Cabling – Definitions
1. Application- A program running on a computer.
2. Unshielded Twisted-Pair- A pair of copper wires twisted together with no shielding.
3. Fiber-Optic Cable- Cable with one or more glass fibers that uses light to transfer data.
4. Dark Fiber- A fiber that is not carrying light. Used when extra fiber capacity is installed.

7. Riser- A space for indoor cables that allow cables to pass between floors, normally a vertical shaft or space.
8. Rip Cord- String built into fiber-optic cable that is used to split the outer jacket of the cable
9. Core- The central part of a fiber optic cable that the light transmitted on.
10. Attenuation- A term that indicates a decrease in power from one point to another.
11. Noise- A signal that interferes with the desired signal passing thru the cable.
12. Headroom- The number of db that a system exceeds the minimum defined requirements.
13. ANSI- The primary organization for developing technology standards in the U.S.
14. NFPA- A U.S organization with international membership, to establish and update fire protection and prevention safeguards.
15. FCC- A government agency that regulates interstate and international communications
16. NIST- A Technology Administration that sets standards as needed by industry or government programs.
17. OSHA- A government agency that makes and enforces rules to provide safe and healthy work environment.
18. Equipment Room- A space set aside for telecommunications equipment that serves the occupants of the building or multiple buildings in a campus environment.
19. Topology- The physical configuration that describes a local communications network, most common topologies is bus, ring and star.

    Ants may lay pheromone trails when travelling from the nest to food, or from food to the nest, or when travelling in either direction depending on the species. They also follow these trails with a allegiance which is a function of the trail strength, among other variables. Ants drop pheromones as they walk by stopping briefly and touching their gaster, which carries the pheromone secreting gland, on the ground. The strength of the trail they lay is a function of the rate at which they make deposits, and the amount per deposit. Since pheromones evaporate and diffuse away, the strength of the trail when it is encountered by another ant is a function of the original strength, and the time since the trail…

    As it is evident from the related work discussed in the section 2, when small files are stored on HDFS, disk utilization is not a bottleneck. In general, small file problem occurs when memory of NameNode is highly consumed by the metadata and BlockMap of huge numbers of files. NameNode stores file system metadata in main memory and the metadata of one file takes about 250 bytes of memory. For each block by default three replicas are created and its metadata takes about 368 bytes [9]. Let the number of memory bytes that NameNode consumed by itself be denoted as α. Let the number of memory bytes that are consumed by the BlockMap be denoted as β. The size of an HDFS block is denoted as S. Further assume that there are N…

    Graph 1, illustrates the pH of each quadrat. The pH in Quadrat 1 was more acidic than the pH in Quadrat 2, 3, and 4 this is due to the slope of the ground (refer to Graph 8), different soil substrate and the decomposition of organic matter. As can be seen from Graph 8, the soil pH increased with a decrease in the slope of the ground. In Quadrat 1, the soil had a pH of 7.5 due to having a higher soil elevation of -8° in comparison to Quadrat 2, 3 and 4, in which the slope of the ground was -2°, -2° and -1°, respectively and the pH was 9 within each quadrat. This makes Quadrat 1 more prone to acidification, as it receives more acid rain than soils in lower elevations. Quadrat 1 is more acidic than Quadrat 2, 3 and 4 because at low tide (Quadrat…

    Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin, these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin.…

    To understand how to interface with the local exchange you must first understand the different networks that comprise it. The first network is the access network. The access network is the network that connects the individual user or business with the telecommunications system. It’s a critical portion of the network because it is the part of the network that reaches the end users and “connects them”. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange.…

    Copper cables carry information as an electrical signal, which may be digital, as in phone lines, or analogue, as in audio speaker cable. In optical fibers, however, data is carried digitally by light from a laser or LED. This travels along the cable by means of Total Internal Reflection, bouncing from one side of the glass's inner surface to another and therefore following the cable's path.…

    Fiber Optics

    • 3 Pages

    Fiber optics uses glass or plastic fibers to transmit data in the form of light sent along long distances. These cables are used in TV’s, telephones, the internet, and in medical imaging. Information is sent as pulses of light that must be repeated at different points. Fiber optic lines can carry much more information at a time than traditional copper wires. The ability of fiber optic lines to carry digital data has significantly contributed to advances in digital communications because glass fibers are less subject to interference. Despite the lower interference, installing these fiber optic cables is difficult and time-consuming, complex, and expensive to install and operate. In order to package fiber into a commercially viable product, it typically is protectively coated by using ultraviolet, light-cured acrylate polymers, then terminated with optical fiber connectors, and finally assembled into a cable. After that, it can be laid in the ground and then run…
