  • GUI History Abridged
    "So we went to Atari and said, 'Hey, we've got this amazing thing, even built with some of your parts, and what do you think about funding us? Or we'll give it to you. We just want to do it. Pay our salary, we'll come work for you.' And they said, 'No.' So then we went to Hewlett-Packard, and they said, 'Hey, we don't need you. You haven't got through college yet.'" -- Apple Computer Inc. founder Steve Jobs on attempts to get Atari and HP interested in his and Steve Wozniak's personal computer “What I saw in the Xerox PARC technology was the caveman interface, you point and you grunt. A massive winding down, regressing away from language, in order to address the technological nervousness of the user.” –- an IBM technician lambasting the Apple Lisa’s GUI "There is no reason anyone would want a computer in their home." -- Ken Olson, President, Chairman and Founder of Digital Equipment Corp., 1977 1 1930’s Vannevar Bush, American engineer. Worked on analog computing and on the Manhattan Project. Wrote of an adjustable microfilm viewer he called the "Memex," looking like a desk with two touch screen graphical displays, a keyboard, and a scanner attached to it. It would allow the user to access all human knowledge using connections very similar to how hyperlinks work. At this point, the digital computer had not been invented, so there was no way for such a device to actually work, and Bush's ideas were not widely read or discussed at that time.

  • A History of the GUI 11/3/11 9:20 PM
    A History of the GUI 11/3/11 9:20 PM A History of the GUI By Jeremy Reimer | Published 6 years ago Introduction Today, almost everybody in the developed world interacts with personal computers in some form or another. We use them at home and at work, for entertainment, information, and as tools to leverage our knowledge and intelligence. It is pretty much assumed whenever anyone sits down to use a personal computer that it will operate with a graphical user interface. We expect to interact with it primarily using a mouse, launch programs by clicking on icons, and manipulate various windows on the screen using graphical controls. But this was not always the case. Why did computers come to adopt the GUI as their primary mode of interaction, and how did the GUI evolve to be the way it is today? In what follows, I?ll be presenting a brief introduction to the history of the GUI. The topic, as you might expect, is broad, and very deep. This article will touch on the high points, while giving an overview of GUI development. Prehistory Like many developments in the history of computing, some of the ideas for a GUI computer were thought of long before the technology was even available to build such a machine. One of the first people to express these ideas was Vannevar Bush. In the early 1930s he first wrote of a device he called the "Memex," which he envisioned as looking like a desk with two touch screen graphical displays, a keyboard, and a scanner attached to it.

Below is a basic list of the different operating systems and its different categories. operating systems and a few examples of operating systems Operating systems are being developed by a large that fall into each of the categories. Many computer number of academic and commercial organizations for operating systems will fall into more than one of the below the last several decades. This paper, therefore, categories.With the integration of computers and concentrates on the different categories of operating telecommunications, the mode of information access systems with special emphasis to those that had deep becomes an important issue.

  • A History of the GUI
    FOUNDATIONS OF COMPUTING P/T TUTORIAL Reading for weeks 6&7 A History of the GUI By Jeremy Reimer | Published: May 05, 2005 - 01:40AM CT http://arstechnica.com/articles/paedia/gui.ars/1 Introduction Today, almost everybody in the developed world interacts with personal computers in some form or another. We use them at home and at work, for entertainment, information, and as tools to leverage our knowledge and intelligence. It is pretty much assumed whenever anyone sits down to use a personal computer that it will operate with a graphical user interface. We expect to interact with it primarily using a mouse, launch programs by clicking on icons, and manipulate various windows on the screen using graphical controls. But this was not always the case. Why did computers come to adopt the GUI as their primary mode of interaction, and how did the GUI evolve to be the way it is today? In what follows, I’ll be presenting a brief introduction to the history of the GUI. The topic, as you might expect, is broad, and very deep. This article will touch on the high points, while giving an overview of GUI development. Prehistory Like many developments in the history of computing, some of the ideas for a GUI computer were thought of long before the technology was even available to build such a machine. One of the first people to express these ideas was Vannevar Bush. In the early 1930s he first wrote of a device he called the "Memex," which he envisioned as looking like a desk with two touch screen graphical displays, a keyboard, and a scanner attached to it.
