... the required enhancement in the upcoming era apart from traditional input devices based human computer interaction a revolution is also required in the field of computer working power. Moreover the machines are required to be made intelligent in a way that that maximum of the task is automated and that’s only possible by induction of new state of the art computational logics. In other terms one may conclude that the future doest demand the computer that an engineer or a specialized person could operate. The role of engineering and technical people shall be restricted till development and afterwards it shall be in a form that it be handled by the general public users. So what the way to such development the only way it seems functional is that the computing products shall be built in such a manner that it itself become an advisory to user. The only way this requirement seems to be satisfied is that the computer shall be built to provide interface very close to human nature. [14] Linguistic computing can be a solution that does not require user to be specifically trained or even if required just a general brief one to manage the computational device. Currently we interact with mouse that once appeared to be a milestone in redefining the human computer interaction. By then till present it modified a lot from cord to cordless and with even a smoother touch but still it not of worth to compete the upcoming era. [3] [14] Virtual computing an implementation of linguistic is appearing as a bridge of transformation of manual human task to a fully automated span of artificial intelligence. Microsoft has launched its surface technology products and appeared as the pioneer in redefining the human computer interaction. Yielding a state of the art architecture giving a user friendly interface to the end user may we would satisfy the user requirement but in doing so the required computational operation shall boost enormously. Focusing on the current products it could be accomplished by using electronic based computational logics but can we implement the electronic based computational for the future products. But will the future systems based on linguistic computing will they be of the same nature. Surely even saying such a statement sounds stupid. The future computation shall be encountering massive amount of data that too with required parallel processing, individually computed without even a bit of error accommodation. Will the electronic based computation allowing us to do so certainly not. One way is enhancement of the electronic based computation by multi tasking, multi processing and enhancement of processor power but how could we achieve it. Eventually we will be facing the electrons barrier achieving which no further enhancement will be possible. The crystal clear is to stop dreaming it’s just not an electrons worth to full fill such requirements. Surely electrons cannot be extended as we have forced the electron to its maximum potential. Electron based computing being facilitating our lives to great extent but as a nature of human there is no limit or a restriction to human development pace. [13] [14] As in present we have reached the stage of nano technology now can we go further sure we can but will the electron allow us? It’s certainly not permitted they more we push electrons together the more unreliable our computing becomes. As the electrons tend to react with each other resulting is distortion of data that for sure is unbearable. [14] Figure 6 shows optical communication in an optical computer. Photon the fundamental particle of light appears as an alternate to electron. The flaws rather the short coming of electrons can be addressed in photonic based computing. Figure 7 shows components of an optical computer. Some general comparison of certain features of electronic and photonic based computing is as under:- 1. A single photon can be represents in 16 different and distinct ways based on difference in wave length. Implementing photons we can address a large amount of data corresponding to electronic based computing. If we use a 32 bit system by using electronic computing we can address 2^32 bytes per unit time on contrary by doing the same with photon it could be as much as 16^32 bytes per unit time which it self speak the worth of photon with respect to electron. 2. Photon can move from one point to another without need to apply potential for movement, in a straight line with the speed of light. On other end electron require potential to move from one point to another, that too in circular orbits furthermore with the comparatively sluggish speed of electron. 3. In the domain of computer interconnection pathways commonly refer as busses if we use electrons the max we can get is traditional 64 or 128 KB bandwidth busses. Conversely if we come to photonic interconnections we get 35 billion separate non interacting pathways which for sure can’t be even assumed to be ever being achieved using electronic interconnection. 4. Experimentally it is proved that photons can transmit up to 200 GBs of data per second while it seems a fantasy if we even think of comparing electron as a competitor to photon in data transfer rate. One may say that tough we had pushed the limits of electron it’s just the verge of extinction of electrons from the computation. It’s a matter of fact that it’s the end of electrons but shall our computing based on electrons shall it be a greatest ever milestone achieved. Surely it’s foolish to even think of, the upcoming time will be the artificial intelligence rule the era of machine. And the revolution will be brought by photonic computing that surely could be called the next generation of computing. Future of computing defines the glance of the initial interaction between human and computer and its co relation with the present technological miracles. It is assumed that we are in the technological era where we are enjoying the best technology could offer. But wait are we sure that this is the best technology could offer. Tough we had offered user with a high level of user friendliness but a lot more needs to be done. Surface computing is a step from the traditional computing to the fanatic world of artificial intelligence. At initial steps the electronic based computation appears to be supporting but the future high speed computation speed and huge memory requirements appear to be beyond the scope of electronic based computing architecture for which photonic computing is an proposed ...
