Abstract: A method and device for executing data access and storage using a host device, the method comprising providing a removable device for the host operable to effect communication between the host and a remote storage service, wherein the removable device is operable to cache data received from and sent to the storage service, the removable device further operable to effect communication between the host device and the storage service using a wireless communication module.

Abstract: A computer processor and associated computer memory which has in the memory a number of existing content processing operations (CPOs) which include associated description of the type of content they can process, and which has installed, and runable on it, a content processing operation protocol software which is capable of identifying the input requirements of input pins of the CPOs, and which can enable the characteristics of outputs of the CPOs to be identified; and which processor also has installed and runable on it CPO binding software which is adapted to reserve the operation of one CPO and provide its output to another CPO, and which has the protocol necessary to promise the services of one CPO to another CPO, the CPO binding software being able to interpret and use the characteristics of the CPOs expressed in the CPO protocol to determine that it is appropriate to link the one CPO with the other CPO to produce a desired overall function.
