History of Computers
When you think about the origins of the electronic digital computer, what scientists’ names come to mind? Many historians give the credit to the American scientists J. Presper Eckert and John W. Mauchy. They built their Electronic Numerical Integrator and Computer (ENIAC) during World War II. These two scientists founded the first private computer systems company. Although most people recognize Eckert and Mauchy as the persons accountable for the computer industry, historians are beginning to recognize a more unfamiliar history of the computer, its roots in the military establishment. (Meyers)
The birth of the abacus was the beginning of computer history. The abacus is a wooden rack that holds two horizontal wires with beads strung on them. Moving the beads on the abacus can solve regular arithmetic problems. Thomas of Colmar developed the desktop calculator. While great advances were made in mathematical physics between 1850 and 1900, mechanical engineering and science began to make important advances in several areas by the time WWI broke out in 1939.
The Navy was particularly interested in the development of advanced technology beginning in World War I. “Important advances in naval warfare, including the use of mechanical directors and computers for fire control, the use of radio for communication across great distances, and the development of the attack submarine posed new technical problems for strategists.” (Flamm) A consulting board was set up in order to screen the proposals of outside inventors. The board also set up a laboratory to work on the problems of antisubmarine warfare, and eventually the Naval Research Laboratory was then established in 1923. The development of RADAR, radio communications, and the interception of encrypted enemy communications traffic were all supported by the Navy’s postwar research efforts. “Because signals transmitted by radio could be intercepted much more easily than communications over land lines, cryptanalysis became an economic means of acquiring intelligence about the intentions of foreign, especially naval, military forces.” (Flamm)
During the 1930s, the Navy supported substantial work on servomechanisms at MIT. The analog computers were developed after Navy officers enrolled as graduate students in MIT’s Servomechanism Laboratory.
I learned many things from the different naval experiences that these men were confronted with, but what had intrigued me was the vast majority of naval technology used during the war and its particular job as well as who had control over the vast majority of it. The future Fleet Admirals were appointed certain jobs, and were each given different naval ships they had to command with knowledge, and each played a role in the Allied victory in the sea. Before the war each officer held on a variety of vessels, battleships, submarines, aircraft carriers, and how the development of each type of vessel influenced the course of naval warfare. While battleships had reigned as the most reliable and preferred vessel of the seas, their supremacy was soon challenged by the uprising of the carrier. Leahy was the oldest of the four who had clung to his view of the vessel he felt was reliable and he believed strongly in the battleship's power. Nimitz was an advocate of the submarine as a strategic and very effective weapon as it could be evasive to vessels on the sea’s surface. Halsey was a devotee of the destroyer but eventually came to under...
Over the year and a half between Pearl Harbor and Midway the United States made headway with various technological and military advantages. One of the most important of which was the code breaking efforts of Commander Joseph J. Rochefort Jr. “Most of the U.S’s information [on Japan] came from Rochefort. R...
People have been in awe of computers since they were first invented. At first scientist said that computers would only be for government usage only. “Then when the scientists saw the potential computers had, scientist then predicted that by 1990 computers may one day invade the home of just about ever citizen in the world” (“History” Internet), the scientists were slightly wrong, because by 1990 computers were just beginning to catch on. Then a few years later when scientists when to major corporations to get help with a special project, the corporations said no, because computers would just be a fad and they wouldn’t make much money off of it. “By definition Abacus is the first computer (the proper definition of a computer is one who or that which computes) ever invented” (Internet).
In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.
When World War II broke out in 1939 the United States was severely technologically disabled. There existed almost nothing in the way of mathematical innovations that had been integrated into military use. Therefore, the government placed great emphasis on the development of electronic technology that could be used in battle. Although it began as a simple computer that would aid the army in computing firing tables for artillery, what eventually was the result was the ENIAC (Electronic Numerical Integrator and Computer). Before the ENIAC it took over 20 hours for a skilled mathematician to complete a single computation for a firing situation. When the ENIAC was completed and unveiled to the public on Valentine’s Day in 1946 it could complete such a complex problem in 30 seconds. The ENIAC was used quite often by the military but never contributed any spectacular or necessary data. The main significance of the ENIAC was that it was an incredible achievement in the field of computer science and can be considered the first digital and per...
Mark I. It was actually a electromechanical calculation. It is said that this was the first potentially computers. In 1951 Remington Rand’s came out with the UNIVAC it began
...ere are gears used to select which numbers you want. Though Charles Babbage will always be credited with making the first “true” computer, and Bill Gates with popularizing it, Blaise Pascal will always have a place among the first true innovator of the computer. There is even a programming language called Pascal or Object Pascal which is an early computer program.
Computer engineering started about 5,000 years ago in China when they invented the abacus. The abacus is a manual calculator in which you move beads back and forth on rods to add or subtract. Other inventors of simple computers include Blaise Pascal who came up with the arithmetic machine for his father’s work. Also Charles Babbage produced the Analytical Engine, which combined math calculations from one problem and applied it to solve other complex problems. The Analytical Engine is similar to today’s computers.
"Technology is like fish. The longer it stays on the shelf, the less desirable it becomes." (1) Since the dawn of computers, there has always been a want for a faster, better technology. These needs can be provided for quickly, but become obsolete even quicker. In 1981, the first "true portable computer", the Osborne 1 was introduced by the Osborne Computer Corporation. (2) This computer revolutionized the way that computers were used and introduced a brand new working opportunity.
We have the microprocessor to thank for all of our consumer electronic devices, because without them, our devices would be much larger. Microprocessors are the feat of generations of research and development. Microprocessors were invented in 1972 by Intel Corporation and have made it so that computers could shrink to the sizes we know today. Before, computers took a room because the transistors or vacuum tubes were individual components. Microprocessors unified the technology on one chip while reducing the costs. Microprocessor technology has been the most important revolution in the computer industry in the past forty years, as microprocessors have allowed our consumer electronics to exist.
The First Generation of Computers The first generation of computers, beginning around the end of World War 2, and continuing until around the year 1957, included computers that used vacuum tubes, drum memories, and programming in machine code. Computers at that time where mammoth machines that did not have the power our present day desktop microcomputers. In 1950, the first real-time, interactive computer was completed by a design team at MIT. The "Whirlwind Computer," as it was called, was a revamped U.S. Navy project for developing an aircraft simulator.
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations as multiplying, dividing, taking the square root.
