Advantages and disadvantages of WAN

Advantages and disadvantages of WAN Assumption. The company consist of 4 buildings, one as headquarter which located in Kuala Lumpur, Malaysia and three as branches which located in Jakarta Indonesia, Bangkok Thailand and Manila Filipina. The company consists of 4 departments that are admin staff, IT department, marketing department and human resources department, which have total 40 employees in every office. Each department has 10 employees, which mean every departments room consist of 10 personal computers. LAN architecture will be the same between headquarter and branches. Every building Consist of 3 floors, 1st floors for administrator staff and human resources staff, 2nd floor for IT department and server room and the 3rd floor for marketing and meeting room. Every department has its own peripherals such as printer, scanner, and Photostat machine. Projector will be in meeting room. Have connection to the Internet and connection to each office. Headquarter office has external backup which located in Malaysia nearby headquarter office approximately 2 km, its provide backup for the database. Problem identification. The company does not have network yet. The company does not have DBMS (Database Management System). The company does not have backup yet. Security issues. WAN explanation. There are five sites in the WAN diagram, consist of headquarter office which is located in Kuala Lumpur Malaysia, three branches offices which is located in Thailand Filipina and Indonesia and one external backup which is located nearby headquarter office. The function of external backup is to keep the data as the original data. WAN topology. Basically WAN topology is almost similar with the LAN topology consist of point-to-point topology, ring topology and star topology. There are several advantages and disadvantages for every topology. The advantages and disadvantages of each topology will be shown in table bellow. For this company we suggest to use star topology because it is more s calable, provides shorter data paths between two sites and easy to add new nodes, if someday the company will expand the business by adding new branches in the other country it will easy to add to the existing WAN, the disadvantages of star topology is it has single point of failure at the concentrator routers. To overcome this problem network administrator tend to add some alternatives links between sites. WAN transmission technology. For WAN technologies we will do comparison between three technologies that are leased line, frame relay, X.25 and PPP. For WAN technologies we suggest to use frame relay because it can provide performance similar with the lease line with significantly less cost over long distance. Another reason is reduce internetworking cost because with frame relay required fewer port to access other network, increase performance with reduce complexity and definitely it is cheaper than leased line. Lower cost over long distance makes frame relay is good for this com pany because the branches office located across the country. Technology. For WAN technology we suggest to use VPN (virtual private network). VPN is alternatives technology to replace the more expensive WAN technology. The advantages of VPN that available online on: (http://www.universitydissertations.com/Communications/using-VPN.php) are, provide well security method, less expensive when compare with the WAN technology, reduce setup times, fast network link, simple network topology and productivity improved due to less constraints when compared with other networking methods. And the disadvantage of VPN is limited security for wireless users.

Motivating Secondary Schooling Children Assignment

Motivating Secondary Schooling Children - Assignment Example 195). Sockett's statement expresses a basic premise about the role of motivation: It leads to possibilities for fostering the development of students' potential or "life chances" (Mclnerney & Van Etten, 2001, p. x). In some rare cases the educator is lucky enough to have a group of students who all arrive with enthusiasm for the subject. They have well developed study skills and a strong aptitude towards learning. In these instances the task for the educator is to maintain this enthusiasm and to utilize it to ensure these already advanced students continue to achieve high levels of success. However, the circumstances for educators are often quite different. Their study skills may be underdeveloped and the academic learning may be less than impressive. It is for this reason that an educator should be armed with the knowledge and skill to develop or even create motivation. A central theme of this paper is that teachers have a primary responsibility in education to help students cultivate personal qualities of motivation that can give them resources for developing aspiration, independent learning, achieving goals, and fostering resiliency in the face of setbacks. Perhaps this responsibility is even more important in the context of the motivational problems and challenges faced in the home and in schools in the early 21st century. The research on the issue will include reviewing the literature on motivation and discussing of teaching approaches that stimulate students' motivation. The research paper will also focus on subject interest and draw upon the practical experiences of teachers faced with students whose level of interest in their subject matter is low. Student's discouragement to learn is not uncommon and arises widely throughout the educational system. During the years of compulsory education, the lack of motivation is a matter of constant conc ern. Students are faced with a wide ranging curriculum designed to provide a well rounded education. Amongst the myriad of research subjects there will be some favored topic/subjects, while other subjects may not be that interesting to an individual student. Successful teaching will almost inevitably require the adoption of a different approach to the teaching and learning activities undertaken. Definition and overview of motivation Motivation is a theoretical construct used to explain the initiation, direction, intensity, persistence, and quality of behavior, especially goal-directed behavior (Maehr & Meyer, 1997). Motives are hypothetical constructs used to explain why people are doing what they are doing. Motives are distinguished from related constructs such as goals (the immediate objectives of particular sequences of behavior) and strategies (the methods used to achieve goals and thus to satisfy motives). For example, a person responds to hunger (motive) by going to a restaurant (strategy) to get food (goal). Motives are usually construed as relatively general needs or desires that energize people to initiate purposeful action sequences. In contrast, goals (and related strategies) tend to be more specific and to be used to explain the direction and quality of action sequences in particular situations

Business External Environmental Assessment Assignment

Business External Environmental Assessment - Assignment Example According to the report findings the political environment is constituted by elected leaders and the policies they introduce. These policies could be aimed at regulating business through a range of business and corporate policies, amending the taxation system, protecting the environment, and customer protection. These factors are mainly controlled by the political class through legislations. Economic environment makes the most sense of all the factors. Comcast Corporation must always scan the economic environment to check how stable the economy is at any given time. Another aspect of the economic environment that must be investigated is whether disposable incomes of existing and potential customers is rising or declining. The extent of globalization and competition in the telecommunication and mass media industries too must be checked. The level of competition may be checked by determining if the market share is growing or shrinking.From this paper it is clear that  socio-cultural aspects of the environment in which Comcast operates entails issues like the population growth trend and the accompanying growth in the number of customers. Generational social attitudes and the society’s levels of education, health and social mobility also influence Comcast’s business decisions and industry standing.  These socio-cultural issues must be looked into after every predetermined lengths of time.

Effects of Increased Wait-Time on the Quantity of Correct Responses Essay

Effects of Increased Wait-Time on the Quantity of Correct Responses from Elementary ELL - Essay Example There has been an increase in the number of culturally and linguistically diverse students prompting education professionals to upgrade their skills and knowledge to ensure effective teaching in ELL classrooms. This has resulted in researchers and educational scholars seeking the appropriate wait-time teachers should give to ELL students. As such, ELL students pose a challenge to teachers because of their language-learning disability.The response that an ELL student gives to a question is determined by the level of his or her understanding of concepts and subject ideas, systematic ideas reflection, critical thinking, and content comprehension. However, effective learning for ELL learners does not solely contribute to a response given by ELL students. Wait time has a substantial positive effect on the response that an ELL student gives to a classroom question. Existing research classifies silence time in a classroom into eight categories including student-pause time, within-teacher pr esentation pause time, within-student’s response pause-time, post-teacher question time, student pause-time, post-student responsive wait time, teacher pause-time, student task-completion work-time and impact pause time. Despite the detailed wait-time classification, there has been no concrete conclusion regarding the specific wait-time required for elementary ELL students to respond to questions. ... elementary ELL students include long answers responses to questions by students, improved student participation through volunteering more answers that are appropriate, increase in the analysis and synthesis of the context which results to students giving evidence-inference responses that are more speculative (Cooper & Irizarry, 2013). Increased wait-time contributes to improved students’ self-confidence in responding to questions, increased rate of student asking questions regarding clarity as well as higher students’ achievement. Simply by increasing wait time, especially to students who have to translate the question into their mother tongue and then critically evaluate the questions to give a response, teachers may influence the quantity of correct responses to questions (Cooper & Irizarry, 2013). According to Mohr and Mohr (2007), a teacher should allow sufficient wait time to support ELL students to switch from hearing in a foreign language into reasoning and think ing in their first language, and then giving the response to the question. Additionally, increased wait time has proved to enhance the cognitive techniques applied by a student to give responses (Bluck & Gilbertson, 2006). Relationship between Increased Wait-Time and Critical Thinking Several studies such as those conducted by Beyondpenguins.ehe.osu.edu (2013) and FEAweb (2003) indicate that teacher’s wait time is often associated with the thoughtfulness and comprehension of a student’s answer to classroom questions. Notably, teachers do not give sufficient time for students to internalize, think critically, and seek comprehensive knowledge to respond to classroom questions. Teachers who give elementary ELL students a few seconds to respond to classroom questions evoke student recall on a subject

The Boston Molasses Disaster Essay Example | Topics and Well Written Essays - 2500 words

The Boston Molasses Disaster - Essay Example A lawsuit was filed against the company and a bitter legal battle ensued after the disaster. Negligence and errors in design were finally proved to be the most obvious reasons explaining the tank failure. This event raised public morale to combat high handed corporates who did not pay much attention to environmental issues and public safety. And the technical aspects of the disaster are also extremely vital. A simple and stationary storage tank had behaved in a strange manner. This signals poor understanding of chemical engineering. Designing a storage tank is not just a mechanical engineering topic. Chemistry of the material to be stored in the tank is highly important. Continual research on the Boston Molasses Disaster can help the engineering community to learn from past mistakes and understand the importance of industrial safety in the context of holistic disaster management preparedness. Background The Boston Molasses Disaster: What happened? The Center for Chemical Process Safety or CCPS has furnished a very concise but informative description of the Boston Molasses Disaster. On 15th January 1919 morning, a large storage tank in northern Boston blasted releasing tons of molasses. The steel tank was 50 ft or 15 m high. It had a diameter of 90 ft or 27 m containing nearly 2.3 million US gallons of molasses. All the rivets sealing the tank walls were spattered in the manner of machine gun firing, and chunks of steel were hurled across the area. Consequently, a wave or molasses rising above 15 ft or 5m began to surge ahead from the site of the blast. The wave had a speed of about 60 km/hr and traveled across two bocks of the Boston city with great momentum. Consequently, 21 people were killed, above 150 were injured, several buildings and vehicles were smashed, and the municipal system was completely disrupted. See Figure – 1. (CCPS 2007) Figure 1: Photographs showing the site of disaster before and after the molasses tank failure took place. Source: CCPS (2007) 1.1.2 The technology/engineering involved The CCPS (2007) has utilized a sound technical a pproach to describe the disaster. This approach is contextual with relation to both the old and new paradigms of engineering. The old paradigm of early 20th century engineering technology was devoid of facilities like computer aided design (CAD), industrial control systems, etc. The new paradigm is modern 21st century engineering which has power of new discoveries and superior computing efficacy. In sum,

Evaluating international business communications situations Essay - 11

Evaluating international business communications situations - Essay Example Globalization has been known to provoke massive reactions in regards to its effects, both positive and negative, though the new opportunities it creates to people cannot be overemphasized. The creation of multinational companies all over the world is one such major opportunity that globalization creates, and this tends to encourage the interconnection of people from very diverse cultural and social backgrounds that would otherwise never have come together. As a result, globalization has produced workforce with the diverse cultural backgrounds at the same workplace and/or business encounters who have to work at an international level. These cultures are represented by individuals who come together at the workplace and have to learn how to communicate and tolerate one another with their diverse backgrounds. Intercultural communication occurs whenever a message is produced by a member of one culture for consumption by a member of another culture, a message must be understood. Because of cultural differences in these kinds of contacts, the potential for misunderstanding and disagreement is great (Pinto, ). Communication can only be said to be effective when it reaches out to the receiver in the manner in which it was intended to by the sender. As such, the idea, information or opinion being transmitted to the receiver must be carried out in a manner that ensures it is correctly understood, and that it is received on time by the receiver. This aspect emphasizes the importance of choosing the right mode of communication at both the individual as well as the organizational level for optimum communication. The various forms assumed by communication include formal vs. informal communication and verbal vs. non-verbal communication among others. Informal communication method is the one whereby the flow of information does not follow the known and established organizational channels. People make communication using unofficial lines that tend to follow
