REACTION PAPER

The topic of the video which is about the history of computer was kind of interesting since it high lightened our mind about where the computer had really came from. Not only have that, it also made us understand how the computers of today became very wonderful and powerful.
Before, computers only existed in the imagination of humans and were believed that creating such monstrous device was impossible. It was a huge leap in the field of computer during the 19th century when Charles Babbage developed the 1st modern computer called the difference machine. The most advantageous feature of this machine is that it reflected Babbage’s attitude of being a perfectionist. Although his work was not finished, the detailed text that was written by Ada was significant in modifying his versions and for documentary purposes of his work.
The rapid increase of the American population, on the other hand, triggered the development of a machine that will help the census tabulate such population very fast. Hermin Horrith’s occupation was very helpful to the development of this machine since he used business to gain money to revise his machine which had later evolved into the international business machine.
Although war causes devastation to the environment as well as the people involved, it also had contributed to the development of computers, which is the birth of ENIAC, the first large-scale, general purpose, digital computer that is used to calculate the paths of artillery shells. It was a good and helpful machine during the war since it is able to compute and decode codes very quickly. However, the machine is not practical since you have to always change and monitor its vacuum because it overheats very quickly. Not only that, the machine is very large and contains many wires...

History of Computer Science

...vA Very Brief History of Computer Science Written by Jeffrey Shallit for CS 134 at the University of Waterloo in the summer of 1995. This little web page was hastily stitched together in a few days. Perhaps eventually I will get around to doing a really good job. Suggestions are always welcome. A translation of this web page into French has been prepared by Anne Dicky at the University of Bordeaux. Before 1900 People have been using mechanical devices to aid calculation for thousands of years. For example, the abacus probably existed in Babylonia (present-day Iraq) about 3000 B.C.E. The ancient Greeks developed some very sophisticated analog computers. In 1901, an ancient Greek shipwreck was discovered off the island of Antikythera. Inside was a salt-encrusted device (now called the Antikythera mechanism) that consisted of rusted metal gears and pointers. When this c. 80 B.C.E. device was reconstructed, it produced a mechanism for predicting the motions of the stars and planets. (More Antikythera info here.) John Napier (1550-1617), the Scottish inventor of logarithms, invented Napier's rods (sometimes called "Napier's bones") c. 1610 to simplify the task of multiplication. In 1641 the French mathematician and philosopher Blaise Pascal (1623-1662) built a mechanical adding machine. Similar work was done by Gottfried Wilhelm Leibniz (1646-1716). Leibniz also advocated use of the binary system for doing calculations. Recently it was discovered that Wilhelm Schickard......

Computer Science History

...Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information, whether such information is encoded as bits in a computer memory or transcribed in genes and protein structures in a biological cell.[1] A computer scientist specializes in the theory of computation and the design of computational systems.[2] Its subfields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of Computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on the challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human-computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans. The earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for...

Foundation and History of Computer Science

...INTRODUCTION Computers and computation have been around for a long time and were developed over many years with immense contributions from inventors, engineers, physicists, philosophers, mathematicians, technicians, scholars, and visionaries. Right from ancient times, when man used his fingers to count and keep record and straight to the era of ancient civilisations, computation had been paramount in almost everyday life. The Babylonians used base 60 to calculate and tell hours of the day a format which is still used up to this day, the ancient Egyptians needed math for practical problems: measuring time, flooding of the Nile, cooking and baking, book keeping and accounting, taxes. They also made the first math textbook, which contained the first trigonometry including sine, cosine, tangent, and cotangent (sin = o/h, cos = a/h. tan = o/a, cot = a/o), which has been one of the basis of mathematical calculations till date. The Greeks brought the Pythagorean theory; the Romans brought the Roman Numerals and even the Islam brought the “al jabr” which is known today as “Algebra”. The Chinese brought the remainder theorem and the Indians developed the decimal system, zero and negative numbers, and did early trigonometric work on the sine and cosine. The first computers were calculating machines and over time evolved into the digital computers, as we know them today. It has taken over 180 years for the computer to develop from an idea in Charles Babbage head into an actual......

Role of Information Technology

...The History of Information Technology March 2010 Draft version to appear in the Annual Review of Information Science and Technology, Vol. 45, 2011 Thomas Haigh thaigh@computer.org University of Wisconsin, Milwaukee Thomas Haigh The History of Information Technology – ARIST Draft 2 In many scholarly fields the new entrant must work carefully to discover a gap in the existing literature. When writing a doctoral dissertation on the novels of Nabokov or the plays of Sophocles, clearing intellectual space for new construction can be as difficult as finding space to erect a new building in central London. A search ensues for an untapped archive, an unrecognized nuance, or a theoretical framework able to demolish a sufficiently large body of existing work. The history of information technology is not such a field. From the viewpoint of historians it is more like Chicago in the mid-nineteenth century (Cronon, 1991). Building space is plentiful. Natural resources are plentiful. Capital, infrastructure, and manpower are not. Boosters argue for its “natural advantages” and promise that one day a mighty settlement will rise there. Speculative development is proceeding rapidly and unevenly. But right now the settlers seem a little eccentric and the humble structures they have erected lack the scale and elegance of those in better developed regions. Development is uneven and streets fail to connect. The native inhabitants have their ideas about how things should be done, which......

The Development of Computers

...incredible to consider that in 1969 men landed on the moon using a computer with a 32-kilobyte memory, that was only programmable by the use of punch cards. In 1973, Astronaut Alan Shepherd participated in the first computer "hack" while orbiting the moon in his landing vehicle, as two programmers back on Earth attempted to "hack" into the duplicate computer, to find a way for Shepherd to convince his computer that a catastrophe requiring a mission abort was not happening; the successful hack took 45 minutes to accomplish, and Shepherd went on to hit his golf ball on the moon. Today, the average computer sitting on the desk of a suburban home office has more computing power than the entire U.S. space program that put humans on another world (Rheingold, 2000, p. 4). Computer science has affected the human condition in many radical ways. Throughout its history, its developers have striven to make calculation and computation easier, as well as to offer new means by which the other sciences can be advanced. Modern massively-paralleled super computers help scientists with previously unfeasible problems such as fluid dynamics, complex function convergence, finite element analysis and real time weather dynamics. Likewise, our daily lives are increasingly affected by computers, not only alleviating us from menial tasks but making it possible for us to accomplish more (Rheingold, 2000, p. 7). The personal computer (PC) has revolutionized business and personal activities and......

Niels Ole Fiennemann in the year 2001 came up with Media’s general history. He said that no Society could exist where exchange and production of information is of little significance. Therefore one cannot compare information societies and industrial societies in any steady way. Information societies could be industrial societies and industrial societies could as well mean information societies. The following is a media matrix he suggested. literature cultures: writing(number systems and primary alphabets),secondly print cultures: print + speech + written texts, Second order alphabetical cultures: written texts + speech + analogue electrical media + digital media and speech based oral cultures .This paper seeks to visit the origin of the Information Technology and the developments it has undergone to become what it is today. In history of development of information technology, the paper looks into challenges that were encountered during the advancement stages. Discussion In today’s era, the crucial influence with regard to the concept of information is borrowed from information theory that was developed by Shannon alongside others.......

...Computer science From Wikipedia, the free encyclopedia Jump to: navigation, search Computer science or computing science (abbreviated CS) is the study of the theoretical foundations of information and computation and of practical techniques for their implementation and application in computer systems.[1][2] Computer scientists invent algorithmic processes that create, describe, and transform information and formulate suitable abstractions to model complex systems. Computer science has many sub-fields; some, such as computational complexity theory, study the fundamental properties of computational problems, while others, such as computer graphics, emphasize the computation of specific results. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describe computations, while computer programming applies specific programming languages to solve specific computational problems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans. The general public sometimes confuses computer science with careers that deal with computers (such as information technology), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to......

Job Market

...Beyond supply and demand: Assessing the Ph.D. job market by Elka Jones G reg O’Malley got a taste of the job market for Ph.D. graduates when he supervised several of them after earning his bachelor’s degree. “It was incredible to me that they had gone through so many years of rigorous training,” says O’Malley of his subordinates at his postbaccalaureate publishing job, “only to be working under someone who’d barely finished his undergrad work.” Still, the experience failed to deter him from pursuing a graduate degree of his own: O’Malley currently is enrolled in his second year of the history Ph.D. program at Johns Hopkins University. 22 22 Occupational Outlook Quarterly ● For O’Malley and thousands of others, the desire for a doctorate outweighs concern about the job market that awaits after graduation. Most Ph.D. candidates are willing to dedicate themselves to intensive research and study because they enjoy the subject matter. Winter 2002-03 Statistics also show other, more tangible payoffs for Ph.D. recipients when they enter the labor force. Unemployment rates are consistently lower and earnings are significantly higher for people with a Ph.D. degree than they are for people with lower levels of educational attainment. As chart 1 shows, doctoral degree holders in 2001 had an unemployment rate of slightly more than 1 percent and median annual earnings of $66,000—considerably Elka Jones is an economist in the Office of ...

Introduction to Science

...Science Impacting Modern Life Colorado Technical University November 25, 2013 Abstract As I grow to understand on life in this world I realize that computers are a big part in the way we live our life everyday such as our workforce and for our personal use. For most homes now carries a computer or some type of tablet, a smartphone or some types of handheld electronics products and over the past decades, I have experiences that computers and other devices are better equipped in storing information faster than ever. For the past few years’ we have learned that over the past decade computer had improved and designs in more ways since 10 years ago. I have learned and have discussed how the electron spin of atoms hints at a new approach in the computer revolution for the near future. In this paper I will discuss new ways in development in material science which allowed many changes in the life of computers and the essential properties of the life in which has influenced the industrial of computers. Science Impacting Modern Life The three essential properties of every material are 1: the kind of atoms of which it is made, 2: the way those atoms are arranged, and 3: the way the atoms are bonded to each other” and (Trefil and Hazen), stated that “Based on our understanding of atoms and their chemical bonding, we now realize that the properties of every material depend on three essential features, such as As we learned we will realize that all materials have......

Gendered Subjects

...is it that women make up such a small percentage compared to men in this field? Is it because they are not capable? Or that they do not want to be associated with the “geek” culture of science technology? Women make up more than half of the college population in America,and today women are beginning to major in majors such as math and science in impressive numbers, but with computer science and technology it is a whole different story. On top of the small numbers of women entering the field, the typicality of a women to enter the field only to leave it after a few short years is extremely common. The number of women in computer science and technology who enter and remain in these fields is very low because of underlining cultural stereotypes and the higher demand on women to be in the home juggling with multiple responsibilities. Men compromise a whopping eighty to eighty-five percent of people who enroll in computer science related fields in the university level. Carnegie Mellon University in particular has a ten to one ratio of men compared to women in the field. In 2004-2005, the number of women pursuing Bachelor's degrees in Computer Science was a mere twenty percent (Fry, 2001). Ellen Spurtus, one of the few women in the technology field, remembers as a girl when she attended a computer camp with boy to girl ratio of six to one (Stross, 2008). After having a small look at some of the figures dealing with women in this industry, it is not hard to see that the......
