Down Arrow Transcript Of The Interview - Part 2

Down Arrow 3.0 - Origins of Computers.

Hema : Maheshji, we will not find anyone today who does not have any practical knowledge about the computer.

Many people know what a computer is and have proper understanding of its use, but do not know of its origin and where it was invented and also when it came to India.

It is hardly known to all but a few people. We will move ahead, friends, with a lot of information which in today's world is important. Sir, please tell us of its origin.

MK : After World War II, in 1946, two scientists from University of Pennsylvania made a computer called ENIAC (Electronic Numerical Integrator And Calculator).

This weighed 30,000 kilograms. Its size was 1,500 sq. feet, which is the size of a large apartment flat.

It had 18,500 Parts and 6,000 wires through which an army of engineers would operate on the same. Its electric consumption was equal to that of 4,000 light bulbs.


Hema : So it was quite big in size as well as in use.

MK : Yes. This computer was made at that time, to help guide the artillery guns and land-based guns to fire them in a specific direction.

Before this computer, this was done manually by a mathematician.

It involved 200 calculations, taking into consideration the temperature, the wind's direction and velocity.

It used to take this trained mathematician between 7-20 hours to complete the same.

The ENIAC made solely for this purpose, however completed this calculation in an astonishing 30 seconds.

Hema : Only 30 seconds ?

MK : Yes, at that time this machine was so powerful that the nuclear calculations which would have taken 100 years to do manually were done by ENIAC only in 2 hours time.

After the 2nd World War ended in 1945, the US computer industry saw many technological advances with each passing generation.

Down Arrow 4.0 - Moore's law and it's implications for the IT industry.

MK : In 1975, a US Scientist Gordon Moore invented the Microprocessor chip which is the computer's brain. It is a very small 2 inches by 2 inches component which co-ordinates the functioning of the entire computer.

Moore formulated what is known in the computer industry as 'Moore's Law'.

He said that the number of parts that could fit on a microprocessor would double every 12 - 18 months.

Today, if a microprocessor has 1,00,000 parts; in about 18 months, it will have 2,00,000 parts. In 3 years, it will have 4,00,000 parts and so on.

Moore's law has successfully prevailed over the last 25 years and it is predicted to prevail for another 10 years.

Today the normal desktop computer that we see will be replaced by ones which will be faster and smaller in size.

It's speeds and efficiency will increase by a 100 times within a decade.
