GUI, Ethernet and OOPs

Tweet

GUI or Graphical User Interface is used to provide users with easy to use interface in display systems. It was first widely used in Apple II systems and broke the scene of computing. Ethernet is use for locating individual systems in network using MAC address. It is the most important device used for communicating devices. May be best described as large scale network interconnecting and can describe the reason for Internet explosion beside HTTP protocol and hyperlinks. OOPs or Object Oriented Programming that dominate the web via Java, Php and many other languages have revolunized the programming world. It has solved the problems of most lenghty programs and improved coding process viewing coding as a real life process rather than just theory based procedural programming. What do we have common in all these. All have their roots from Xerox, a photocopier machine maker, whose primary aim was to focus on coping papers never thought about its real life use and lost the trends to others. If they had realized its real use then they would have been the Quadllion dollar industry than any other you see now. But their thinking was left behind by just few members who developed the best and who left the best to others.
