TOP 10 inventors of all time

Computers, love them or hate them, we rely on them every day. But, have you ever stopped to think about who invented computers and how they came to dominate our lives?

So who invented the first computer and who can I blame for all those wasted hours? You might be surprised to learn that many computer pioneers struggled to get funding for their ideas and faced skepticism from their contemporaries. Early computers were actually people, not machines — it was a job title. The word dates back to It is an ancient-Geek, hand-powered mechanical device. Archeologists believe it was used to calculate eclipses and other astronomical events.

Due to its complexity, many speculate that it had several, less complex predecessors. Generally, these fulfilled a single purpose. From until his death in , he designed 3 computers , but never actually constructed any of them, due to lack of funding.

In Babbage started working on a Difference Engine its purpose was to compute polynomial functions. If completed it would have had some 25, parts, weighed 13, kg 15 short tons and been 2.

Between — Babbage created drawings for the Difference Engine No. Amazingly, it worked! It took 6 years to build, weighs The Analytical Engine , a later Babbage computer design, would have had a whopping bytes of memory! Punch cards were used as input, based on the Jacquard Loom punch card system , invented at the turn of the 19th century.

He saw mechanical computers as a way to remove error. As we all know, necessity is the mother of invention and never was that more true that during WW2!

During this period, electromechanical computer technology speed rocketed. Early electromechanical computers were a sort of hybrid between modern electrical computers and analog computers. Electric switches drove mechanical relays, although parts still wore out quickly, electrical switches could open and close around 1, times faster than mechanical ones, making electromechanical computers much, much faster.

At the time the Japanese also had an automated, torpedo firing computer on their submarines. However, it was not capable of tracking a target. In , Germany, Zuse began work on the Z1 : a mechanical calculator. It worked on a binary system and was fed paper tape. It was also pretty slow. However, with a little help from his friend Helmut Freier, an electrical engineer, this formed the basis of the Z2….

The Z2 was an electromechanical computer that was capable of slightly more varied functions. It took 0. It had a monitor, keyboard and a 21 inch, flatscreen!

The user could write and feed programs using a strip of film. The Colossus computer was a fully programmable, electronic, digital computer , developed to aid British codebreakers in decrypting German radio telegraphic traffic. Unlike modern computers, it was programmed with a series of switches and plugs. Given our reliance on computers today, it is hard for us to imagine, but Turing had an extremely hard time convincing his contemporaries of the importance of his work. Like so many early computer scientists he struggled to get the funding he needed.

Note: The Colossus computer is not to be confused with the Bombe: an electromechanical device, also designed by Turing and used to decode Enigma, in His work did not stop at the end of WW2! After the war, he worked at Manchester University where he played a key role in developing early computing technology and wrote several papers, that still define the way with think about computer science to this day. Although he might not be the man who invented computers, Turin is certainly the man who invented computer science!

It lacked many of the functionalities of modern computers; it was designed for one specialist task and was not Turing complete. It was fully reprogrammable and so, able to solve a complex number of problems. It could take several days to program because it was programmed via external switches and dials. The ENIAC took 20 seconds to complete its first calculation, a mechanical computer of the time would have taken 40 hours.

By the time it was decommissioned, in , it had been used to solve problems as diverse as wind tunnels, random number generators, and weather prediction.

The ENIAC contained 20, vacuum tubes, 7, crystal diodes, 1, relays, 70, resistors, 10, capacitors and 5,, hand-soldered joints.

The ENIAC consumed a staggering kW of electricity, which led to a rumor that whenever it was switched on, lights dimmed in Philadelphia. Several tubes needed replacing every day. Although relatively simplistic to other computers of the time, it was the first computer to store its program digitally not via wires and switches. Like the Machester Baby, it also used a stored program.

However, it did not run exclusively on transistors and contained several tubes in its clock. It was not, a commercial success. The computer was so successful that the company had to hire extra staff just to keep up with demand!

Because of the versatility of this design, several enterprising individuals designed upgrades that users could add to their model. The IBM was the first, commercially successful, portable computer. The IBM had a bit processor, took quarter-inch cartridge QIC magnetic tape drives and gave users the option to switch the screen between white on black and black on white. It was launched in Japan in and released internationally in It weighed just 1.

It even featured a built-in, calculator-style roll printer. Although maybe a little strange to look at, the first flip-form laptop , was the Dulmont Magnum, released in Australia in — The Dulmont Magnum came with a word processor, spreadsheet, telecommunications, file manager, appointment manager and an 8 x 80 character LCD screen. Steve Jobs unveiled the first Macintosh in The Macintosh was built without a cooling fan, to keep the computer quite.

However, this caused the computer to overheat, resulting in many component failures. The HP was one of the earliest commercialized touchscreen computers. A series of vertical and horizontal infrared light beams crossed just in front of the screen. Touching the screen would break the infrared and place the cursor at the desired location. So, who invented computers? Was it Babbage, Turin, Zuse or some ancient civilization?

Let me know what you think in the comments below. Well done article. The design of the Altair was very basic. Username or Email Address. Remember Me. Tech Trends. Rose Barfield , 6 months ago 1 13 min read. TL;DR Who invented computers? Originally computers were people — it was a job title.

The first computer was invented by Charles Babbage but was not built until ! Alan Turing invented computer science. The first Mac was debuted in She loves finding out how things work, taking them apart, and hopefully, putting them back together again.

List of Founders and Inventors Related to Computer

Computer science , the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software , and their uses for processing information. The discipline of computer science includes the study of algorithms and data structures, computer and network design, modeling data and information processes, and artificial intelligence. Computer science draws some of its foundations from mathematics and engineering and therefore incorporates techniques from areas such as queueing theory, probability and statistics , and electronic circuit design. Computer science also makes heavy use of hypothesis testing and experimentation during the conceptualization, design, measurement, and refinement of new algorithms, information structures, and computer architectures. Computer science is the study of computers and computing as well as their theoretical and practical applications.
