A Just-in-Time Mechanism for Computer System

Abstract

As the installed programs will consume increasing space of hard disk, the computer becomes more and more bulky and costly. However, it’s harder and harder to make a larger yet still light and cheap hard disk. Therefore, computers used in most occasions are suggested to cancel their hard disks, and have their operating system programs and the application programs ‘installed’ on internet, instead of being installed on local hard disk. The data is accessed via supper high speed internet when the program booting. The operating system additionally serves as an open platform for registering the application software as well as the traditional role. This mechanism will bring us many gains. First, the user will no longer be restricted by the limited storage space, and will literarily have a never discarded and unlimited storage space that is shared by his or her all intelligent terminals. Second, the computers can become lighter and therefore easier to carry. Third, the user can get the latest version program once he or she launches the program. Last, the program provider can take the initiative to push the newest message to its users easily if they have subscribed.
