Designing Networking (WAN) - Essay Example To transfer a 972.222kb data in less than two minutes we can have an Internet connection which has an upload speed of 32kbps. If we take 256 kbps of access speed connectivity then down load would be 256 divided by 4 and upload would be 256 divided by 8. These are standard calculation to choose an Internet connection. If continuous connectivity is required then we can choose DSL connectivity or else a dial up connectivity would be sufficient. A 256kbps dial up connectivity can upload 32 kb per second that is equal to 1920 kb per minute which is 3840kb i.e 3.75mb for two minutes which exceeds our requirement. This type of connectivity is ideal for Fargo to Denver. For a link to this configuration we need a DS3 dedicated link which can support a 45mb per second. This is the most ideal line type for the given data transfer. To have a DS3 link we need to have a multiplexer, router and a switch. Switch = Cisco catalyst 4605 which can support more than 200 users. A 45 mbps dedicated link would be the cheapest and reliable line type from Minneapolis to Denver which does not need an Internet connection. This connectivity is called a tie line. The same can be used for even voice connectivity from Denver to Minneapolis. For the St.Louis to Denver connectivity a 256 kpbs dial up connectivity would be an ideal line type. Since only a 100 kbps data transfer is needed. Dial up is advised since the connectivity needed is intermittent. The Nortel multiplexer is connected to a Cisco router and from there a Cisco switch is connected. From the switch we can many interfaces. Fargo and St.Louis connect to the main office through Internet. Only Minneapolis connect to Denver using a DS3 45 MBPS dedicated link. Nortel 7480 multiplexer WAN diagram showing four location connectivity Data transfer calculations for St.Louis. 100kb = 100/1024 = 0.09mb. a 256 kbps dial up would far exceed the 100 kbps requirement.

Trends of societal role Research Paper Example | Topics and Well Written Essays - 2000 words

Trends of societal role - Research Paper Example The researcher was burdened to uplift the view of the paternal role in terms of his involvement with his child, thus bringing forth the present study which integrates both quantitative and qualitative research methods, and which could aid future investigations in both areas upon reviewing this literature. Kazura (2000) purposes to look into the father and child relationship through the latter’s involvement in attachment behaviors, play interactions, and social interactions (p. ?). The research conduction is brief, lasting only a few minutes including the Strange Situation procedure and the three play segments, or probably a few hours if we take into account the home visits conducted by the primary investigator. This may seem inadequate, but its cross-sectional design is acceptable as the same is used in other studies; however, we should not neglect the possibility of different results if there is alteration in the time frame. Kazura presents several information in her paper, w hich would allow other researchers to review on. She explains the basics of her study thoroughly, and provides enough statistical data, leaving this study open for future modifications. Using Kazura’s study, analytical skills will be demonstrated in understanding the components of her research and judging them according to the expected deftness achieved in this course. In the present research, Kazura studies both qualitative and quantitative father-child relationships by digging deeper in their attachment, play, and social interactions.... Prior to this, several other undertakings aimed to explore father involvement in child-rearing as women take part in the workforce. Although society noticed that fathers somehow started to be involved with the previously solely-mother role, there are still contentions about their involvement and the influence of their presence as caregivers, especially in the early years of their children, are questioned. Kazura presented previous literature that discussed the hindrances of father involvement to child-rearing in the first few years of life but these were not specifically typified. Providing evidences that the relationship between the quantity and quality of fathering behaviors are not firmly established and that the length of time parents spend with their children does necessarily affect the latter’s developmental outcomes, the researcher intends to collaborate both quantitative and qualitative methods in determining parental involvement with their children, and uses this to c ome up with her hypothesis and conclusions. Because one of the researcher’s goals is to compare paternal to maternal involvement, intact families were chosen to be a part of the sample, which were obtained by convenience sampling, recruited through newspaper advertisements and local child-care centers. The 27 couples with their children belong to the middle-class, composing of 24 Caucasian families, two African-American families, and one Eastern Indian family. The children ranged from 12 to 26 months, where there were 14 males and 13 females. The sample size is small, considering that results of the study would tend to generalize the father-child
