...------------------------------------------------- Who is the father of the computer? There are hundreds of people who have major contributions to the field of computing. The following sections detail the primary founding fathers of computing, the computer, and the personal computer we all know and use today. Father of computing Charles Babbage was considered to be the father of computing after his invention and concept of the Analytical Engine in 1837. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory; hailed as the first general-purpose computer concept. Unfortunately, because of funding issues this computer was never built while Charles Babbage was alive. However, in 1910 Henry Babbage, Charles Babbage's youngest son was able to complete a portion of the machine that could perform basic calculations. In 1991, the London Science Museum completed a working version of the Analytical Engine No 2. This version incorporated Babbage's refinements developed during the creation of the Analytical Engine. Although Babbage never completed his invention in his lifetime, his radical ideas and concepts of the computer are what make him the father of computing. Father of the computer There are several people who could be considered as the father of the computer including Alan Turing, John Atanasoff, and John von Neumann. However, for the purpose of this document we're going to be considering Konrad Zuse as the father of the computer with his development of the Z1, Z2...

...History of Computers Computer history can be traced back since the 1880s from the advent typewriting and mechanical counting prototype and also companies such as the National Cash Register which made the atm machines we use today to withdraw cash. John Vincent Atanasoff was a physicist who invented the electronic digital computer. The first electronic digital computer was an idea whose time had come; several groups working more or less independently arrived at almost the same place at the same time. Atanasoff was simply a bit ahead of the pack and for him being ahead had a cost. Atanasoff was required to work alone in a place far removed from the mainstream of computer development. He had trouble finding anyone who recognized the significance of his work. Iowa State supported Atanasoff's work, but none of the university officials fully appreciated what he was up to. Computers have been around since World War II used by the military against the enemy. The Germans used the enigma code machine during the war to secretly send code messages. The enigma code machine was one of their secret weapons they used against the allies. The Enigma offered 150 quintillion possible combinations. Computers have changed since then and now have better versions. Then came the Xerox Parc Alto personal computer developed in 1973, which was a breakthrough then with its built-in mouse and the use of windows. The CHM described it as the Macintosh 10 years before it hit the market. In 1976 apple co-founder...

So a laptop would be best for them because it be easier to take with them on there travels. Having to use a laptop and the number of patients a doctor has and the specific information on that patient requires them to have a larger hard drive size and a more RAM and a faster processor so this laptop would be most useful to a person in this field. A Lawyer would who works in a law firm would spend long hours in a office preparing for a case, so the computer most useful to them would be the Asus - Essentio Desktop. Lawyers can have many clients and work more then one case at a time so they would need to store all the specifics on their case and the information on the person involved in the case they are working on so I feel this desktop would be best for their office because ot has a large hard drive capacity and a good memory capacity. A Physically Scientist would use Acer - Aspire 11.6" Laptop and I feel this laptop would be good for them because in this specific field of science they do more time planning and conducting experiments to investigate and analyze scientific phenomena, writing up results in reports and/or scientific papers or books; maintaining accurate records of results, so...

...Trident University International ITM 433 Module 1 Case ITM 433 – Computer-Human Interaction Module 1: Why do we care about human-computer interaction? Case Assignment: Discuss the application of speech recognition as a tool for Human Computer Interaction Definitions Before getting too far into detail, here are some definitions this paper is based on. Human-Computer Interaction (HCI) is summarily, and loosly, defined as the interaction between people (users) and computers and can be referred to in several different manners. For instance; Computer-Human Interaction (CHI) or Human-Machine Interaction (HMI) are both virtually interchangeable with HCI. The phrase “speech recognition” is rarely, if ever, used outside the context of computer science. Speech recognition refers to the ability of computer-based software to convert spoken words into written (typed/digital) text. Together – HCI/CHI/HMI, etc., insert your acronym of choice but HCI will be used throughout this paper – HCI and speech recognition represent the present and rising future of end-user functionality. The next big thing will be the ability of computers or machines to read your mind instead of verbally instructing it to carry out your bidding… that is sarcasm, of course. However, this current reality of speech recognition software was not stumbled upon and did not happen by chance. A Short History The lever is widely regarded as the first “machine” “invented” and implemented by...

...Jenny Smith November 28, 2011 Dr. Min Young Lee English 121 sec 28 The Coming of Age of the Male Characters in About a Boy About a boy is a contemporary novel written by the British author Nick Hornby. It incorporates constructs of post-modern writing by bringing into focus the artists, and styles, and prose of the vernacular. The setting of the novel takes place in London in the mid 1990s. About a boy gives a unique perspective of a coming of age story. It follows the coming of age of two boys of two very different ages; Will Freeman 36 years old and Marcus 12. This novel shows the contrast between consumerism and materialism with real interpersonal connections. Will Freeman made the decision to pursue materialism rather than personal friendships, and to live in self-imposed isolation. Will had the ability to buy “cool” clothes, and sunglasses and sneakers, and so was never at a loss for acquaintances. Marcus, on the other hand, felt isolation due to a lack of materialism. Marcus was an outsider in his school in London since he could not have the best “coolest” clothes, shoes, and haircuts and thus was always the target of bullying. However, as the plot progresses, Marcus and Will undergo transformational experiences together to become more connected to the people around them. The transformational experiences of Fiona’s suicide, falling in love, and Marcus’ arrest all culminate in the maturation of Will and Marcus’ and the genesis of interpersonal connections between...

Review: The movie is mainly about 36 year old Will Freeman and 12 year old Marcus Brewer. Will is a so called island which means that he wants nothing to do with family related things; all he really wants is relationships without any form of commitment, he therefore goes to a club for single parents called S.P.A.T. There he meets a woman that he likes, but to be with her he makes up that he has a two-year old son named Ted. When he revels that it was a lie to get close to her, she immediately breaks up with him. Will's keeps on courting and the woman (Suzie) takes him to one of the group's picnics where he meets Marcus the son of Suzie's friend, Fiona. At the picnic, Marcus accidentally kills a duck with piece of bread while he is trying to feed it. When a park ranger asks him about it, Will defends Marcus by saying that the bird was already dead. Afterward, when Will and Suzie take Marcus home, they find Fiona, his mother, in the living room, on a pill-overdose trying to commit suicide. Marcus gets uncomfortable with being at home with his mother; therefore he tries to get Will to date her. After only one date this plan fails so Marcus starts following Will around and discovers that Will...

...of my patients. Streams of people are constantly flooding into our hospital, their legs and necks covered in swollen bumps that blacken within hours; goose bumps rise upon their skin as they shiver with exceedingly high fevers, and many are violently throwing up blood. Nurses are madly dashing around from person to person, trying to aid them as much as possible, while our top doctors are desperately racing against time to find some sort of remedy; the hospital is in mass chaos I tell you, mass chaos! I just can’t take it anymore, seeing so many faces that were once smiling and laughing all of twenty-four hours ago to now being masked with such desolate fear and misery. I want to leave this place, just like Dr. Kamish and Dr. Maveroh and about ten more of our staff members that deserted our hospital did. It would be better than hiding in this old closet that I’m in now, which reeks of must and unused cleaning supplies. Although, the stench of dirt and Windex couldn’t possibly smell as bad as the vile odor of the sick and decaying people outside; I don’t want to go out there. I’m petrified. If I go back out there, I could get sick myself, and leave behind my husband and kids. But I can’t stay in here. It’s wrong. I’m going to go out there right now and try to do my best to help the people that have fallen ill during this grave time, the grimmest time of my life. -Sue * * * Dear Journal March 20, 1348 Yesterday at work was one of the most horrifying sights...

...PSYCHOLOGY OF CONFLICTS * What is conflict? * This is a state of opposition, disagreement or incompatibility between two or more people or groups of people, which is sometimes characterized by physical violence. * It is also an inevitable part of our life. * TYPES OF CONFLICT A. Approach-approach conflicts * Occur under two conditions: people attracted about equally to goals. But, carrying out one goal means abandoning the other. Example: You have to choose between buying a car or travelling to Europe. On the same night you want to attend a party and a movie. * Research suggest that approach-approach conflict are easier to resolve than any other type. B. Avoidance-avoidance conflict * When a person is simultaneously repelled by two goals and obliged to select one. * This conflict arouse a great deal of anxiety typically, and they are difficult to resolve. Example: you must choose to clean your room or do the dishes. * Research shows that as organism approach an unattractive choice, it becomes more repellent. C. Single approach-approach conflict * When a person is attracted to and repelled by one goal. Example: An otherwise appealing career may require a lot of education. A luxurious car is costly. Should I have the dentist take care of my cavity? * These conflicts also are difficult to resolve and generates much anxiety. D.

...is Home? In Joan Didion’s essay “On Going Home” she writes about leading a double life. She feels like one person when she’s with her husband and daughter in Los Angeles, and a completely different person when back “home” surrounded by her childhood family in the Central Valley of California. During this particular trip, she begins to reflect on her life in Los Angeles. Didion contemplates the fact that she often feels uneasy around her husband, just like he feels uneasy being around her family. At a crossroad, she must decide not only who she is, and the life she wants, but also the kind of life she wants for her daughter. Her life in Los Angeles has cleansed her from her youth—one that was dusty and full of useless trinkets. She ponders the time her husband wrote the word “D-U-S-T” on those useless trinkets and she remembers her feelings of sadness and indignation. She says, “We live in dusty houses…filled with mementos quite without value to him” (139-40). The dust-covered trinkets signify what is important to her, or what needs to be addressed in her marriage. Yet, these objects just lay there waiting for someone to see them—for someone to dust them off and care for them—not unlike how Didion wishes her husband would see her and nurture her in their marriage. Didion wonders which of her two homes is normal or if they are both flawed. When she and her husband are with her family, he becomes apprehensive about her behavior, “…because once there I fall into their ways, which...
