A GUI (pronounced GOO-ee) is a graphical user interface to a computer. Most of you are using one right now. Take a look at your computer screen, the GUI provides you with windows, pull-down menus, clickable buttons, scroll bars, icons, images and the mouse or pointer. The first user interfaces to computers were not graphical or visually oriented; they were all text and keyboard commands. MS-DOS is an example of a text and keyboard method of computer control that you can still find on many PCs today.

The very first graphical user interface was developed by the Xerox Corporation at their Palo Alto Research Center (PARC) in the 1970s, but it was not until the 1980s when GUIs became widespread and popular. By that time the CPU power and monitors necessary for an effective GUI became cheap enough to use in home computers.

Hello, I am Macintosh

August 6th, 2009 |

hello-i-am-macintosh1In December, 1983, Apple Computers ran its’ famous “1984″ Macintosh television commercial, on a small unknown station solely to make the commercial eligible for awards during 1984. The commercial cost 1.5 million and only ran once in 1983, but news and talk shows everywhere replayed it, making TV history. The next month, Apple Computer ran the same ad during the NFL Super Bowl, and millions of viewers saw their first glimpse of the Macintosh computer. The commercial was directed by Ridley Scott, and the Orwellian scene depicted the IBM world being destroyed by a new machine, the “Macintosh”.

Could we expect anything less from a company that was now being run by the former president of Pepsi-Cola. Steve Jobs, co-founder of Apple Computers had been trying to hire Pepsi’s John Sculley since early 1983. In April of that year he succeeded. But Steve and John discovered that they did not get along and one of John Sculley’s first actions as CEO of Apple was to boot Steve Jobs off the Apple “Lisa” project, the “Lisa” was the first consumer computer with a graphical user interface or GUI. Jobs then switched over to managing the Apple “Macintosh” project begun by Jeff Raskin. Jobs was determined that the new “Macintosh” was going to have a graphical user interface, like the “Lisa” but at a considerably lower cost.

A Different Generations of Computing Devices. What will be the future?

August 4th, 2009 |

a-different-generations-of-computing-devices2The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the development of a product. This term is also used in the different advancements of computer technology. With each new generation, the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization, speed, power, and memory of computers has proportionally increased. New discoveries are constantly being developed that affect the way we live, work and play.

Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices. Read about each generation and the developments that led to the current devices that we use today.

A History of developement of Computers and Networks

July 29th, 2009 |

early-internetWebster’s Dictionary defines “computer” as any programmable electronic device that can store, retrieve, and process data. The basic idea of computing develops in the 1200’s when a Moslem cleric proposes solving problems with a series of written procedures.

As early as the 1640’s mechanical calculators are manufactured for sale. Records exist of earlier machines, but Blaise Pascal invents the first commercial calculator, a hand powered adding machine. Although attempts to multiply mechanically were made by Gottfried Liebnitz in the 1670s the first true multiplying calculator appears in Germany shortly before the American Revolution.
