Cast your mind back to a time when computers were 30 tons in weight and consumed 150 kilowatts of power. Does this seem like reality? But in fact during the events of Word War II, the first ever computer was built by Mauchly and Eckert and was activated 67 years ago, helping and assisting the US army.
The ENIAC (Electronic Numerical Integrator And Computer), was a reprogrammable machine that performed initial calculations for H-Bombs, and it was used to prepare artillery shell trajectory tables and perform other military and scientific calculations.
It contained 19,000 vacuum tubes, 6000 switches and it could add 5,000 numbers in a second. I am sitting here trying to contemplate and comprehend how far we’ve come from a enormous computer that took up the space of an entire room, to a small and powerful box that we are able to hold in the palm of our hands. It was powered in 1946 and deactivated in 1955, now components of this ground breaking computer have been distributed across the world.
So how have computers evolved?
Well in my opinion, that we have come a long way from what we have designed in computer technology. When the ENIAC was created, it started to inspire many computer scientists around the world, that pursued them to create and upgrade the computer.
The ENIAC must have used a lot of electricity, due to it being so big, but nowadays, our computers such as laptops, iPhone’s and Macs, are now more smaller and more powerful.
We have come a long way with computers from a large mechanical brain that took up an entire room, from a device that is small in size, but has a knowledgeable mind.
I wonder what the next the step is to upgrading computers. I am excited to what the future holds.
