One of the first few inventions of a computing device was the abacus, which was developed by the Babylonians in the 4th century BC. Other concepts that contributed to the development of computers were the adoption of Arabic numerals and the concept of zero. Then a while later came the invention of mechanical calculators by Wilhelm Schickard and Blaise Pascal in the 17th century. Then, in the 19th century, Charles Babbage created a steam-powered “Difference Engine” which aimed to calculate astronomical tables. But since it was not successful, he converted the idea into the creation of Analytical Engine, which is designed to solve all sorts of math problems.
This idea was followed by Augusta Ada Byron where her writings included descriptions about ways computers can work, plus the concepts of data analysis and memory. Then there was George Boole, who was the man behind Boolean algebra. With the ideas pooled together from Babbage, Pascal, Byron and Boole, it was foreseen that it would be possible to create machines that would be able to store and analyse data.
Then electricity zapped into being in the 1940s which allowed for Konrad Zuse’s invention of the programmable calculator, and the invention of transistors by Bell Telephone. There were other inventions that contribute to parts of the modern computer, but a notable one one was by John von Neumann in his idea of stored program. Later in 1949, the Electronic Storage Delay Automatic Calculator was created and was the first computer that could store programs.
After that, many developers tried to come up with other computers, creating companies such like Xerox, Intel and Fairfield in the late 60s and early 70s, and names like Bill Gates, Steve Jobs and Steve Wozniak became popular for their inventions of PCs and Apple 1. With many contributions from various parties, it is impossible to pinpoint exactly who invented the computer.
Launch Of Personal Computers
The very first units of personal computers were manufactured and initially sold via mail-order as a result of the encouragement of a friend who coincidentally was an editor of a well-known technology magazine. They were quite costly, too, amounting to $400 per unit but they sold like hot cakes. Due to the overwhelming respond from the public, other companies were inspired to do the same thing.
Two engineers from the now world-renowned company named Steven Jobs and Stephen Wozniak invented the world’s first ever homemade microprocessor computing the machine. They were able to successfully create this while working in the garage of Stephen Job’s parents. As a hobby, they started to mass produce these computers. Being technology enthusiasts, they started the company which was very successful and they also eventually released the second version of the first computer which was considered the worlds’ first personal computer. The very first personal computers cost a fortune which made it difficult to purchase.
It is so fascinating to know the history of the computer it’s constant evolution. Today, personal computers can be customised depending on your preference and needs – for work, leisure, studies or just gaming.
Invention of the Computer Mouse
Every invention that man brings to the table is often stoked by good intentions. When computers were invented, they were giant machines needing extensive room and power to crunch through complex formulas and now they are portable and beautiful. The evolution of the computer is truly inspiring.
Douglas Engelbart was acknowledged as the man who invented the computer mouse prototype in the mid 60’s. Albeit crude in design, the nature of the device was to track the X-Y position of an indicator on a display system. Similar to reading graphs and maps, wherever the axes intersected, that marked the spot. The device was appropriately coined due to its semblance to a rodent with an attached tail. A decade on, a working partner of Engelbart by the name of William English improved the design to include a ball within the device. With greater flexibility in motion and rotation, this was the forefather of the roller-ball mice to come.
The design for the mechanical mouse continued to change with each inventor seeking ways to tweak and add better features. Moving parts were synonymous with wear and tear. Coupled with a lack of maintenance, these devices were prone to getting stuck and indicating incorrect positions. It seemed timely to reduce reliance on them and move on to better devices.
Richard Lyon and Steve Kirsh who invented the computer mouse which used light to detect movement joined the ranks. The optical mouse became the rage of the ages as it had no moving parts yet was accurate in determining the device’s position on the screen.
Their invention, however, is not the end of the mouse tale. From a single button, more were added to the limited surface, sometimes confounding users with the myriad of buttons to click and roll. The mechanical mouse is now obsolete and has joined the ranks of museum residents. Newer versions based on 3D are also on the horizon.
The Continued Innovation Of Computers
Today, computers are known worldwide and a source of entertainment and business. We use computers to share and receive critical information. They are small enough to carry in the palm of our hand and large enough to help fly airplanes. Computers are relied upon for a variety of things. We undeniably need computers. From emergency room vitals to banking information, they provide us with critical information. New products emerge each day as computers continue to become more and more advanced. Within just a few years, the computer you are using today will be completely outdated. Computers and other electronic devices are being made out of better and more advanced materials.
