    An introduction to Identity Theft

    4 star(s)

    * Business and commercial identity theft - used for obtaining financial services, charges against assets and obtaining goods. * Criminal Fraud - Using another's identity when held responsible for a crime. * Offences against the government e.g. benefit fraud and tax evasion. Prevalence & Statistics I.T. availability and understanding grows amongst the world's population as does the increase of Identity Theft. Those who perpetrate this crime constantly invent new ways of obtaining the victims personal and private information. In June 2005 http://www.identitytheftspy.com reported that its study returned that 13% of all internet users had stated that they or a member of their household had been the victim of identity theft.

As an industry IT is a significant employer worldwide and Computing is a key foundation in pursuing a related career. At A level Computing involves the study of a range of topics, from memory and storage to how microprocessors work, from systems architecture to programming and logic. There is a distinctive practical programming element to the course and you may be creating apps, websites or other types of creative coding solutions.

Whilst part of the course will be practically examined the majority will be assessed in examinations. You can gain valuable skills by accessing the Marked by Teachers Computing section which contains a wide variety of essay examples to help you master the essay skills required.

Computing does tend to sit well with Maths and Further Maths as other A level optionsbut Economics and Physics are also favoured subject combinations. As a successful Computing Alevel student you'll find your qualification highly favoured by Computer Science departments at University.

Conclusion analysis

Good conclusions usually refer back to the question or title and address it directly - for example by using key words from the title.
How well do you think these conclusions address the title or question? Answering these questions should help you find out.

  1. Do they use key words from the title or question?
  2. Do they answer the question directly?
  3. Can you work out the question or title just by reading the conclusion?
  • Neurophysiology - Discuss the roles of development learning and evolution in the construction of the nervous system

    "Conclusions The roles played by each factor described here each have their own specific effect on the construction of the nervous system. The evolutionary aspect controls the "blueprints" of the nervous systems that are hard coded into the DNA of the animal. However it is not specifically the genetic makeup of the nervous system that natural selection acts against, rather the phenotype of the nervous system, which is the combination of the developmental and the learning factors. The evolutionary factors alter the genotype, the only source of variation that can be passed down to their offspring. The development can only attempt to recreate the layout as specified by the different alleles; it cannot exceed them in terms of functionality. The true source of variation depends on the extrinsic information obtained and stored in memory, but that us not able to cross generations (with the exception of tradition) and so could be an explanation for the high evolutionary conservation of the nervous system."

  • Discuss the relationship that exists in the UK between the legal rules that govern directors' duties and principles of corporate governance.

    "The UK's approach to governance is a self regulatory approach unlike the US legislative approach. Brussels have looked into creating a European corporate governance code however they came to the conclusion it was not necessary and agreed that the European Union should create a common approach which would coordinate national corporate governance codes. If legislation is brought in it would defeat the point of corporate governance as it would cause restrictions on a company rather than the flexibility provided by The Combined Code. It is said that companies who follow a code of corporate governance have a more stable price/earnings ratio this is due to the management of their financial assets, the code helps them manage their assets more efficiently and so they are seen as more stable companies in which to invest. This in turn creates a confidence in investors who are willing to support the development of their company as they have faith in their investment due to the guidelines the company follows set by The Combined Code."
