Pros and Cons of Network Security - Essay Example

College: Essay Questions Qn Working as a telecommuter will have several advantages and disadvantages. Before taking theopportunity as a telecommuter, there are several assumptions that would be made. One of the assumptions will be the reduction in the cost of fuel that is incurred daily during driving to work. It is obvious that there is a huge cost of fuel as the distance from home to the current job is 60 miles. As a telecommuter, the cost will be done away with. Another assumption is reduction in costs of maintaining the vehicle that is used to drive to work. Although, it may appear as less of a cost, maintenance of the vehicle takes a considerable amount of money for maintaining it. Another assumption that will be considered is the time taken. Driving to and fro work takes a lot of time and effort than being a telecommuter. There are several valid reasons that would prompt one to consider the telecommuting offer. One of the reasons is reduction in expenditure. The telecommuter job will help in reduction of vehicle associated costs like fuel and maintenance costs. Consequently, one will have an increased amount of money for expenditure at home. The second reason is convenience. The telecommuter job will be convenient in terms of time taken and effort. The time taken to drive to work and effort used will be reduced. Thirdly, the job will reduce the risks associated with driving to work like accidents and insurance. While the current job is a race against time, the telecommuter job will be less of a burden. Fourthly, the telecommuter job will reduce the time taken to access the job location and also drive back home. This will increase the time that one can dedicate to the care of the baby. This in turn reduces the costs of childcare. Fifthly, the job reduces the distance that one has to commute to and fro work. The telecommuter job will result into pay reduction, which will affect the money available for expenditure. Secondly, it will reduce the comfort that one enjoyed as they drive to and fro work. Thirdly, the telecommuting job may not be luxurious as the current job and may have a lot of hardships. With lack of experience in the job, one is likely to face many problems. Fourthly, there may be no guarantee of how safe one will be on the job. Telecommuting may be an unstable job and may not guarantee job tenure. Fifthly, the telecommuting job may not offer the chance to grow career wise and one may stagnate in one job. As per my decision, I would prefer to remain in my current job rather than taking up the telecommuting job. Qn: 2 The internet is currently the main domain that the world relies on for most of its operations. The internet enables a large host of information, activities, operations and other major world actions to go unabated. The world of security, business and scientific exploration and development relies on the internet. Since it was discovered, various bodies have been tasked with expanding its ability and operations. A principal operational aspect of the internet is the ip address. In 2000, ICANN attempted to add to the existing ip addresses with no meaningful achievements. The ip addresses failed for various reasons. In calling for the proposals for the domains, ICANN produced a limited number of experimental ip addresses that did not achieve much after their introduction. Another reasons why the domains failed to achieve their goals was the inherent mismatch between the few required domains and the large number of proposals received by ICANN. This raised a platform for an increased number of proposals being left out (ICANN n.pag). IPv4 is an earlier version that was created in the 19th century from the 70s to 80s and its application is therefore limited. Initially, it was meant for connecting educational facilities and government institutions. Its inability to host a lot of addresses makes it unsuitable for the growing use of the internet. IPv4 limits growth of internet and slows down the applications. On the other hand, IPv6 offers a wide space of hosting many internet addresses and provides mobility. IPv4 is not secure and does not therefore guarantee private data and information confidentiality. IPv6 provides several features that guarantee security to private data (Ullrich par. 3-4, 6). Qn: 4 A cell phone is an essential commodity in one’s life and currently it in an indispensable part of people’s life. Daily transactions need one to have a cell phone that facilitates communication, as well as, other major functions that define people’s lives. Technological development has produced different types of phones with applications that are brilliant and that make life easier. The current generation of cell phones comes with applications that have enabled people to carry out many activities including communication, business and photography, all from one gadget. There are several uses that I consider a cell phone useful. One of the major and basic functions is communicating. A cell phone is a general communicating gadget that is used to connect people over long distances. However, I would consider a cell phone as a communicating gadget if it has advanced applications like teleconferencing. Communicating alone is not enough. Cell phones need to do more than conveying sounds from one speaker to the other. A cell phone that I consider useful should have the capacity to support communication with more than a single individual at a time, convey the image of the caller and can be used to represent one in a meeting in absentia. Another use of a cell phone is browsing and accessing the internet. A cell phone that I would consider useful must have browsing capability. The internet is crucial in communication, getting information and disseminating it. The cell phone must access applications like email, and social websites such as Twitter and Facebook that serve my communication purposes. Another feature that I would like in a cell phone is the photography application. A cell phone that I will consider useful must have a camera with high resolution. It must have the ability to take high quality photographs that can then be sent to friends and family through the internet. Another feature that I would consider in a cell phone is its simplicity to use. Cell phone applications must be presented in a user-friendly way. They must be accessed easily. The cell phone must also have a host of applications that can be downloaded and used as per the user’s discretion. The cell phone must be portable and durable. In the search of a cell phone, I would consider the above factors to the latter. However, the search of the phone would be limited to their available protocols. Current generation cell phones have a wide range of applications that one can choose from. Therefore, finding a cell phone with the desired features will not be a problem. Extra Credit The past few years have experienced a significant surge in registrations of domain names under major generic top level domains (gTLDs) and country code top level domains (ccTLDs). This rapid increase in domain name enrollment has significantly increased their gainfulness to both registries and owners, be it individuals or nations at large. Other country codes have gained notably from being licensed for commercial purposes internationally. One such recognizable ccTLD is .tv. The latter is a ccTLD for Tuvalu, which is a tiny island country. Formally referred to as Ellice Islands, Tuvalu is a Pacific Ocean island, geographically placed between Australia and Hawaii. Despite being far away from developed nations, and having little recognition, the country’s domain is extensively utilized in television, multimedia and entertainment industries. Consequently, this has exposed the country to the rest of the world and opened investment opportunities for it. Further, because of the significance of the domain names to the island’s general economy, they can perhaps qualify as Tuvalu’s primary export. This is evident from estimates that .tv contributed about 6.1% to the country’s gross domestic product (GDP) (Metcalf n.pg). Works cited ICANN. Reconsideration Request 00-8.
