + 1X14 + 3X16

= 1 + 14 + 48

= 63 g/mol or amu.
