Evolution of Computers
The essence of a computer is in its ability to make complicated calculations in lightning fast times. For this reason, many agree that the first computer was invented 4,000 years ago with the advent of the abacus.
Designed to help humans calculate, the abacus was the main computer in society for an astonishing period.
In fact, it was not until 1951 that the first modern computer was invented. The Harwell computer or WITCH (Wolverhampton Instrument for Teaching Computing from Harwell) could store data and perform some basic arithmetic.
The next step in the evolution of computing occurred in 1976 when Steve Wozniak created the Apple I, which was quickly followed by the Apple II in 1977.
These were among the first commercially available computers, although their functionality would be unrecognizable in comparison to today’s fancy Macs.
In 1981, IBM entered the computer market with the IBM PC. This became the prototype for the design and specification of many PCs that followed.
In 1990, Windows created its 3.0 version which formed the basis for subsequent Windows versions and in 1999 the release of the iMac led to Apple becoming one of the most fashionable brands in the world.
From this moment onwards, computers became slimmer, faster, and with better capacity, leading to the plethora of laptops, PCs, and Macs on the market today.
Evolution of the Cell Phone
Cell phones are almost as essential to the modern human as air, food, and water. In all probability, you are reading this article from your cell phone right now. We may take this amazing function or granted today, but only 15 years ago the ability to access the internet on your cell phone was considered futuristic and almost unimaginable.
Just watch an old episode of Friends or Seinfeld to see how things were not so long ago. Cell phones have evolved so quickly it is difficult at times to keep up.
The first cell phones that were commercially available appeared on the scene in the 1970s. These “brick” phones were incredibly futuristic at the time. Ask anyone over the age of 50, and they will recount to you the time when they first saw or heard of a cell phone and how incredible it was.
Today, however, cell phones can perform multiple tasks. If you went to school before the year 2000, you might remember your mathematics teacher telling you to show how you worked out sums on your paper as you “won’t have access to a calculator everywhere you go.”
Well, you can now call that maths teacher on your cell phone and work out any equation while on the phone with them, then tweet the answer to thousands of people while listening to your favorite song and taking a video of your cat falling over.
The point is cell phones are an amazing example of rapid advances in gizmos. The future of cell phones is undeniably exciting, and in 30 years’ time, we are likely to see smaller and smaller cell phones with even more functionality.
