Graphical user interface

accessible nor convenient for people. The Apple Macintosh was one of the first computers to truly change the idea of computers only being useful in the workplace and gave people an easier way to access and utilize information. The use of a Graphical User Interface and the push for the Macintosh to be used for educational purposes gave the Macintosh an edge over the competition and pioneered the current technology used today. The Apple Macintosh computer revolutionized the encounters individuals had

Using either GNOME or KDE, you can decide what interface you want and then add only the features that fit your needs quickly and easily. If you are concerned with standardization, do not worry. Linux sticks to the Unix standards. The Institute of Electrical and Electronics Engineers put together the American National Standards Institute for Unix named the Portable Operating System Interface for Computer Environments. It dictates a universal standard on how the Unix-based

mouse debuted computers had just arrived into the small business market. They were still costly and not economically viable for home computer users. Because of the great expense involved there was no need to cater to the needs of the general public, which requires user-friendly computers. User-friendly means that the computer's operating system and interface are easy-to-learn. The change to using the mouse was also uneconomical for computer manufacturers of the time because there was no demand for

a program that enables a computer to perform a specific task. Computer is useless without a software. For example without internet browser you cannot search anything on the internet. You need system software such as word processer, which enables a user to perform a task, and system software such as an operating system, which enables software to run properly. Computer software has to be installed within the computer storage (such as hard drive, memory, or RAM). Once the software is installed, the

kind of computer was introduced the world in the 1940s, the major event which has changed the history of human- computer interaction was the advent of the graphical user interface at Xerox PARC in the 1970s. Along with a pointing device, typically a mouse, users are able to point to parts of the display. With the GUI which makes the interface to the computer primarily a visual medium, the virtual world inside the computer is portrayed graphically on the display. According to Shneiderman’s the future

and convenience their lives. Most users do not even consider the complexity that allows the device to operate. And staggeringly, every electronic item we use today has some sort of functioning operating system to allow it to carry out its objective task. A computer operating system is one such program that has rapidly evolved to simply the use and capabilities of computers. Two widely known and used operating systems, Windows and Linux, are contending for the user market and have transformed over

As a consequence, Gates devised the mouse to its already established interface. Eventually, other companies began to develop similar computers featuring screens and other controls similar to the mouse. However, Gates vision was unique because he wanted his computer to reach the general public while those other companies were

existing disk operating system.Windows finally allowed DOS users to visually navigate a virtual desktop, opening graphical “windows” displaying the contents of electronic folders and files with the click of a mouse button, rather than typing commands and directory paths at a text prompt. Subsequent versions introduced more functionality including Windows File Manager, Program Manager, and print manager along with a much powerful interface. Microsoft developed Windows packages that mainly aimed for

hardware. This relieves application programs from having to manage these details and makes it easier to write applications. Almost all computers use an OS of some type. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. The Operating System will identify at which time the CPU will perform which operation and in which Time

ensuring that unauthorised users do not access the system. There are many types of operating systems, a few are listed below: Windows Linux Mac OS/OSX Windows Windows is one of the biggest operating systems in the world and was created in 1981 by chase bishop. The purpose of windows is to improve on previous systems and make them all better. This operating system is a graphical
