To achieve this the ORB must be able must be able to identify and locate objects, handle connections from invoker and the data returned from methods. Communication between the ORB and applications are achieved through IDL stubs and skeletons whilst the OMG has specified IIOP as the protocol through which ORBs may communicate with each other.

  • open graphics library — (graphics, library)   (OpenGL) A multi-platform software interface to graphics hardware, supporting rendering and imaging operations. The OpenGL interface was developed by Silicon Graphics, who license it to other vendors. The OpenGL graphics interface consists of several hundred functions operating on 2D and 3D objects, supporting basic techniques, such as modelling and smooth shading, and advanced techniques, such as texture mapping and motion blur. Many operations require a frame buffer. OpenGL is network-transparent, and a common extension to the X Window System allows an OpenGL client to communicate across a network with a different vendor's OpenGL server. OpenGL is based on Silicon Graphics' proprietary IRIS GL.
  • operational semantics — (theory)   A set of rules specifying how the state of an actual or hypothetical computer changes while executing a program. The overall state is typically divided into a number of components, e.g. stack, heap, registers etc. Each rule specifies certain preconditions on the contents of some components and their new contents after the application of the rule. It is similar in spirit to the notion of a Turing machine, in which actions are precisely described in a mathematical way. Compuare axiomatic semantics, denotational semantics.

  • packed encoding rules — (protocol, standard)   (PER) ASN.1 encoding rules for producing a compact transfer syntax for data structures described in ASN.1, defined in 1994. PER provides a much more compact encoding then BER. It tries to represents the data units using the minimum number of bits. The compactness requires that the decoder knows the complete abstract syntax of the data structure to be decoded, however. Documents: ITU-T X.691, ISO 8825-2.
