Data modeling

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…

The organization had total three possible solutions for the problems they were facing. The first solution was Google drive which is considered as a good alternative in place for an enterprise program. The second solution is WordPress which has blogs, websites and online publications and also has an easy-to-use content management system which allows from drafting articles to scheduling of posts. The third solution which the organization finally adopted to solve the problems was the SharePoint.…

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…

design and age. Older model equipment built more than 10 years ago will run at 10Mbps, devices built in the last ten years run at least 100Mbps. Generally, the speed determines how much data can be transferred throughout the network. The network devices are connected together via network switches that forward packets of data to the correct destinations. Switches and devices are able to auto detect the highest speed that the device or switch is in connection with to support and adjust to run at…

physical parts of a computer, is one factor that has been constantly changing throughout the development of computers. Two elements of hardware in particular have progressed as generations go on: data transfer and storage. One challenge for computer engineers from the start was deciding how to transfer data through the computer. The first computer, the ENIAC, required 18,000 vacuum tubes to do so, and weighed about 20 tons. Because of its huge size, its power consumption was 150,000 watts…

in 1946; it was call the William Tube. It only holds 1024 bits of data. In 1950s, magnetic technology came along with tape and hard disk storage. Magnetic tape became more popular because it was cheaper to produce and more reliable comparing to the hard disk at the time. One big draw back for the magnetic storage was it is slow and the data reading is sequential which means the computer cannot skip to access a certain piece of data. Magnetic disk technology developed into many forms, a popular…

the pixels on the screen will be used to create the image then information that is creates is sent to the monitor through a cable. The graphics card has four main parts that it uses to complete the tasks. These are the motherboard where the power and data is connected through a connector, the processor this tells it how to use each pixel on the screen, memory which holds the picture and the monitor where the image will be displayed. The graphics card is normally built straight into the computers…

Datavast Study Case 1. Describe the data storage industry in China in this case. Include comments on technology and issues in accepting new technology. The data storage industry in China is relatively new and undeveloped. According to Hao, 40 per cent of SMEs don’t create backups of the firm’s information; 20 per cent still use CD for this purpose, which can be easily lost or broken and has capacity to store only 0.73 GB; and 30 to 40 per cent use external hard drives, that can store 2…

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…
