The History of Computers
From primitive abaci to lab tops and calculators, the computer has evolved through time to become the essential part of our technocratic society. The development of the computer has shaped the way technology and science is viewed in different cultures around the world. The connotation of what a computer is nowadays brings to mind a monitor, keyboard, processor and its other electronic components; however, that is not how things have always been. From the Chinese using abaci to count, to the Druids' usage of stones to follow the seasonal changes, to the Europeans using Pascalines and calculators to work out mathematical problems the concept of the computer has been around for hundreds of years (Hoyle). Therefore, the history of computers is important to observe not only for the influence it brought to our culture, but the progress it has made through time.
The history of modern computers has been influenced by the earlier advancement of primordial technology. The abacus developed in circa 500 B.C for example, used pebbles, rocks, beads, or shells to keep track of the counters numbers.
Furthermore, "the abacus was man's first attempt at automating the counting process" (Hoyle). In addition, the Pascaline, invented and built by a French philosopher and mathematician Blaise Pascal, was the first mathematical adding machine (Long 54). The Pascaline was a gear-driven machine that allowed the user to calculate answers without doing arithmetic (Hoyle). In addition to the abacus and the Pascaline, Babbage's Folly, also known as the difference machine, "hastened the development of computers. [and] advanced the state of computational hardware" (Long 55). This engine, designed by the Cambridge professor Charles Babbage, could do any of the basic functions of mathematics: adding, subtracting, multiplying, and division in series at a "rate of 60 additions per minute" (55) could all be accomplished with minimal effort. All of these ideas and concepts helped pave the way for innovators to design what we now view as the modern-day computer.
It took certain people to utilize these primitive forms of computing data to create real technologically advanced machines. Such a person, for example, was the professor Dr.
Try to imagine life without calculators and how difficult it would be to solve a mathematical problem. However, Charles Babbage is the person to thank and be grateful that we do. Charles Babbage is the inventor of the Difference Engine as well as the Analytical Engine. These inventions were made to calculate different math problems with accuracy and prevent human beings from making errors when solving a math problem. In the following paragraphs you will learn about Charles Babbage early life, educational background, and how his inventions are relevant to today.
The subject of this term paper will be about computers in the 1950’s. The divisions that will be covered are; the types of computers there were, the memory capacity of computers, the programming languages of that time, and the uses of the computers for that time. Information will be gathered from the Internet, from books, and from magazines, and from the encyclopedia.
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
Computers are a magnificent feat of technology. They have grown from simple calculators to machines with many functions and abilities. Computers have become so common that almost every home has at least one computer, and schools find them a good source for information and education for their students (Hafner, Katie, unknown). Computers have created new careers and eliminated others and have left a huge impact on our society. The invention of the computer has greatly affected the arts, the business world, and society and history in many different areas, but to understand how great these changes are, it is necessary to take a look at the origins of the computer.
...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.
Pascal programming language was designed in 1968, and published in 1970. It is a small and efficient language intended to encourage good programming practices using structured programming and data structuring. Pascal was developed by Niklaus Wirth. The language was named in honor of the French mathematician and philosopher Blaise Pascal. In 1641, Pascal created the first arithmetical machine. Some say it was the first computer. Wirth improved the instrument eight years later. In 1650, Pascal left geometry and physics, and started his focus towards religious studies. A generation of students used Pascal as an introduction language in undergraduate courses. Types of Pascal have also frequently been used for everything from research projects to PC games. Niklaus Wirth reports that a first attempt to merge it in Fortran in 1969 was unsuccessful because of Fortran's lack of complex data structures. The second attempt was developed in the Pascal language itself and was operational by mid-1970. A generation of students used Pascal as an introductory language in undergraduate courses. Pascal, in its original form, is a Procedural language and includes the traditional like control structures with reserved words such as IF, THEN, ELSE, WHILE, FOR, and so on. However, Pascal has many data structuring and other ideas which were not included in the original, like type definitions, records, pointers, enumerations, and sets. The earliest computers were programmed in machine code. This type of programming is time consuming and error prone, as well as very difficult to change and understand. Programming is a time-consuming a process. More advanced languages were developed to resolve this problem. High level languages include a set of instruction...
Houghton. A Brief Timeline in the History of Computers. Western Carolina University Retrieved January 30th 2014 from Western Carolina University:
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.
Technology continued to prosper in the computer world into the nineteenth century. A major figure during this time is Charles Babbage, designed the idea of the Difference Engine in the year 1820. It was a calculating machine designed to tabulate the results of mathematical functions (Evans, 38). Babbage, however, never completed this invention because he came up with a newer creation in which he named the Analytical Engine. This computer was expected to solve “any mathematical problem” (Triumph, 2). It relied on the punch card input. The machine was never actually finished by Babbage, and today Herman Hollerith has been credited with the fabrication of the punch card tabulating machine.
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.
Known as the “father of computing”, Charles Babbage has inspired many scientists and engineers with his wonderful inventions. His goal was to create a machine that would reduce the possibility of human error in making mathematical calculations. In addition to inventing an early form of the calculator, Babbage also invented the cowcatcher and the first speedometer for trains. Babbage said, “At each increase of knowledge, as well as on the contrivance of every new tool, human labor becomes abridged.” This could possibly mean that he was on his quest for knowledge to help reduce the amount of human labor needed in daily processes. Babbage could only have achieved those great feats because of the fine education he received during his childhood.
