Information Technology: Structures of Data Essay

The nursing home page of the ITPRC clear direct introduces it as The Information Technology Professionals Resource Center (ITPRC, 2007). originally created in 1999, the avowed purpose of the meshing situation is to provide a integrity-stop shop for IT paids for technical education on data vaneing.The purpose is praiseworthy because data networking is a vital function which chthoniclies many of the devices and systems that make our in advance(p) life convenient and efficient such as computers, ATMs, cell phones, skyway reservation systems, and the like. Any resource which aids the understanding by the concerned professionals regarding this body of knowledge is beneficial to society as a whole, straightaway or indirectly. On the opposite hand, the subject matter of this Web site is so highly technical, extensive and rapidly evolving that it must be very difficult to primary(prenominal)tain it and keep it abreast of developments.Comprehensive DiscussionThe cogitate in the home page are grouped into four main purposes (1) Career Management, (2) Technologies, (3) Operations and (4) Others. The ITPRC Web site may thus be considered as a entry that leads to other Web sites which might be of interest to the network engineer in the areas represented by the headings (Deitel, 2001, pp. 35-37).The middle of this Web portal is the Technologies group of associate. Under this group the link titles almost correspond to the OSI reference manikin for network architectures (Martin, 1988). This is a conceptual model which is well-known to networking professionals and even those at the student level. They are greatly aid by this grouping scheme in organizing their searches for resources on the Internet.For instance, under the heading Technologies, we pass the links Physical, Data Link and Content vane, while the OSI model has the bottom layers Physical, Data Link and electronic network. The Technologies Physical link points to Web sites on modems, cablin g and other devices which a network engineer would expect to find under this topic. The other ITPRC links under Technologies roughly correspond to areas covered by the remaining layers in the OSI model, to wit the Transport, Session, Presentation and Application layers (Martin).The Operations category of links provides information on organizations (business, government or NGO) which run networks, software tools for measuring network exertion such as response times for messages sent over the Internet, and other software for monitoring security conditions or threats such as retell hacking attempts.The links classified under Others point to a treasure trove of information in the form of Web sites containing dictionaries, glossaries and FAQs pertaining to computer and networking terms. And if the researchers mind is having difficulties in untangling the complexities of networks, there is the Humor link to Web sites which provide comic relief.A Helpful Chain of Links deem I were a gra duate student who sets push through to understand the development of the Internets transmission control protocol/IP message routing techniques. In the ITPRC home page under Technologies I will brattle on TCP/IP FAQ. This brings up a Web page where I will click on the link Where can I find RFCs?1 That leads me to the page on The Definitive RFC Repository which mentions the URL . When I click on that URL voila out comes the RFC Editor Web site (RFC Editor, n.d.) which includes a search engine for all RFCs, from the earliest RFC dated 1969 to the a la mode(p) one published in 2009. This is just one example of the richness of information sources that are accessible through the ITPRC portal. One could follow other bondage of links to Web sites which eventually lead to the information sought after.A Useful Professional ResourceThe ITPRC has links to Web sites that meet a wide variety of the needs of data networking professionals. We have seen earlier how the portal could be useful t o a graduate student. For an engineer on the job, it has links for finding information related to workaday matters such as the latest viruses circulating on the Internet.For a technology manager who is about to participate on an upgrade of the enterprise network, the industry news links would be useful starting points for learning about developments that could keep his company at par with or ahead of its competitors. Thereafter he could direct his supply to conduct in-depth research on the technology behind the new harvest-tide offerings and the likelihood that the products have been thoroughly debugged.The network professional looking out for an opportunity to advance his career in another company would find the Job Databases links invaluable.Other ObservationsThe links to some of the sites are no longer valid. Under the Book Sites link, the very first two Web sites no longer exist. The third Web site, Half Price figurer Books, does not live up to its title. You have to keep on clicking a number of Web sites in succession before you come up with any site that offers substantial discounts on computer books.Bottom delineateThe ITPRC site is a very useful portal for the data networking professional in the sense that beginning with just one Web site he is directed to the sources of tons of information in the data networking field.
