Evolution of Calculator

Evolution of Calculator

The world is continuously experiencing changes that are either good, bad or neutral. The categorisation of these aspects of changes is not as important as their thorough understanding. There are certain unfathomable oceans of strange and dangerous facts extremely hard to decode for a normal human being with limited knowledge and experience.

We have continuously been exploiting the resources for merely our benefits ignoring the consequences waiting ahead of us. We are the generation that has seen drastic changes and dynamic reforms in societies. We have seen how difficult our days used to be as compared to that of today. Our struggle with calculation led us to many inventions like the abacus and other calculating devices.

We are not unaware of a legend about a mad scientist named Archimedes who devised a unique strategy to calculate and measure that still prevails.

We have a very strange and stiff history on the evolution of calculation and calculating devices. With hours slipping into days, days slipping into months, months slipping into years and decades, we kept coming up with innovations and ideas according to our needs and comforts.

Perfectly said by an ancient Greek philosopher Plato, “Necessity is the mother of invention” which still holds ground today as firmly as it used to. The only necessity is the reason behind the evolution of calculating devices from the abacus, a hand-operated device used to calculate in around 2000 B.C. to calculators like ti-84 calculator online.


Since time immemorial calculators are considered to be people’s best friend. Calculators have significantly undergone facelifts over the years but their fundamentals are still similar to that of our ancestors.

There have been times in history when calculators experienced saturation in terms of physical complexities but were saved and redeveloped with the advent of the internet which led to the creations like ti- 84 calculator online.

There are varieties of calculators as per our requirements. Different types of calculators are available to serve the vast majority of people like students, accountants, businessman, scientists, engineers and professionals.

Our Mobile phones too have calculators which are frequently used for perfection in calculations on a daily basis. Small scale businessmen prefer physical calculator to perform basic accounts for accuracy.

Our history is extremely rich, full of anecdotes and lessons that are continually being passed on from generation to generation. These anecdotes are humorous, informative and entertaining at the same time.

I have always struggled with calculations as we were prohibited from using calculators by teachers and parents. I personally hated this part the most. Long calculations seemed to me like mountains which are the hardest to climb. The numbers were like enemies ready to take me down.

But the scenario is completely changed now. Students are allowed to take the calculators to the examination halls.

I am happy about them being allowed to use one but feel sorry for them at the same time.

Using calculators to perform simple calculation will make them prone to dumbness and reduce the strength of their brain. I would suggest them to refrain from using calculators for minor calculations and try to improve upon the mental capacity.

It has made it extremely easy for people to connect to the internet and more and more people are actually getting connected to the internet because of WiFi. One of the greatest usefulness of the WiFi technology is that people can easily switch between different networks without having to worry about wires or cables.

WiFi Hotspots

It is the area around a WiFi source that connects computers and devices to the WiFi network. WiFi hotspots can be found in places like offices, cafes and even at homes.

The limitations of WiFi

Like with every good thing in the world of technology, there are some disadvantages of the WiFi technology. One of the major limitations of the WiFi technology is that the connection radius of the network is not more than some dozens of feet. The intensity of the WiFi signal gets reduced when the device or computer is placed further away from the source of the network. Once you are beyond 20 to 25 meters, you are outside the coverage radius.

Another major disadvantage of using WiFi, especially in public places is the risk of your devices getting hacked. Using WiFi in such places can risk the leakage of your personal data and financial info such as online banking passwords.
