The Weakest Link

Unlike any other communication technology, Power Line Communications (PLC) is a technology whereby a sender modulates the data to be sent, injects it onto medium, and the receiver demodulates the data to read it. The basic difference is that in PLC no extra wiring is needed. Considering the ubiquity of power lines, it implies that with PLC, virtually all line-powered devices can be controlled or monitored. Generally, PLC uses the same electric cables for the purpose of power delivery and…

Wire Rope Wire Rope Definition and Types Wire rope is machine composed of individual wires that have been twisted to form strands and work together to achieve optimum results for the selected operation. Strands are then twisted, to form a wire rope. The parts of a wire rope illustrated in the figure below. The core is the foundation of the rope design. The main functionality of the core is to support the wire stands and maintain them in their position during the lifecycle of the product…

Alejandro Carriegos 9/1/2015 Network Layer The main purpose of the network layer packet is connecting with the destination; it must be familiar with the topology subnet and choose the appropriate paths through it. When the source and destination are on different networks, the network layer (IP), have to deal with these differences. The services provided by the network layer should be independent of the topology subnet. The transport layer must be protected in the number, type, and topology of…

There are two major components to the MPLS architecture and they are control panel and data panel. The control panel has a complex function and is used to exchange the layer 3 routing information (RIP, OSPF, EIGRP, and IGRP) and labels (Label Distribution Protocol (LDP)). The data plane is used to forward the packets based on the destination address or labels. The routers that are capable of routing and switching in the MPLS domain are called LSR (Label Switch Routers). This routing and…

The comparison of lining and interlining materials are given in Table 13.2 Table 13.2 Comparison of lining and interlining materials Sl. No Lining Interlining 1 It is used inside of garments or garment components. It is used between two layers of fabric. 2 It is attached by sewing. It is attached by sewing or applying heat and pressure. 3 Finishing is not necessary. Sometimes finishing is necessary to improve its properties. E.g. shrink resist finish. Crease resists finish. 4 No coating is used…

Text Data Computers represent information using bits. A bit string is a sequence of zero or more bits. This information is encoded by the sender and will be transmitted. The receiver then decodes the information. Data sent may be corrupted along the way because noise may interfere every time an information is transmitted to any channel. A channel is the physical medium through which information is transmitted. Examples of channels include telephone lines, internet cables, fiber optic lines,…

This specifies the general interface between the network layer (IP etc.) and the Data Link layer (Ethernet, Token Ring etc.) It’s the standard for the upper Data Link layer sublayer, also known as the Logical Link Control layer. It’s responsible for flow and error control. The Data Link layer wants to send some data over the network, 802.2 LLC helps make this possible. b. 802.3 – Ethernet 802.3 is the standard which Ethernet operates by. The original 802.3 standard is 10mbps. Commonly, Ethernet…

Design Analysis A connection is recognized in the optical layer regulates to carry the information among the clients in the network. The optical connection is preserved between a source node, s and destination node, d is known as an light path. The problem in finding a route for a light path with wavelength assigned to the light path is submitted as the routing and wavelength assignment problem (RWA). The problem of RWA is divided into two parts : Routing and Wavelength Assignment. In the…

If I were appointed to serve on a criminal justice task force to improve recruitment in law enforcement, I would begin with scaling the structures of each agency from the bottom to the top. Almost every law enforcement agency has a chain of command and one superior at the top of that chain. According to Introduction To Law Enforcement, females seem to be excluded from law enforcement positions that reflect essential decision making (Doerner, 2016). Therefore, the emphasis would be directed on…
