TAILIEUCHUNG - Fiber Optics Illustrated Dictionary - Part 92

The Fiber Optics Illustrated Dictionary - Part 92 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 may also be a relay and may selectively collect or relay multiple messages. A relay may alter the formal of a message but it is generally not recommended unless it is unable to discern the proper implementation of the format in which case it should modify it. Messages are transported over User Datagram Protocol UDP using port 514 and are usually received over port 514. See RFC 3164. sysop system operator. The sysop or systems administrator sometimes also called the super user due to his or her higher access privileges and power over other accounts on a system. The system operator is a technical expert with high security privileges managing a bulletin board system or computer network. On small systems like BBSs these tasks may be performed by one person. On medium-sized systems sometimes assisting sysops are assigned intermediary privileges between those of the super user and regular system users. Larger systems often split the installation security administration file management diagnostic and tuning responsibilities of a network among a number of system operators or may even have an entire facility devoted to the administration of the network. system disk A disk that includes boot information that is low-level operating information from which a computer system can be started. This may be a floppy drive hard disk CD-ROM or other disk with system files somewhat transparent to the user. Without certain system files a computer cannot configure itself to recognize peripherals available memory monitor types etc. See bootstrap operating system system integrator A commercial vendor offering a variety of network design and implementation services according to the configuration needs of various customers. system reliability architecture SRA. Systems designed as fault tolerant and reliable and which function even while undergoing maintenance checks and procedures. SRA implies systems which incorporate redundancy the ability to hot swap .
