Throughout our lives, many of us have struggled to remember events in our lives, the names of people we know, and even their faces. Everyone seems to believe that they have the best memory, when in fact, our memories fail us more than we’d care to admit. But over time, with more and more knowledge about what memory is and how it works, psychologists have discovered how we can improve it. But to understand how to improve our memory, we must first learn how it all works. In Laura King’s The…

Question 3: a) What is the main use of stepper motors? In essence, stepper motors are applied in motion-control positioning system. For instance in 3D printers, disk drives, intelligent lighting, scanners, CNC machines, printers, camera lenses, plotters and slot machines. b) What are the similarities and differences between a reluctance, a permanent magnet and hybrid stepper motors? The three motors are similar in that, they all have power electronic control that comes with electronic…

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…

operation within the businesses. the case is given an example which is Amazon by using cloud computing at the marketplace. Amazon use the Web services division (AWS) to get data storage and computing power flexibility. This application supports Amazon to get a large amount of computing resources. Based on client provided data, the AWS can allocate, separate and arrange resources., Cloud computing bring a lot of opportuneness for Amazon, making them save costs and increase profits. Moreover,…

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…

and topology of this connection subnet addresses are available on the transport layer and should be of a single numbering plan (also LAN and WAN) for data transfer. Four specific jobs performed by the Network layer: 1- Communication with the Transport layer Transport layer ensures reliable arrival of messages and offers error mechanisms and data flow control activities. The transport layer provides services for sending "free space", "connection-oriented" and emissions. For connection,…

First appeared in early 1970’systems, There are two kinds of sockets: 1, the connection oriented socket based on TCP 2, connectionless sockets based on user Datagram Protocol (UDP). *The TCP type sockets guarantee data arrives in the correct order, but the user Datagram protocol (UDP) does not. One of the main differences between (” socket” and “server socket “) is; * Socket implemented at the client side to send request to the port of the machine where the server…

Ngobeh Prof. Saunders Review Question Lab September 23, 2015 1. Move copies data from one memory location or register to another. The term “move” is a misnomer because data values in the source location aren’t removed. They’re tested, and copies of these values are placed in the destination location. Therefore, a move operator is really a copy operator. 2. Access to data stored in registers is immediate, but access to data stored in memory locations is slower. Most programs require a temporary…

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…

An entity relationship diagram is a graphical representation of conceptual data organized into a specific and well-defined model.. The objective of an entity relationship diagram is to construct a simple, easy to comprehend, and accessible presented data model consisting of entities, attributes, relationships and cardinalities. The model serves as an instrumental tool for database design, where the model can facilitate communication between the system analyst and the end-user during the…
