TAILIEUCHUNG - Fiber Optics Illustrated Dictionary - Part 35

The Fiber Optics Illustrated Dictionary - Part 35 fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context | Fiber Optics Illustrated Dictionary and input output peripherals are event-driven or event initiators. eventual Byzantine agreement EBA. In EBA a number of coordinated processors with some specified upper value for faulty processors agree on a slate or value among those considered to be reliable. Thus a state of mutual agreement is negotiated among nonfaulty processors in a fault-tolerant system but the processing does not have to be simultaneous. See Byzantine agreement and Byzantine Generals problem for a history and fuller explanation. EVVOS See European Workshop in Open Systems Open Systems Interconnection. E WP electronic white pages.

A prefix for an SI unit quantity of 1018 or 1 000 000 000 000 000 000. It s a gargantuan quantity. See zeta- atto- ExCa Exchangeable Card Architecture. An open socket architecture extension to PCMCIA for use on Intel x86-based computers introduced by Intel in the early 1990s. The software specification provides standardized socket card and client services. ExCA allows interfacing of PCMCIA devices with computers particularly mobile computers which are more likely to have PCMCIA slots. See Personal Computer Memory Card International Association. exception 1. error or unusual occurrence such as an abnormal signal data falling outside a certain specified range or a deviation from normal program execution. Common exception conditions in programming include stack overflow and divide-by-zero errors. In software development exception handlers can be included in the code to detect and manage error conditions and resume program execution. 2. In ATM a connectivity advertisement in a PNNI complex node representation that represents something other than the default setting of the node representation. excess burst size See burst size excess. excess noise current noise Undesirable noise that results .
