Document Summary
Allows new types of apps like augmented reality. Use ieee 802. 11 wireless, or cellular data networks for connectivity. Collection of separate, possibly heterogeneous, systems networked together. Many systems now servers, responding to requests generated by clients. Compute-server system provides interface to client to request service. File-server system provides interface for clients to store and retrieve files. Broadcast request for service and respond to requests via discovery protocol. Emulation when source cpu type differs from target type. When computer language not compiled to native code-interpretation. Virtualization os natively compiled for cpu, running guest oses also natively compiled. Vmware running on win xp guests, each app hosts. Grub software allows choosing between linux/windows on boot, vm manager allows all. Logical extension of virtualization because it uses virtualization as the base for its functionality. Software as a servis(saas)-one or more apps available via internet. Car engines, manufacturing robots, dvd players, microwave ovens, smart buildings. Fixed time constraints, process sensor inputs, control devices.
