...------------------------------------------------- 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...

...Steve Jobs I am going to be telling you about a great man of our time. He was a great business man and inventor. He started from nothing and made it big. Steve Jobs is a hero for the whole world to look up to. He started out as an adopted child worked his way up to being a millionaire. When he was younger he liked the idea of building things and he was interested in computers. Over the years he tried many things and finally ended up going to college (Steve Jobs Encyclopedia Britannica). After a short time he dropped out, in my opinion a bad idea but it seemed to work out for him. He ended up sleeping on his friend’s floor and only had money from turning in bottles (all about Steve Jobs.com). Steve Jobs finally found his calling when he was desperate for money. He took a job at Atari. He learned a lot from Nolan Bushnell the founder of Atari (all about Steve Jobs.com). This is where he got his love for working on computers. He started his company with a friend Woz. To start building the computers that Woz had come up with they sold a VW Van and an hp 65 calculator (all about Steve Jobs.com). Steve came up with the name Apple for the company’s name and they had a friend Ron Wayne help them set up the company. Their first customer was Paul Terrel and he bought 50 computers (all about Steve Jobs.com). After that they started building the computers in Steve’s garage. They started selling them by them self and tried to sell to a company homebrew and got turned down...

...to learn about the amazing things you can make computers do along with that I learnt about the various programs that are being offered in the computer related field. The three lectures delivered during this year that really impressed me were computer graphics by Petro Faloutsos, computer vision and robotics by John Tsotsos and computer security by Hamzeh Roumani. The reason for choosing these three topics is because computer graphics has always been one of my main interests and this lecture gave me a chance to know more about simulation and animation. John Tsotsos talked about his research related to computer vision and robotics because of which I developed an interest in robots and last but not a lecture about computer security in which I learnt new stuff about cryptography. Animating virtual humans is a crucial element of interactive applications according to professor Petro Faloutsos. These applications include medicine, critical situation simulation and interactive applications. He also gave us a little information about his ongoing project on human simulation and modeling. He told us that if we want to simulate a virtual human with high fidelity, we would have to have a layered system which consists of motor control, coordinated level behaviors and expressive facial animations and also mentioned about designing hardware and software accelerators for the physics based simulation. The very talented Professor John told us that his research was based on computer vision...

...The Effect of a Computer Simulation Activity versus a Hands-on Activity on Product Creativity in Technology Education Kurt Y. Michael Computer use in the classroom has become a popular method of instruction for many technology educators. This may be due to the fact that software programs have advanced beyond the early days of drill and practice instruction. With the introduction of the graphical user interface, increased processing speed, and affordability, computer use in education has finally come of age. Software designers are now able to design multidimensional educational programs that include high quality graphics, stereo sound, and real time interaction (Bilan, 1992). One area of noticeable improvement is computer simulations. Computer simulations are software programs that either replicate or mimic real world phenomena. If implemented correctly, computer simulations can help students learn about technological events and processes that may otherwise be unattainable due to cost, feasibility, or safety. Studies have shown that computer simulators can: 1. Be equally as effective as real life, hands-on laboratory experiences in teaching students scientific concepts (Choi and Gennaro, 1987). 2. Enhance the learning achievement levels of students (Betz, 1996). 3. Enhance the problem solving skills of students (Gokhale, 1996). 4. Foster peer interaction (Bilan, 1992). The educational benefits of computer simulations for learning are promising. Some researchers even suspect...

...of Mac and Pc. Many people pick a computer based on what they are used for to and don’t find the computer that’s right for them. Others don’t find out the facts about each computer and just go with the cheapest because it’s cheap, even though they would be getting a cheap computer it can still be the wrong kind of computer for them, plus it wouldn’t work to their advantage. Before reading this you have to dismiss the ideas you had about Mac’s and Pc’s. If you put aside what you think you know about Pc, and Mac you will understand what computer is best for you. “Mac is a line of personal (PCs) designed, developed, and marketed by Inc. It was initially targeted mainly at the home, education, and creative professional markets. Since the introduction of the Macintosh, the computer has seen significant evolution now making it one of, if not the most powerful general-purpose computers on the market. It now targets the business, science, and law markets as well.” “Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft. Microsoft introduced an operating named Windows on November 20, 1985 as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUI).[4] Microsoft Windows came to dominate the world’s computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984.” The most important part of both computer systems is the cold hard facts between...

...Introduction to Computer Hardware In general, there is very little that you as a future manager need to know about computer hardware, other than some basic vocabulary. The key ideas we want to you understand about hardware are: * Computers are basically simple electronic devices. While what they do may seem magical, very little of the magic comes from the computer itself. In fact computers are limited in what they can do. * More of the magic comes from the software – the set of instructions that tell the computer how to process and display data (and we’ll talk more about that in the following classes). * Most of the magic comes from the way people use the information produced by the computer, and (most importantly) the way they recognize, manage, and overcome the limits of computer-based information. To understand and manage these limitations, you need to have a basic understanding of hardware and software. We can use the systems model (input-process-output) to categorize hardware. There are input devices (e.g., a keyboard) and output devices (e.g. a monitor). We also need to store intermediate and final results of computations, so we need data storage devices (e.g., hard drives). The process is represented by the “processing unit” of the computer (also called a Central Processing Unit or CPU). While it gets a little technical, it is worth understanding how a CPU works, because you need to understand that before you can understand how software works...

...Computers have brought about a revolution across all industries. They have changed the face of society. They are no longer specialized tools to be used by specially trained people. They are ubiquitous and used in almost every sphere of life. Computers are the best means for storage and management of data, they can serve as huge knowledge bases and can be harnessed for all sorts of financial transactions owing to their processing power and storage capacities. As computers are a daily utility, they have gained immense importance in day-to-day life. Their increasing utility has made computer education the need of the day. By computer education, we mean, gaining the know-how of the basic concepts related to a computer and gaining the basic knowledge of computer operation. Knowing about the basic components of a computer, the basic concepts behind the use of computers and the know-how of some of the elementary computer applications constitutes computer education. Learning about the computer basics followed by a practical experience of using a computer is the key to computer education. As computers are widely used today, acquiring computer education is the need of the day. Computers are not only storage devices and processing units, but also are excellent communication media. They are the means to access the Internet and get connected to the world. They are also an effective audio-visual media. Computers can be used to access a vast knowledge base and search for information archives...

... WEEK 10 8/28/13 Explain computer ethics Computers are special technology and they raise some special ethical issues. In this essay I will discuss what makes computers different from other technology and how this difference makes a difference in ethical considerations. In particular, I want to characterize computer ethics and show why this emerging field is both intellectually interesting and enormously important. On my view, computer ethics is the analysis of the nature and social impact of computer technology and the corresponding formulation and justification of policies for the ethical use of such technology. I use the phrase "computer technology" because I take the subject matter of the field broadly to include computers and associated technology. For instance, I include concerns about software as well as hardware and concerns about networks connecting computers as well as computers themselves. A typical problem in computer ethics arises because there is a policy vacuum about how computer technology should be used. Computers provide us with new capabilities and these in turn give us new choices for action. Often, either no policies for conduct in these situations exist or existing policies seem inadequate. A central task of computer ethics is to determine what we should do in such cases, i.e., to formulate policies to guide our actions. Of course, some ethical situations confront us as individuals and some as a society. Computer ethics includes consideration of...

...Transistors - The computer contains millions of transistors, which are used to create machine language using logic gates that turn on and off the circuits. Machine language - All computers and electronic devices communicate in binary, which is a series of 0's and 1's or Off and On electrical signals. All software written on your computer is created in a high-level programming language that humans can understand, when complete the program is compiled into the machine language that computers understand. ASCII codes - Each binary 0 or 1 is considered a bit and each number, letter, or other character is made up eight bits (one byte). A common method for storing and editing text is done with ASCII codes, which is one byte of binary. For example, the lowercase letter "a" has a ASCII code decimal value of 97, which is 01100001 in binary. Motherboard - The Motherboard is the largest circuit board in the computer that holds and connects everything together. Without the motherboard, components like your processor and memory couldn't communicate with each other. Processor - The processor or CPU is the brain of the computer and is where all instructions given to the computer are handled. Computer memory - Not to be confused with disk storage, the computer memory (RAM,) is volatile memory and is used to store currently running applications. When the computer is turned off, all data in the memory is lost. Computer disk storage - Also considered a memory, but a...

...Weird Al’s song “It’s All About the Pentiums”, the movie “Live Free or Die Hard” and the poem “Praise Song for the Day” by Elizabeth Alexander each have a common theme that relates to the computer industry in which describing the need to continually advance towards the future. The poem “Praise Song for the Day” was written by Elizabeth Alexander in 2009 as a tribute to President Obama’s inauguration. There is a lot of directions this poem can go, as far as whom it relates to. The main point is that people are here to help out each other. This is a song in the music industry provided by the artist Weird Al Yankovic. This song is a remix of the Puff Daddy song “It’s All About the Benjamins. This “nerdcore hip-hop” song was released on the album “Running with Scissors” in 1999.
