Grid Computing Some consider this to be the “the third information technology wave” after the Internet and Web, and will be the backbone of the next generation of services and applications that are going to further the research and development of GIS and related areas. Grid computing allows for the sharing of processing power, enabling the attainment of high performances in computing, management and services. Grid computing, (unlike the conventional supercomputer that does parallel computing by linking multiple processors over a system bus) uses a network of computers to execute a program. The problem of using multiple computers lies in the difficulty of dividing up the tasks among the computers, without having to reference portions of the code being executed on other CPUs. Parallel processing Parallel processing is the use of multiple CPU’s to execute different sections of a program together. Remote sensing and surveying equipment have been providing vast amounts of spatial information, and how to manage, process or dispose of this data have become major issues in the field of Geographic Information Science (GIS). To solve these problems there has been much research into the area of parallel .. more»

Optical computing means performing computations, operations, storage and transmission of data using light instead of electricity.  Instead of silicon chips optical computer uses organic polymers like phthalocyanine and polydiacetylene.Optical technology promises massive upgrades in the efficiency and speed of computers, as well as significant shrinkage in their size and cost. An optical desktop computer is capable of processing data up to 1, 00,000 times faster than current models. Advantages Optical computing is cheaper or more powerful than conventional computers. Within one data path several data sets can be transmitted parallel at the same time using different wavelengths or polarizations. Data paths are able to cross each other without interference. The superior velocity of light allows extreme processing speeds. Optical computers are said to run much faster than electronic computers Disadvantages   The development of its price is still expensive Optical components can be build small and compact but not really miniaturized Optical computers may use a different architecture. So these programs cannot use the full optical computers High-tech factory .. more»
