Answer: True Page: 518 LOD: Easy 3. An historical advantage of using conventional files has been processing speed. They can be optimized for the access of the application. Answer: True Page: 519 LOD: Easy 4. Duplication of data items in multiple files is normally cited as the principal disadvantage of file-based systems.
Control Users have much more control of their file system and operating system in a command line interface. For example, users can copy a specific file from one location to another with a one-line command. Although a GUI offers plenty of control of a file system and operating system, the more advanced tasks may still need a command line. Multitasking Although many command line environments are capable of multitasking, they do not offer the same ease and ability to view multiple things at once on one screen. GUI users have windows that enable a user to view, control, and manipulate multiple things at once and is much faster to navigate when compared with a command line.
Making sure you have sufficient……… is one of the biggest factors in performance, even more than disk and processor. 5. For the processor to communicate with the rest of the system, the processor plugs in or connects to a large circuit board called the…….. . 6. Firmware is software contained in …….
Quick and easy – it is very quick and easy to collect information from respondents from Surveys, though creating good surveys and analyzing can consume considerable time. 6. Objectivity and bias – surveys offer high objectivity, clarity and very low bias because responses options can be designed per requirements. 7. This technique can be used by project manager or other team members with limited effect on validity and reliability on the survey results Examples of Questionnaire and survey Here are some examples of survey questions during
This has led to a plethora of more or less standardized file structures for all imaginable purposes, from the simplest to the most complex. Most computer files are used by computer programs which create, modify or delete the files for their own use on an as-needed basis. The programmers who create the programs decide what files are needed, how they are to be used and (often) their names. Explain how an operating system manages multiple processes… Memory management is the function of a computer operating system responsible for managing the computer's primary memory. The memory management function keeps track of the status of each memory location, either allocated or free.
There, this thinking was temporary and easily imitable which may cost much later in future. Speed considering the availability, with the service and reliability is the positive aspects of using co relation of servers with the exchanges. These facilitate in networking and are sustainable benefits. It also enhances the productivity of the costumer. 2) Tony Bishop of Wachovia stated that “Competitive advantage comes from your math, your workflow and processing through your systems.” Referring to what you have learned in this chapter, developing opposing viewpoints as to the role of IT, if any, in the development of competitive advantage.
Network operating system based file servers running Windows Server or Linux was once the primary solution for network storage, however reliability concerns and the need for a more efficient way manage data required a more robust system. That is where NAS (Network Attached Storage) and SAN (Storage Area Networks) come into play. NAS and SAN both have advantages and disadvantages. NAS systems offer a simple and cost effective way to expand storage capacity as well as backing up and protecting data. The benefit of an NAS system comes in its simplicity.
Describe and evaluate the working model of memory The working model of memory consists of many components, these are the central executive, the phonological loop- which also involves the articulatory control system and the phonological store, the visuospatial sketchpad and the episodic buffer. The central executive is considered the most important part of working memory, because it controls attention and coordinates the actions of the other components, it can briefly store information, but has a limited capacity. The central executive can store information from any kind of code. The phonological loop consists of two parts, the articulatory control system and the phonological store, The articulatory control system rehearses information verbally and has a capacity of about 2 seconds. It is the system that you use to mentally rehearse information by repeating it over and over again, it is also known as the ‘inner voice’.
Assignment 3: Understanding the Basics of Databases School University CIS 106 – Introduction to Information Technology Professor Date Understanding the Basics of Databases Databases are used to organize a collection of data, allowing for easy access, retrieval, and use of information. The first databases were slow at processing information and inconsistent when applications would require the same information, but kept in different files. Relational databases, normalization, and Structured Query Language have improved the efficiency of databases. To be a proficient database programmer, one should have a basic understanding of rational databases, normalization, Structured Query Language, and the use of database models. Relational Database The use of shared files reduced the problem with inconsistencies but was still not an efficient in accessing information.
Overall, overseeing assets, offices, and transmission in real-time. "Extensions" alludes to ways that an ERP environment can be "expanded" (supplemented) with outsider programs. It is in fact simple to uncover most ERP transactions to outside projects that do different things. On the other hand, on the grounds that ERP applications normally contain modern decides that control how information can be made or changed, some such capacities can be exceptionally hard to execute. This is the place outsider suppliers may go about as an augmentation of their IT group.
