Even the processor and internal storage are regarded as two major standards of identification of a computer; the only thing that we can see and communicate with directly is the interface, or the GUI, which mentioned by the passage. Just like we can only talk with language, the interface of a computer is the only way that could make it readable and understandable to users. First concept of what we consider a modern computer is the Turing machine. It was first proposed by Alan Turing in 1936, a device that printed symbols on paper tape in a manner that emulated a person following a series of logical instructions. And during the 30 years after the Turing machine came to world, the computers were only able to use by scientists and military. The difficulty of readability is one of the reasons. People cannot work on the computers visible, the engineering instructions are too complicated for the ordinary users. Thereafter the radical revolution came, the first implementation of a GUI, Engelbart’s (NLS) brought a virtual desktop incorporating windows, menus, icons, and folders. Then the computer with an interfacing monitor became the symbol of the modern century. It was also the inanition, which inspired Steve Jobs and Bill Gates building the Apple and Microsoft’s empires. To adopt with the computer revolution, the Internet changed with the same idea., The predecessor of Internet, ARPANET, originated by DARPA (Defense Advanced Research Projects Agency) in 1969. According to the name of APARNET’s inventing organization, it is easy to understand its military defensive use. Even the new technology allowed Professor Leonard Kleinrock to send a revolutionary message from his laboratory, the difficulties of handling still limited the Internet technology to be used by wider audience. But this time, people spent less time finding it a solution. Mosaic’s browser made a possibility for everyone to use the Internet. The point-and-click browser gave people a visible interface and became a testament of the future browsers. People could record websites and browse the webpages with the guide of the title bar, no more instructions or codes were needed. Then the Internet grew so fast, the GUI brought a new era to the world. People always call the computer and Internet as the Creator of modern society; after reading this passage, it’s safe to call the GUI as the Creator’s spirit.
