  2. Explain the user side and server side factors that influence the performance of a website

    The modem converts received data to digital and vice versa. Because dial-up uses telephone lines the quality of the connection is not reliable and data rates are limited. A dial-up has an average speed from 2400bps to 56Kbps. It isn?t used widely today as it has been replaced with more efficient options like DSL and Broadband. ISDN is another internet connection. It stands for Integrated Services Digital Network. It is an international communications standard for sending voice, video and other data over digital telephone lines or normal telephone wires. The average speed ranges from 64kbps to 128kbs.

  3. Explain the postives of introducing an e-commerce system to an organisation

    Because websites can be automated, there doesn?t need to be any staff like there is in highstreets stores. This also means more customers can shop when it?s convenient for them. Amazon would have been easy to set up because they don?t need premises, electric, water and other essential things when opening up a traditional store but only need a website and things that need to maintain the site. Relatively low start-up and running costs means it?s easy for people to start their own business. For a traditional store, you will need to buy property to have your store, overheads like electric and shelves to hold the stock which can all add up to be pricy.

  4. Examine the social implications of e-commerce on society

    E-commerce is becoming even more popular and putting threat on traditional high street stores. For people with limited or no access to the internet ecommerce becomes less effective. Families may not be able to buy a computer and pay monthly for broadband meaning they cannot take advantage of lower prices. This is known as the social demand. Brick and Click organisations are changing the way people shop. Before e-commerce people had to physically go to the store but now they can buy these products whenever they want in the comfort of their home. This has led to different ways businesses run, to patterns of customer behaviour and to the businesses which exist in our high streets.

  5. Evaluate the use of e-commerce in a brick and click organisation

    Again it helps Asda to increase their customers. Without e-commerce Asda will only be able to sell goods to a customer near their store?s location. Another advantage is 24/7 trading, it means that Asda can sell their products 24 hours a day and 7 days a week. So again its flexible selling time enhances sales as customers can buy product whenever they want. This has an advantage over their brick stores because they will close at certain times whereas its 24/7 online.

  6. Discuss security issues in e-commerce.

    This knowledge can help them log in to your private online accounts. Firewalls are central points of attack. Firewalls are designed to prevent unauthorized network intrusions; however, if an intruder or malware slips through the system, your computer becomes vulnerable to additional system attacks. Once installed, malware can actually disable the firewall and processes used to run it, which is especially easy if you have no anti-virus software. A firewall, especially the Windows Firewall, is designed to block activities that look suspicious. Unfortunately, a block can also extend to legitimate network-intensive processes. In some cases, even running a legitimate program such as a messaging program or social networking plug-in won't work if your firewall concludes it's a malicious process.

  7. Evaluate the performance of a computer system and explain and justify improvements that could be made to a computer system.

    Furthermore, I changed the motion of the pointer to be slow to medium. This is because again it will allow the user to navigate more easily as it won?t be moving too fast that they cannot keep up. Keyboard I chose to allow the on screen keyboard this was done in to ease of access. This is going to make typing easier for the user as they can change the size of the virtual keyboard. The user may want to have an extremely large keyboard and therefore this gives them the option.

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?
  • To what extent does research support a link between stress and the immune system?

    "In conclusion to the experiments it is seen that stress is almost a definite cause of a suppressed immune system although it may not be the only reason that the immune system is suppressed. As it is not entirely sure whether stress causes the suppression of the immune system or the suppressed immune system leads to stress."

  • To What Extent Was the Poor Law a New Poor Law?

    "The new poor law was a new poor law. Due to social, political, and economical circumstances, it was necessary for the time, as the old system was ineffective, inefficient, and bad for the poor. The new laws meant that there were tighter controls over the parishes and the poor; this made less chance of uprisings and rebellions. I agree similarly to the ideas of Digby; recent investigations on the Old Poor Law have produced convergent conclusions. They emphasise that relief under the Old Poor Law was essentially a response to population growth, under-employment, and low wages, rather than their causes as the Royal Commission's report alleged."

  • This research that I've done will discuss about the effectiveness of the Light Railway Transit (LRT) in Kuala Lumpur.

    "10.5 CONCLUSION In a nutshell, Hong Kong's Mass Transit Railway and Malaysia's Mass Transit have some similarity in term of technology and facilities. However, Hong Kong's Mass Transit Railway is more advanced than Malaysia's Mass Transit as they had started very early in the late 60's. Effectiveness of Malaysia's Mass Transit can be improved gradually and hopefully they can be as good as Hong Kong's Mass Transit Railway. APPENDIX 1. Map showing Hong Kong mass transit routes.
