...The History of the Computer Mouse The computer mouse is considered an input device. With a click of a button, the mouse sends information to the computer. The computer mouse is an interesting device that offers an alternative way to interact with the computer beside a keyboard. A typical mouse has two buttons. At the top of the device you will find a left and right button which allows for “clicks”. There is a scrolling wheel between the two buttons. Douglas Engelbart's device was not the first pointing device. In fact, it seems that the first product was a trackball. It was invented a lot earlier, in 1953, by Tom Cranston, Fred Longstaff and Kenyon Taylor for the Royal Canadian Navy. As part of the secret military project DATAR. The name “trackball” comes from the fact that the respective device actually used a standard Canadian five-pin bowling ball. Just imagine how “easy” using such a product really was. (Vochin, 2009) Engelbart created the first prototypes of the now-familiar device in 1963 at Stanford Research Institute, but he first displayed his creation to the public in Dec 6, 1968. ( Edwards, 2008) The mouse was much larger than today's mouse, square, and had a small button in the top right corner. It used two wheels to roll back and forth. It was the also the first mouse that could fit into a user's hand. In 1972, Jack Hawley and Bill English, inspired by Engelbart’s work, designed a digital mouse for Xerox PARC. This new mouse didn’t require an analog-to-digital...

...Distribution Model Background and History As technology has advanced in recent years, forms of entertainment have shifted from the activities of the outdoor to the games played indoors. Specifically, the emergence of computer gaming as a spectator sport has influenced many firms to develop products that satisfy the unique need of professional and recreational gamers alike. Much like the development of popular sports, such as basketball or soccer, the growth of eSports has created an industry that produces supplementary products required to enjoy the sport. However, instead of basketball and soccer shoes and clothing, the industry if focused on creating high-tech “gaming gear”. These products include higher function keyboards and mice, glasses to protect from glare, and headsets and microphones for gaming oriented communication. As more and more individuals become consumers of this market, the competition in gaming has increased, and the need for better and more sophisticated “gaming gear” equipment has evolved. Initially, with the introduction of computer gaming systems, the basic mouse and keyboard were essential components of most computer games. One of the first innovations in computer gaming history is the introduction of the Apple II and Commodore 64 in the late 1970’s. These were two basic gaming consoles based on the QWERTY keyboards. Both of these products had higher performance and utility in terms of gaming than the average household computer at the time. The evolution...

...The OS, or operating system, has long been a staple of the computer experience, but what aspect of these complex program sets have most attributed to this success? Having delved into this matter, I have concluded that the two aspects which most define this breakthrough popularity would be the GUI (Graphic User Interface) and the Touchscreen. The GUI Originally, a computer user would have to use a lot of command line instructions to launch programs. The introduction of the Graphic User Interface (GUI) changed that by replacing the command line controls for launching programs with icons on the screen, controlled by the mouse. The first “real” version of GUI was introduced to the masses in November of 1985 in the form of Windows 1.0. So what advantages did it offer? Well, for one thing, it allowed for the running of multiple applications or programs at once, a virtual first in the times of less advanced home computers. Now people could swap in and out of their most used or needed applications without excess command line input or closing out the current program and losing their data. This increased speed and productivity as well as making operating the PC much easier and user friendly for the mostly untrained populace. With this new advent, those who shunned the computer because of the heavy command coding needed to work it now had the option to use the newest technology in a way they could easily grasp. Consumers however, were not the only ones who reaped a benefit from...

...Creation of the Mouse : The New Yorker ANNALS OF BUSINESS CREATION MYTH Xerox PARC, Apple, and the truth about innovation. by Malcolm Gladwell MAY 16, 2011 Print More Share Close Reddit Linked In Email The mouse was conceived by the computer scientist Douglas Engelbart, developed by Xerox PARC, and made marketable by Apple. I n late 1979, a twenty-four-year-old entrepreneur paid a visit to a research center in Silicon Valley called Xerox PARC. He was the co-founder of a small computer startup down the road, in Cupertino. His name was Steve Jobs. Xerox PARC was the innovation arm of the Xerox Corporation. It was, and remains, on Coyote Hill Road, in Palo Alto, nestled in the foothills on the edge of town, in a long, low concrete building, with enormous terraces looking out over the jewels of Silicon Valley. To the northwest was Stanford University’s Hoover Tower. To the north was Hewlett-Packard’s sprawling campus. www.newyorker.com/reporting/2011/05/16/110516fa_fact_gladwell?printable=true¤tPage=all 1/12 10/29/13 Xerox PARC, Apple, and the Creation of the Mouse : The New Yorker All around were scores of the other chip designers, software firms, venture capitalists, and hardware-makers. A visitor to PARC, taking in that view, could easily imagine that it was the computer world’s castle, lording over the valley below—and, at the time, this wasn’t far from the truth. In 1970, Xerox had assembled the world’s greatest computer engineers and...

...Case Analysis: Apple Computer Course number: NETW583 Date: May 10th, 2013 The innovation of apple computer began with Steve Jobs and Steve Wozniak in the garage of the parents of Steve Jobs in Mountain View, California. On 1st April 1976, fool’s day, the first apple computer was formed by Ronald Wayne, Steve Wozniak and Steve Jobs. The following year, 1977 the apple company was incorporated. The first Apple Computer was a failure and was followed by the second one which was successful. Today Apple Company is one of the most revolutionary computer companies in the world that is involved in designing, developing and marketing personal computers, media devices, peripherals, networking solutions, and third-party digital content and applications. (Datamonitor, 2011) The timeline gives us an outlook of Apple’s biggest successes and failures. Some of the Apple’s successes come from the reinvention of Apple computer and Apple’s culture. The first success came from the Apple II in 1977. The Apple II was designed for mass production and broad consumer appeal and that must have contributed to the success of Apple II. In 1984, the introduction of first Macintosh was a success. To appeal to the consumes, Apple created hype around the Macintosh with its infamous "1984" Super Bowl commercial, and announced it...

...The History of Macintosh A man by the name of Jef Raskin came up with the idea of building an affordable and easy-to-use computer. It was the first successful computer with a mouse and a GUI, the first Macintosh board that was developed had a 64KB RAM. Raskin created a team of people to start working on his idea. A man by the Steve Jobs was impressed by the design and took an interest in the project that they were doing. Steve Jobs took over with a man name Steve Wozniak, they went to the same college and was in a computer club, they begin to work on it while they were in college, their work place was in a garage where they would work on the computers. They had trouble getting it out there because of another computer company. They were willing to get their computer name out there to let everyone know about it. The first one the made was called Lisa it didn’t do all that well. That led Jobs to move over to Apple and the next one they came out with was called Macintosh. Its debut was announced by a single broadcast during the 1984 Super Bowl, after that was showed Macintosh became popular than IBM. They created a operating system called DOS and sold it. They wanted to steal from XEROX because they came up with the mouse. Bill Gates went to see Steve Jobs at Apple and he showed him the Macintosh, then that’s when Gates and his team started working with Jobs. They start putting out computers and Macintosh became...

...History of Laptop Computers - History Left - Modern Laptop Today It is a little hard to determine what was the first portable or laptop computer, the first portable computers did not look like the book-sized and folding laptops that we are familiar with today, however, they were both portable and lapable, and lead to the development of notebook style laptops. I have outlined several potential firsts below and how each qualifies, many of the off-site links provide good photos of the computers that will let you see the progression in design. The First Laptop? Maybe Designed in 1979 by a Briton, William Moggridge, for Grid Systems Corporation, the Grid Compass was one fifth the weight of any model equivalent in performance and was used by NASA on the space shuttle program in the early 1980's.

...A computer is a machine that is able to take information (input), do some work on or make changes to the information, to make new information (output). Computers have existed for much of human history. Examples of early computers are the astrolabe and the abacus. Modern computers are very different from early computers. They are now very powerful machines that are able to do billions of calculations every second. Most people have used a personal computer in their home or at work. Computers are useful for many different jobs where automatic tasks are useful. Some examples are controlling traffic lights, vehicle computers, security systems, Washing machines and Digital Televisions. A person (called a user) can control a computer by telling it to do things. Some ways of controlling a computer are with a keyboard, mouse, buttons, touch screen. Some very new computers can also be controlled with voice commands or hand gestures. Computers can be designed to do anything with information. Computers are used to control factories, which in the past were controlled by humans. They are also in homes, where they are used for things such as listening to music, reading the news, and writing. Modern computers are electronic machines. A computer is only useful if it has both hardware and software. Hardware is the physical parts the computer is made of - for example keyboard, mouse, screen, tower, and the circuits inside it. Software is the computer programs (mathematical instructions)...

...devices that we put INTO the computer from the real world to receive data or information. ID can be as human interaction as keyboard and mouse or simply environmental data as sensors. This is the list of possible examples of input devices such as : Camera , Compact Disk, Keyboard , Mouse , Digital Camera, Microphone , Drawing Tablet , Scanner, Disk Drive , Joystick , Touch Screen, Barcode reader , Business Card reader , Magnetic-stripe reader, etc. First of all, an input device is any hardware device that sends data to the computer, without any input devices. In other words the input unit is formed by the input devices attached to the computer. An input unit takes the input and converts it into binary form so that it can be understood by the computer. Camera is used during live conversations. The camera transmits a picture from one computer to another, or can be used to record a short video. Compact Disk (CD) - The CD can be put into another computer, and the information can be opened and added or used on the second computer. There is one possible thing like a CD-R or CD-RW can be used as an output device. Keyboard is a way to input letters or numbers into different programs or web-bourses. A keyboard also has special keys that help operate the computer. For ex. key “Microsoft” that helps us to open “start” section whenever we need. Mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different...
