DEFINATION of COMPUTER.. History of Computer.. First Inventer of Computer DEFINATION OF COMPUTER.. 1:A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. 2: An electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program. History of computer.. The history of computers starts out about 2000 years ago, at the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around, according to programming rules memorized by the user, all regular arithmetic problems can be done. Another important invention around the same time was the Astrolabe, used for navigation. Blaise Pascal is usually credited for building the first digital computer in 1642. It added numbers entered with dials and was made to help his father, a tax collector. In 1671, Gottfried Wilhelm von Leibniz invented a computer that was built in 1694. It could add, and, after changing some things around, multiply. Leibniz invented a special stepped gear mechanism for introducing the addend digits, and this is still being used. The prototypes made by Pascal and Leibniz were not used in many places, and considered weird until a little more than a century later, when Thomas of Colmar (A.K.A. Charles Xavier Thomas) created the first successful mechanical calculator that could add, subtract, multiply, and divide. A lot of improved desktop calculators by many inventors followed, so that by about 1890, the range of improvements included: • Accumulation of partial results • Storage and automatic reentry of past results (A memory function) • Printing of the results Each of these required manual installation. These improvements were mainly made for commercial users, and not for the needs of science. First inventer of computer.. Many say the first computer is the "difference engine." The first of these devices was conceived in 1786 by J.H. Müller. It was never built. Difference engines were forgotten and then rediscovered in 1822 by Englishman Charles Babbage..who is known as "the father of the Computer". This machine used the decimal numbers system and was powered by cranking a handle. The British government first financed the project but then later cut off support. Babbage went on to design his much more general analytical engine but later returned and produced an improved design (his "Difference Engine No. 2") between 1834 and 1869. Still others will say the abacus is the first computer. They were invented by the Chinese between 2600 BC and 300 BC is considered as the first computer ever. Abacus was used by the merchants and Clerks in China. Charles Babbage invented the concept of a programmable computer in about 1856. It partly depends on what you mean by "computer", but the earliest claim is that Charles Babbage invented the first programmable computer in 1822. The machine was called a "difference engine" and it was intended to generate mathematical tables. This machine contained 25,000 parts and weighed 15 tons. Babbage followed this with a "difference engine 2" which, although well funded, was never completed. Babbage also designed a printer to go along with the computer, but this also was never completed. In 1989- 1991, the London science museum made a difference engine 2 and printer from Babbage's design. Both worked perfectly. Benefits of computer.. Computers play a huge part in many all of our lives in one way or another. They have many purposes and are used in various types of environments, such as medical facilities, government offices, and many households. Using a computer, one can remain connected to the world through Internet. Internet is a network of computers that communicates via the Internet Protocol Suite (TCP/IP). The World Wide Web (WWW) or simply web is a huge resource of information that can be accessed via the Internet. To mention a few of the resources, there are electronic mail (e-mail), file transferring and sharing, online chat and gaming. The Internet allows people from around the world to share knowledge, ideas and experiences in any field. E-mail is a method of communication used globally and is provided with a system of creating, storing and forwarding mails. It may consist of text messages with attachments of audio-visual clips. One can also download or upload files using the Internet. There are also facilities like online chatting available on the Internet. As compared to telephonic conversation, both e-mail and online chat are cost saving. Online gaming is another important resource of the WWW. Many online games are available, which are of common interest for any age group. In addition, one can read current news, check weather conditions, plan vacations and make hotel and travel reservations, find out about diseases and treatment methods, conduct transactions, learn about specific countries and their cultures, seek jobs, buy products, etc via the Internet. Nowadays, computers are widely used for education and training purposes. In schools, computer education has been made compulsory to spread awareness about computers. As a matter of fact, computers have become a learning tool for children. Also, there are many universities that provide online degrees, which is very advantageous for those people staying in the remote areas and for the disabled. In fact, online education is one of the most flexible and convenient forms of learning. One can take the benefit of such online degree programs staying at home without the need of relocation. Computers are also used for training purposes. Many companies use them to train their staffs. Computers are making so many things possible. Without computer technology everything would take a lot slower to perform and everyday life would be less productive. That’s why I said that computer technology has many benefits..

  • Analytical Engine, 1838 ALLAN G
    Charles Babbage’s Analytical Engine, 1838 ALLAN G. BROMLEY Charles Babbage commenced work on the design of the Analytical Engine in 1834 following the collapse of the project to build the Difference Engine. His ideas evolved rapidly, and by 1838 most of the important concepts used in his later designs were established. This paper introduces the design of the Analytical Engine as it stood in early 1838, concentrating on the overall functional organization of the mill (or central processing portion) and the methods generally used for the basic arithmetic operations of multiplication, division, and signed addition. The paper describes the working of the mechanisms that Babbage devised for storing, transferring, and adding numbers and how they were organized together by the “microprogrammed” control system; the paper also introduces the facilities provided for user- level programming. The intention of the paper is to show that an automatic computing machine could be built using mechanical devices, and that Babbage’s designs provide both an effective set of basic mechanisms and a workable organization of a complete machine.

  • Analytical Engine: the Orig- Inal Computer
    Chapter 2 Analytical Engine: The Orig- inal Computer As we learned in the fourth grade science course, back in 1801, a French man, Joseph Marie Jacquard, invented a power loom that could weave textiles, which had been done for a long time by hand. More interestingly, this machine can weave tex- tiles with patterns such as brocade, damask, and matelasse by controlling the operation with punched wooden cards, held together in a long row by rope. 1 How do these cards work? Each wooden card comes with punched holes, each row of which corresponds to one row of the design. In each position, if the needle needs to go through, there is a hole; other- wise, there is no hole. Multiple rows of holes are punched on each card and all the cards that compose the design of the textile are hooked together in order. 2 What do we get? With the control of such cards, needs go back and forth, moving from left to the right, row by row, and come up with something like the following: Although the punched card concept was based on some even earlier invention by Basile Bou- chon around 1725, “the Jacquard loom was the first machine to use punch cards to con- trol a sequence of operations”. Let’s check out a little demo as how Jacquard’s machine worked. 3 Why do we talk about a loom? With Jacquard loom, if you want to switch to a different pattern, you simply change the punched cards. By the same token, with a modern computer, if you want it to run a different application, you simply load it with a different program, which used to keep on a deck of paper based punched cards.

  • Speculations on Percy Ludgate's Difference Engine
    1 Speculations on Percy Ludgate’s Difference Engine Brian Coghlan Abstract In Percy Ludgate’s 1914 paper for the Napier Tercentenary Exhibition he briefly mentioned that he had designed a simplified difference engine. This paper speculates on how that might have worked. This paper is a work in progress . Index Terms —Percy Ludgate, Analytical Machine, Difference Engine I. INTRODUCTION 1 ERCY Edwin Ludgate (1883-1922) is notable as the second person to publish a design for an Analytical Machine [1][2], P the first after Charles Babbage’s “Analytical Engine” [4]. An analytical machine is equivalent to a general-purpose computer, and in theory can be programmed to solve any solvable problem. It is “Turing complete”, a term invented to reflect Alan Turing’s contribution to the theory of computing. There were only two mechanical designs before the electronic computer era: in 1843 Babbage’s “analytical engine”, then in 1909 Ludgate’s very different “analytical machine”. Babbage only started work on his Analytical Engine in c.1834 when his intensive efforts to design and make a difference engine faltered. This machine was intended to evaluate polynomials using Newton's method of divided differences in order to produce mathematical and nautical tables. In 1914 Ludgate published a paper for the Napier Tercentenary Exhibition [3] (hereafter called “Ludgate 1914”) in which he briefly mentioned that he had designed a simplified difference engine. This paper speculates on how that might have worked. II. DIFFERENCE ENGINES II.1. Babbage’s Difference Engine Charles Babbage is shown in Figure 2(a), drawn late in his life.

  • MACHINES to DO ARITHMETIC EARLY CALCULATORS the Term Computer Dates Back to the 1600S
    ANChp0wTLV5_052002.qxp 5/20/02 10:53 AM Page 5 0.2 Part of the Picture The History of Computing # Four important concepts have shaped the history of computing: I the mechanization of arithmetic; I the stored program; I the graphical user interface; I the computer network. The following timeline of the history of computing shows some of the important events and devices that have implemented these concepts, especially the first two. Additional information about these and the other two important concepts follow the timeline. MACHINES TO DO ARITHMETIC EARLY CALCULATORS The term computer dates back to the 1600s. However, until the 1950s, the term referred almost exclusively to a human who performed computations. For human beings, the task of performing large amounts of computation is one that is laborious, time consuming, and error prone. Thus, the human desire to mechanize arithmetic is an ancient one. One of the earliest “personal calculators” was the abacus,with movable beads strung on rods to count and to do calculations. Although its exact origin is unknown, 3000 B.C. ABACUS the abacus was used by the Chinese perhaps 3000 to 4000 years ago and is still used today throughout Asia. Early mer- chants used the abacus in trading transactions. The ancient British stone monument Stonehenge,located near Salisbury, England, was built between 1900 and 1600 B.C. and, evidently, was used to predict the changes of the seasons. In the twelfth century, a Persian teacher of mathematics in Baghdad, Muhammad ibn-Musa al-Khowarizm, developed 1900-1600 B.C. STONEHENGE some of the first step-by-step procedures for doing computa- tions.
