Computers are the most phenomenal of man’s inventions. They have been easing our lives for many decades now. They are present in our lives now. It has become a very irreplaceable thing in all our lives. Computers have dominated all the aspects of our lives. It has become an inevitable part of our living times. We even have computers to do simple functions of our lives. We have computers that can replace humans. Computer has inhibited every part of our life. Computer resides in every house, everywhere.
We people cannot imagine a life without computers nowadays. We wouldn’t know what to do without our computers to look into! But can you imagine a time in the past where all these were considered futuristic and nerdy? Can you imagine a time when all these technologies were not there and people actually talked to each other – face to face and had time for each other?
Before 1943 there wasn’t a thing called computers, at least not in material! World’s first computer ENIAC was first put into use in 1943. ENIAC (Electronic Numerical Integrator and Computer) was used to calculate artillery firing tables. An ENIAC has 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, 6000 manual switches, 5 million soldiered joints and used 160 kWhs of electrical power to work.
ENIAC was invented in the University of Pennsylvania. It is said that when ENIAC is in action, houses around the neighbourhood had electricity problems. It was literally catastrophic with ENIAC. ENIAC had a large consumption of electricity. It also occupied a large amount of place. It almost covered 3 floors in University of Pennsylvania.
Along with all the paraphernalia, it has to have all the current it needs and as I said its consumption is really very high. As the technology began becoming efficient, the size of the machines began decreasing and even their efficiency began increasing.
As the revolution started, in 1965 Gordon.E.Moore coined the Moore’s law. It states that the number of transistors that are used in a computer doubles every 2 years. It wasn’t a law when he said it and was merely a prediction, an observation that he foresees. Fortunately for him it became true from the year 1965 to 2013. From 2013 the upgradation began every 3 years. In 2013 there were 3 million more transistors in use than there were in 1965.
The Apple A8 xProcessor of 2014 has 3 billion processors which renders it powerful enough to compete with the supercomputers made in 1990s. It means it took us 20 years of exponential chip development to reach this type of efficiency in mobile devices.
Back when ENIAC was the buzz of the day, transistors, that we talk about today, weren’t anywhere in the horizon. There were vacuum tubes. When an ENIAC was working, vacuum tubes constantly came out and the users had to stick it in. but in our latest gadgets powered by dual core Itanium 2 has 1,700,000,000 transistors put into 596 mm².
As the technology progresses we look for other realms that we can conquer. Some of the most recent inventions are Protein Computers, Graphene Computers, and DNA Computers etc. Scientists have already been engaging themselves in the production of these computers. With such technologies in line, one need not be cautious of any apocalypse, as technology is the case.
As technologies build up, the energies used have been evolving and getting smaller day by day. ENIAC had used watts of electricity and energy while some of the computers and technologies at work today don’t need half of the energy that ENIAC used.
In the yonder past, no one not even the brightest of scientists then thought that the technology would be so developed. Once Bill Gates, the greatest tech revolutionary we have ever seen, had said that 640 Kb of RAM is all that anyone would need at any point of time.
Such was the days and look at the change we have witnessed in the technology front – now that’s vast, huge and exponential. Best is yet to be!
